Safety reasons that use mud gas separator in oil& gas drill site

Mud gas separators are commonly used during oil drilling operations, particularly in situations when extraction is likely to yield a large volume of gas.

Often referred to as degassers, these systems offer many benefits when drilling operations are centered on mud columns that are below optimal balance, and in so-called “sour gas” environments when there is a high concentration of hydrogen sulfide in the drilling fluid. Tech-Fab fabricates and manufactures custom mud gas separators for the oil and gas industry and more.

mud gas separator

For safety reasons, mud-based deposits of free gas must be removed from the drilling fluid, and most mud gas separators use uniform technologies to achieve this objective.

Drilling fluid enters the machine through an inlet and is passed over a series of baffles, where physical separation of the gas and the mud takes place. Extracted gases are then rerouted through a flare line for safe elimination, while the mud is fed through a shale shaker before ultimately being deposited in a storage tank. The speed of mud gas separators is measured in gallons per minute, representing the maximum intake capacity at the inlet.

DC Solid control offers a range of mud gas separators and degassers for clients engaged in drilling and extraction activities. To learn more, or to request a price quote, please contact adela@dcmudcleaningequipment.com

What is the mean of drilling mud circulating system

The circulating system is one of six major aspects of the rotary drilling process. This system coins its name from the action of circulating drilling mud, water, or oil based fluid mixed with various chemicals and clays, to bring rock cuttings to the surface during the drilling process.

The drilling mud is circulated through many different components of the mud circulating system. The main components of the circulating system include (1) mud pumps, (2) mud pits, (3) mud-mixing equipment, and (4) contaminant removal equipment. The circulating system is a continuous loop of travelling drilling mud during the drilling process.

solid control system

Drilling mud travels from mud tanks to the mud pump, from the pump through the high-pressure surface connections to the drill string, through the drill string to the drill bit, through the nozzles of the bit and up the annular space between the drill string and hole to the surface, and finally through the contaminant-removal equipment back to the suction mud tank.

The circulating system of a drilling rig is one of the most important aspects of a drilling rig. Without the components that make up the circulating system it could not fulfill its main duty of removing the rock cuttings from a drilled well.

Three types of shale shaker used in drilling fluid circulation system

Linear motion shale shakers represent the newest shaker technology and are the most common approach to solids control in the oil and gas drilling industries. They produce linear motion via a pair of eccentric shafts rotating in opposite directions. Linear motion shale shaker provides superior cuttings conveyance and is able to operate at an uphill slope to provide improved liquid retention.

shale shaker

Balanced elliptical motion shale shakers are especially effective while drilling top-hole sections where heavy, high-volume solids are present. On a balanced elliptical shale shaker, the difference in power between the two vibrating motors results an unbalanced force. With this setup, elliptical motion shakers can effectively remove solids and eliminate larger particles in drilling fluids. The relatively moderate vibration strength of balanced elliptical shale shakers can reduce the screen consumption.

shakers

Circular motion shakers have a single vibrator shaft located at the center of mass of the shaker tray. A motor drives a concentric shaft fitted with counterweights, providing pure circular motion along the length of the vibrating tray. This feature improves solids movement off the deck compared with unbalanced elliptical designs. The circular motion transports solids along the screen reducing the loss of drilling fluid. Circular motion shale shakers are often operated as stacked units with the coarsest screens on the top deck becoming finer on the lower decks.

Marketing used of Desander and desilter hydrociclones

Desander and desilter hydrociclones are device to separate particles from drilling fluid, which is sorted by shale shaker in the first phase of solids control system. Usually they are located after shale shakers.

Desanders make separations between 40 and 100 microns and offer the flexibility ­­of mounting either one, two, or three 10” desander cones over a cone underflow pan. DCCSQ desanders are also available in vertical or inclined manifold stand-alone models, or for inclined mounting on Derrick shakers.

desander

Desilters are designed to remove silt-sized (20 to 74 microns) solids from drilling fluids. DCCNQ’s round desilters are simple to operate and easy to maintain. DC’S polyurethane hydrocyclone offers a high volume 4” cone, while providing contractors an economical replacement for less efficient older equipment.

desilter

The standalone desander/desilter hydrocyclone unit can be assembled above linear motion shale shaker to recycle the useful drilling fluids from hydrocyclone underflow screening by fine mesh screens. Mud cleaner which combines desander, desilter and dewatering shale shaker in one unit is often used in nowadays drilling applications.

The mud cleaner is designed to remove the drill cuttings

Mud cleaner is consisted of shale shaker,desander and desilter for oil&gas well drilling fluids treatment system. More importantly,mud cleaner works more effectively,especially in cleaning functions compared with separated desander and desilter.Sometimes,it can be used as a shale shaker.

cleaners

Mud cleaners are used to remove drill cuttings from drilling fluid, known as mud. The mud is a non-Newtonian fluid of variable viscosity that serves several purposes in drilling operations. Mud is used to drive the down-hole motor, cool the drilling bit, carry the drill cutting to the surface for disposal, and maintain hydrostatic balance in the well.

mud cleaner

The mud cleaner is designed to remove the drill cuttings while allowing the weighted fillers of the mud, commonly barite, to stay suspended in the mud. The cuttings, consisting of solids greater than 74 to 105 micrometers, are filtered out in the staged process of the mud cleaner.

According to the customers’requirements, DC SOLID CONTROL company can design the mud cleaner which can meet almost all needs.

Function of drilling fluid and drilling fluid equipment

The drilling fluid circulating system is like a close loop electric circuit through which drilling fluid (i.e. mud) can travel from surface to all the way down hole and back to its initial point.

solid control system

The main component of the drilling fluid circulation system include shale shaker, desander, desilter, vacuum degasser, decanter centrifuge, mud tank, agitator, centrifugal pump. mud hoppers and ect. The drilling fluid circulation system also called solid control equipment or solid control system.

The function of the Drilling fluid and equipment maintenance cost can decrease greatly when proper solids control practices are utilized. From a fluid control stand point it would be desirable in most cases to remove all drilled solids. Although this is possible, it would be cost prohibitive.

The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with a minimum of cost.

 

 

Application Industries of the poorboy degasser/mud gas separator

Mud gas separator is commonly poor boy degasser. It captures and separates large volume of free gas within the drilling mud. If there is a “KICK” situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare.

Mud gas separator located at downstream of the choke manifold is one of the important well control equipment that you need to focus. It separates gas out of the mud after the gas comes out of hole.

mud gas separator

DCZYQ series mud gas separator combined with the Flare Ignition Device can be used together to ensure the drilling process smoothly. Our separator is divided into normal pressure separator and pressure auto-control separator according to the pressure.

The Mud Gas Separator is mainly used to remove the enormous free gas from drilling fluids, including poisonous gases like H2S. Currently it is widely used in Drilling Waste Management, oil & gas drilling, trenchless HDD, city bored piling, Coal Bed Gas Solids Control System, Oil Mud Seperation, mining, Oil Sludge Dewatering Systems, Water Drilling, environment protection etc.

Desander for treatment of waste water industry

Desanders are used to remove suspended solids from liquid process streams. One of the primary applications is to improve the quality of waste water. Treatment of waste water normally involves multiple process steps to remove the impurities and ensure that the final effluent discharge is compliant to regulatory specifications.

desander

A desander has an entry port near the top on the side of the vessel, a hydrocyclone central component, and two discharge points (one on the top of the vessel and one on the bottom). The hydrocyclone is oriented so that the wide opening is at the top and the narrow opening at the bottom.

Mining equipment of mud cleaner use introduction

Mud cleaners are two-stage solids control equipment that are composed of several hydrocyclones mounted over a vibrating screen, known as a shale shaker. Mud cleaners are used to remove solids from drilling fluid and act as 2nd and 3rd phase solids control equipment.

The mud cleaner is designed to remove the drill cuttings while allowing the weighted fillers of the mud, commonly barite, to stay suspended in the mud. The cuttings, consisting of solids greater than 74 to 105 micrometers, are filtered out in the staged process of the mud cleaner.

cleaner

The first-pass solids control devices of the mud cleaner are the hydrocyclones which are mounted over the vibrating screen of the shale shaker. Several hydrocyclones are used to increase the flow rate of the mud. There is also a combination of varying sized hydrocyclones. Smaller cones, typically 4″ in diameter known as desilters, remove finer silt sized solids, while the larger cones typically 10″ in diameter known as desanders removed the coarser sand sized particles.

mud cleaners

The vibrating screen of the shaker is sized for the specific drilling operation. Lighter mud with lower solids content would use a finer screen while drilling fluid with higher solids content, known as weighted mud, would use a slightly coarser screen in order to ensure that the weighted fillers are not filtered out of the mud.
