The detailed introduction of mud trip tank from DC Solid control
Trip tank is a small tank which has a capacity of 20 – 50 bbl and its shape is tall and shallow because it can effectively detect volume changes. The trip tank system has the ability to continuously fill the well and take return back to the tank. With this capability, it will keep the hole full all the time and the volume changes either increasing or decreasing can tell the condition of the well.
Each trip tank has a pump which will suck the fluid from the tank and pump into the well via the fill up line connected to a bell nipple under the rig floor. The fluid return will flow back via a return line and back to the trip tank. The float in the trip tank is connected to the wire and the position of the float will represent the trip tank volume indicator. What’s more, nowadays several rigs have installed the electronic instrumentation for the accurate volume measurement.
This will help personnel on the rig track what is going on the well very quickly and accurately. As you can see, the complete system allows personnel to monitor the well.
The trip tank must be maintained in order to avoid solid build up, pump and valve failure, leakage, etc. Moreover, it is very critical to frequently check the float and the electronic instrument to see if they are in good condition.
Three sets mud cleaner looks more beautiful in the heavy snow
The finished mud cleaner in the heavy snow looks more beautiful. The mud cleaners are preparing to ship to Russian at the end of this month.
Mud cleaners with the combination of a desander and desilter mounted over a powerful multi-functional shale shaker, Elgin’s line of mud cleaners offer both high performance and versatility for the operator.
With our in-house engineering and design capabilities, DC Solid control can integrate any number of hydrocyclone arrangements with any of our shakers. In all cases, DC Solid control’s hydrocyclones come with polyurethane bodies, where erosion resistant inserts are available.
Standard hydrocyclone cone sizes available include 4”, 5”, 10”, and 12” and can be provided in arrangements of one to 20 cones. For abrasive solids, DC Solid control can also fit our polyurethane hydrocyclones with ceramic liners to maximize equipment life.

A set of ZJ2000 solid control system delivery last night
DC Machinery mainly focus on solids and fluids control systems, closed loop mud systems and remediation services are all delivered with best-in-class design and efficiency.
Last night, the order from Russian ZJ2000 solid control system delivery to railway station.This successful cooperation between DC and the Russian drilling service company further expands share of DC solids control products in Russian market once again. Both parties have agreed to establish long-term strategic partnership in line with principles of mutual benefit and joint development.
Equipment Ordered:
Customized Triple Shaker: three four panel shakers on one skid with mud flow divider

DC Drilling Mud Solids Control System can realize the storage and mixture of drilling fluid, remove the harmful solid phase, maintain the performance of drilling fluid, content the demand in the special situation of drilling fluid cycle, weight addition, shearing and trouble removal, and can increase the drilling operation efficiency and safety effectively.
Drilling fluid centrifuge for Unweighted and Weighted Drilling Fluids.
Drilling fluid centrofuge is the 4 stage equipment of the oil& gas drilling fluid circulating system. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream.
DCLW centrifuges can be used in Unweighted Drilling Fluids and Weighted Drilling Fluids. Following is the maters of the centrifuge used in the different materials.
When centrifuging the unweighted drilling mud, keep in mind the following: the centrifuge with High G force as the solids loads are low. Adjust the weir to a deep pool to maximized solids separation. Control a smaller mud feed rate to increase residence time Operate centrifuges in parallel, not in series if multiple centrifuges are required.
With the unavoidably higher solids content of weighted mud, the increase of gel strengths and viscosity, as well as the degradation of ? quality associated with the diminution of particle size with time, can become a serious problem. The problem is caused by the increasing concentration of colloidal and near-colloidal particles that are to be separated from the base. Centrifuges are used to selectively remove these solids.
With high solids content of weighted fluids, torque is a problem when processing it, the following is some advice when operating the centrifuges. Increase pond depth. Reduce in rpm or run a higher conveyor differential. Process the mud at a reduced feed rate Centrifuges.
The professional mud tank designed for Oilfield
A mud tank is a large storage container used to hold reserves of drilling fluid, also known as drilling mud, for a drill rig. Drilling fluid is used to reduce friction on drill components to allow them to work harder and faster with less risk of breaking down.
Now, In DC workshop has a professional designed mud tank for oilfield. Numerous companies manufacture and refurbish mud tanks of various shapes and sizes for industrial use, and contractors who specialize in cleaning tanks and other drilling equipment are also available. The cost for tanks and associated services varies widely, especially when custom designs are involved.
Mud tanks are the base of solids control equipment. Mud Tanks for solids control system is divided into Square tank and Cone-shaped tank according to the shape of tank bottom. The main function of mud tank is storage, because the worked drilling fluids must stored to the next seperation or to the next recyclation, or to be reused.
DC Solid control are here to serve all your drilling equipment needs – if you don’t see it on this site, just give us a call or email. We can get it, if you need it!
What functions of hydrocyclone in solid control system
Hydrocyclones are simple mechanical devices, with out moving parts, designed to speed up the settling process. Feed pressure is transformed into centrifugal force inside the cyclone or cone to accelerate particle settling in accordance with Stoke’s Law #1. In essence, a cyclone is a miniature settling pit which alloys very rapid settling of solids under controlled conditions.
Hydrocyclones have become important in solid control systems because of their ability to efficiently remove particles smaller than the finest mesh screens. They are also uncomplicated devices, which make them easy to use and maintain.
Design features of cyclones units vary widely according to the size. The cyclones are made of composite materials and hold up to wear quite well. The size of cyclones in use varies from 12” down to 2”. The measurement refers to the inside diameter of the largest, cylinders section of the cyclone. In general, but not always, the larger the cone, the larger the cut point and the greater the thru put. Refer to the figures below:
Hydrocyclones are another important line of defense in the battle against the removal of solids from your drilling fluid.
