GN ZJ20 solids control system:
1, assessment
ZJ20 drill drilling mud system is a set of physical and electrical control connected with sludge treatment system (sees attached figure a, ZJ20 solids control system configuration drawing), the system is especially including (1) mud is purified tank, (3), (2) the particular transition of mud movement platforms such as mixing tank through the manifold connection just about all tanks and forming the entire drilling mud solids control equipment system. The main equipment are: substance tank, ZS83 x 108-2 linear shale shaker, QJ250 x 10 x 2/100 mud cleaner , LW450 x 842 and decanter centrifuges, JBQ5. 5 kW mixer, JBQ7. 5 kW mixer, SB6 x5 centrifuge pump, NJQ50-3 mud gun, SLH150-45 jet mixing unit, etc .

ZJ20 drilling mud system design features of several crucial processes, to grading regarding drilling mud, in accordance with the needs of drilling technology with the overflow groove mud movement. Tank also could be employed for mud aggravating, mixed, mixing and filtering. Clear h2o pipeline in the clear faucet connection can provide water to the mud circulating system; compound powder can provide the equivalent chemical ingredients; Mud setting system can be mixed intended for mud cleaning system, supplementary; Mud gun canal and mixing system is usually fully mixing the slurry mud tank mud and mix. two, mud circulation:
Well outside the mud from the system (1) the slurry distributor for the mud purification tank, with the adjustment of the manifold sphincter muscle can be respectively or in the two vibrating screen as well, after dealing with the filter of mud into the orange sand, mud from settling tank through a discharge chute in the desanding tank; Desanding tank in the mud by one particular # sand pump suction conveying to 2/100 QJ250 x x 10 connected with mud cleaning machine, other than sand hydrocyclone after digesting desand hydrocyclone mud over the overflow manifold into the mud tank; In addition to the mud hopper by 2 # mud pump suction conveying in order to 2/100 QJ250 x times 10 of mud mud cleaning machine in the cyclone, the mud cyclone following processing of mud from the overflow manifold into (2) the transition of 1 #mud tank (centrifugal separation tank); Need to deal with the centrifuge, according to the program to open typically the centrifuge, restart submerged pump will be (2) the adaptation of the tank 1 # hold mud supply centrifuge for further purification treatment, right after processing of the mud by means of pulp out centrifuge tubing flow (2) the adaptation of 2 # tank (suction tank). Part of the flows via mud overflow groove to be able to (2) the transition of two # tank (suction tank). As shown in information 2 .
Mud pump by means of manifold and (2) often the transition of 2 # tank (suction tank) 12 "1. 0 MPa flange program is linked together, throughout the mud tank high butterflies valve switch to adjust, may respectively sampling (2) the actual transition of 1 #, a couple of # tank, and (3) the slurry mixing tank (sees attached figure three or more, mud pump suction slurry system flow diagram), delivered to the mouth of the well, so that it will complete a systemic circulation regarding drilling fluid purification.
