Mud cleaner group used in Mico-tunneling fields
Micro-tunneling—Micro-tunneling has become very popular in Europe and is being used more frequently in the United States. Micro tunneling is the horizontal boring of a large-diameter hole (from 27 inches up to 10 feet) while simultaneously laying pipe.
Typically, this technique is used in cities when laying or replacing water and sewer pipe beneath buildings and heavily traveled roads.
To prepare for these operations, large-diameter, vertical holes, or “caissons,” are excavated allowing the drilling equipment and hydraulic rams to be set up at the desired depth. The caisson is excavated slightly below the equipment level creating a sump for the returned drilling fluid and associated drilled solids.
The returns are pumped to the surface by a submersible pump to a compact solids removal system, which typically consists of a shale shaker and mud cleaner mounted over a small tank.
ZCQ240 Vacuum degasser delivery to Pakistan
Vacuum degasser produced by DC Machinery is suitable for various supporting of drilling mud solids control system, it plays an important role in restoring drilling mud performance, and can also be an agitator with big power.
DC Solid control shipped 3 sets ZCQ240 vacuum degasser to Pakistan drilling company which is a local government company who had already cooperated with our company for about 3 years.
Vacuum degasser uses vacuum to release free and dissolved gas in water, and then discharge them through the automatic exhaust valve system. At the same time, the degassed water will be injected into system. This low gas content water is not saturated with highly absorbent for gas, it will absorb the gas in the system to achieve the gas water balance. Vacuum degassing machine repeats this cycle every 20~30 seconds. This movement in circles removes all the gas in the system.
DC Solid control can provide you 4 models vacuum degasser, ZCQ240, ZCQ270, ZCQ300 and ZCQ360. If you have interesting with it, please feel free to contact me soon.
Special design of DCJBQ Mud agitator from DC Solid control
DCJBQ mud agitators are an important part of the mud solids control system. TSC offers a variety of motor and impeller sizes to fit specific tank configurations.
The mud Agitator combines compact design with high torque performance levels necessary for a uniformly suspended flow of drilled solids throughout the mud systems.
Powered by 1500RPM (4 pole) explosion proof motor and connected through heavy duty gear reducer, this mud agitator transfers high torque at RPM to Impeller to perform the most severe mud mixing conditions.
Impellers are available in three types viz. six blade mixed flow turbine type, four blade axial flow type and three blade twisted profile type to achieve highest performance in different site and mud conditions.
Gear reducers are worm type or helibevel type depending on the choice of the user. Standard models are available in 20 H.P. & 10 H.P. capacity.
5 H.P. Chemical Mixer with inline gear reducer of 15:1 reduction with stainless steel impeller and impeller shaft is provided along with 5’ X 5’ X 6’ treatment tank is a single unit.
Solid control equipment desilter usage introduction
Desilter used in solids control system is the 3rd phase equipment. Desilter is set after desander and prior to decanter centrifuge. The flow rate of desilter separator is decided by cones number. Usually, we utilize 4″ cone for desilter.
Each 4″ cone holds capacity 12~15m³/h. To achieve desilter separation there should be centrifugal pump as cone feeding pump. Under pump transfer power, there will be sufficient pressure pull drilling fluid swirl in cones body. Then solids will be separated out by centrifugal force. Theoretically, desilter will get rid of solids sized over 15 microns.
Desilter structure
Including fluid feed inlet, fluid discharge pipe, desilter cones, the support frame, bottom shaker or mud chute. The main parts including hydrocyclone, shaker screen, spring, screen motor, and so on.
There are thousands of manufacturer all over the globe manufacture solids control equipment. Desilter is one small part of such equipment.
ZYQ mud gas separator designed by DC Solid control
The mud gas separator is designed primarily for the removal of entrained gas, from the drilling fluid. The ZYQ mud gas separator is designed in multiple capacities, to meet specific mud gas needs.
Mud/Gas Separator is a piece of special equipment for degassing gas-invaded mud in the first grade. It is mainly used to remove big bubbles above φ3mm in diameter and these bubbles refer to expanded gases in the fluids that fill in some parts of well annulus. Well kick even spilling out to the rotary table will easily occur if they are not removed.
Mud/Gas Separator Features & Benefits:
1. Separates and discharges the enormous free gas from drilling fluids, including poisonous gases like H2S.
2. Separated gas is carried by discharge lines to safe area for combustion.
3. The unit is ruggedly built and coated with anti-corrosion epoxy so as to ensure long service life when processing hazardous and toxic gases.
DC use high quality steel materials manufacturing normal pressure prevent H2S Mud Gas Separator,can effectively prevent the harmful gas erosion, ensure the man- machine safety production.
