Description
Technical field
The present invention relates to the oil and gas exploration field, be specifically related to a kind of centrifuge 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.
Summary of the invention
The present invention has overcome the deficiency of prior art; A kind of centrifuge that is used for treated drilling fluid is provided; Solve the existing treated drilling fluid bowl conic tube inwall 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 present invention adopts following technical scheme:
A kind of centrifuge that is used for treated drilling fluid; Mainly comprise screw feeder and rotary drum; Described screw feeder is fixedly mounted on the base and with main motor through bearing block and links to each other, and on screw feeder, has discharging opening, and discharging opening links to each other with the feed pipe that runs through the screw feeder center; Described rotary drum is provided with the deslagging cylindrical shell, and the deslagging cylindrical shell is provided with mud hole.
For making the present invention play better technique effect:
Technical scheme further is that this centrifuge that is used for treated drilling fluid also comprises the auxiliary motor that is connected with rotary drum 7; Described rotary drum is to link to each other with auxiliary motor through differential mechanism; Auxiliary motor drives the differential mechanism belt wheel and rotates; Through differential mechanism make spiral produce one leading or lag behind the rotating speed of rotary drum, after screw feeder had had leading or lags behind the rotating speed of rotating speed, the mud cake that just can will be attached to drum inner wall was shifted the deslagging cylindrical shell onto; Discharge rotary drum through the tap on the deslagging cylindrical shell at last, accomplish solid phase and separate.
Technical scheme further is that above-mentioned rotary drum is made up of big end semiaxis, straight barrel, vertebra cylindrical shell and small end semiaxis successively; The deslagging cylindrical shell is arranged between conic tube and the small end semiaxis; Have tap on the deslagging cylindrical shell, the end of straight barrel has spout hole, under action of centrifugal force; The solid phase particles that density is big in the drilling fluid is distributed on the outer circumferential edge of screw feeder; Under the effect of screw feeder, the big solid phase particles of density is finally discharged from the mud hole of deslagging cylindrical shell by the continuous deslagging end of pushing rotary drum to.
Technical scheme further is that above-mentioned rotary drum outside is provided with casing.
Compared with prior art; The invention has the beneficial effects as follows: the present invention fully takes into account solid phase and after discharging the discharge of cylindrical shell mud hole, can and wash away rotary drum outer wall generation wearing and tearing; Rotary drum is provided with the deslagging cylindrical shell; The deslagging cylindrical shell is provided with mud hole, with direct contacting of rotary drum outer wall, prevents to wear and tear and wash away when effective isolation has been opened solid phase and discharged mud hole.
