Abstract
The utility model relates to the field of a petroleum and gas exploration and particularly discloses a centrifuge deslagging barrel body for treating a drilling fluid. The centrifuge deslagging barrel body for treating the drilling fluid comprises a cylindric main body (3), wherein the cylindric main body (3) is disposed between a tapered barrel body (1) and a little end half shaft (2) of a revolving drum, the tapered barrel body (1) serves as a main body, and a deslagging hole (4) is mounted on the main body (1). The centrifuge deslagging barrel body for treating the drilling fluid has the advantages that the mass is small, the processing difficulties are small, the processing cycle is short, the cost is low, the replacement is convenient, the entire revolving drum scrapping caused by the fact that solid phase substances abrade and scour the outer wall of the revolving drum is avoided, the deslagging barrel body and an abrasion resistant sleeve can be only required to be replaced in case of a serious abrasion, and the maintenance cost is greatly lowered.
Description
Technical field
The utility model relates to the oil and gas exploration field, is specifically related to a kind of centrifuge deslagging cylindrical shell that is used for treated drilling fluid.
Background technology
The drilling fluid of explorations such as petroleum gas and production drilling well is a kind of water base suspension or oil-based suspension that contains a lot of insoluble solid phase particles; In drilling fluid is handled; Centrifuge is commonly used to separate cutting grain tiny in the drilling fluid, also is used for the recovery like drilling fluid weighting materials such as bolognian stones.Centrifuge relies on the rotary drum of rotation at a high speed; The drilling fluid that drives in the rotary drum rotates at a high speed, produces the centrifugal force of hundreds of and even several thousand acceleration of gravity, forces the solid phase particles in the drilling fluid to be deposited on the drum inner wall rapidly; Drilling fluid gets into the screw feeder inner chamber through feed pipe; Get into bowl continuously from the screw feeder inner chamber again, the solid formation that is deposited on the drum inner wall is scraped rotary drum continuously by screw feeder, simultaneously; In an other side of rotary drum, the ring-shaped liquid of having removed the clarification of cutting grain flows out outside the rotary drum through one group of spout hole continuously.
Bowl is made up of major semiaxis, straight barrel, conic tube and minor semiaxis usually.Pending drilling fluid is transported to the screw feeder inner chamber through feed pipe; Get into the acceleration of rotary drum again through screw feeder; Produce the centrifugal force of hundreds of and even several thousand acceleration of gravity, under centrifugal action, harmful solid formation is deposited on the drum inner wall; Screw feeder pushes away solid formation toward small end continuously, finally discharges from rotary drum conic tube mud hole.
Common rotary drum outlet only is on the rotary drum conic tube, to have opened several square holes or circular hole at present, installs high-abrasive material at tapping, the protection conic tube.But the on-the-spot bowl outer wall that uses still can be washed away vestige by the solid formation wearing and tearing, causes whole drum even whole desk centrifuge to be scrapped.
The utility model content
The utility model has overcome the deficiency of prior art; A kind of centrifuge deslagging cylindrical shell that is used for treated drilling fluid is provided; Solve the existing treated drilling fluid bowl conical inner surface that is used for and to be washed away vestige, the problem that causes whole conic tube even whole desk centrifuge to be scrapped by the solid formation wearing and tearing.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of centrifuge deslagging cylindrical shell that is used for treated drilling fluid comprises the conic tube that is installed in rotary drum and the columned main body between the small end semiaxis, and main body is provided with mud hole.
For making the utility model play better technique effect:
Technical scheme further is the above-mentioned interlaced arrangement of mud hole.
Technical scheme further is that above-mentioned mud hole is provided with wear-resistant sleeve, and one section of wear-resistant sleeve is extended mud hole.
Compared with prior art, the beneficial effect of the utility model is: the utility model quality is little, and difficulty of processing is little; Process-cycle is short, and cost is lower, and it is convenient to change; Can and not wash away the rotary drum outer wall, cause whole drum to be scrapped, in case serious wear because of the solid formation wearing and tearing; Only need replacing deslagging cylindrical shell and wear-resistant sleeve to get final product, greatly reduced maintenance cost.
