Embodiment Construction

[0023] The specific implementation manners of the present invention will be briefly described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 A drilling rig solid control circulation system is shown, which is characterized in that it includes six drilling fluid circulation tanks 1, one water tank 29 and two spare storage tanks 28, and the six drilling fluid circulation tanks 1 are arranged in a 2X3 array in sequence, The mud is purified through six drilling fluid circulation tanks 1 in sequence. An anti-slip escalator 7 is provided on one side of the tank surface of the drilling fluid circulation tank 1. The escalator 7 is hinged with the tank body and can be placed on the side of the tank during transportation. The tank bottom of the drilling fluid circulation tank 1 is provided with a tank bottom valve 6 for controlling the suction inlet of the mud suction pipeline. The outside of the drilling fluid circulation tank 1 is hung or attached with a...

Abstract

The invention aims at providing a drilling machine solid control circulation system, which has the technical scheme that the drilling machine solid control circulation system comprises six drilling fluid circulation tanks, one water tank and two standby storage tanks, wherein the six drilling fluid circulation tanks are sequentially ranged into 2*3 arrays, and the purification of slurry is completed sequentially through the six drilling fluid circulation tanks. The drilling machine solid control circulation system has the beneficial effects that the system is provided with five-stages of purification equipment including a vibration sieve, a sand remover, a desilter, a vacuum degasser, a middle-speed centrifugal machine and a shearing pump. The technical requirements of drilling fluid circulation, slurry weight increasing, shearing, accident processing under special conditions and the like can be met. The system has the advantages that integrated modularization is adopted, the mounting and the dismounting are convenient, the highway and railway transportation requirements can be met, and the crane loading and unloading and dragging in a well field can be realized.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a drilling rig solid control circulation system. Background technique [0002] Drilling fluid, also known as mud, is the circulating flushing medium used in the hole during the drilling process. In the initial stage of rotary drilling, the main function of the drilling fluid is to carry the cuttings from the bottom of the well to the surface, and at the same time have the functions of cooling and lubricating the drill bit and drill string, balancing the side pressure of the rock on the well wall, and bearing part of the gravity of the drill pipe and casing. When drilling, the surface system needs to be able to meet the needs of establishing circulation, and at the same time, the preparation and pretreatment of reserve drilling fluid should also be considered. In the actual use process, the loss of mud is relatively large. The traditional treatment method is to recycle...
