Description
(1) technical field
The utility model relates to a kind of mud circulation device, is applicable to mud circulation operation in oil well, the well probing.
(2) background technology
The mud circulation device is oil well, the requisite pith of well drilling equipment, and it is in drilling operation, with mud pressurized circulation use after treatment.The mud circulation device of prior art all adopts reciprocating piston pump as slush pump, piston pump is that pressure is big, discharge capacity is little with respect to the characteristics of other force (forcing) pump, therefore in the mud circulation device, adopt two or two above reciprocating piston parallels connection of pumps uses usually, satisfy the requirement of mud displacement in oil well, the well mud circulation.Power adopts motor to drive the slush pump main axis rotation by machine driving.
Above-mentioned mud circulation device promptly carries in high pressure, the float amount mud circulation effect better in the mud circulation of conventional well (7～13 inches of borehole diameter) or slim-hole (borehole diameter is below 7 inches) probing, but when being applied in the mud circulation of big hole (borehole diameter is more than 13 inches) probing, because discharge capacity is big, need the use in parallel of many piston pumps, cause mechanism's complexity, mounting arrangement difficulty.In addition, this mud circulation device medium power transmission adopts motor to drive the slush pump main axis rotation by machine driving, and the adjustment of slush pump discharge capacity realizes complicated operation by the cylinder sleeve of changing different-diameter.
(3) utility model content
Technical problem to be solved in the utility model provides a kind of mud circulation operation that can realize high pressure, float gauging well, well, can realize low pressure, big discharge capacity mud circulation operation again, and use equipment is few, and can easily adjust slush pump discharge capacity mud circulation device.
The technical solution adopted in the utility model is: the mud circulation device adopts two slush pump configurations, the piston pump of the centrifugal pump of low pressure, big discharge capacity and high pressure, little discharge capacity is connected in parallel between mud pit and circulation Trunk Line, mud by after the slush pump pressurization successively by Trunk Line, standpipe, hose, water tap, drilling rod, flow to drill bit, inject into well.Two pipelines in parallel and the Trunk Line that connect centrifugal pump, piston pump respectively all are equipped with valve control break-make.In power transmission, adopt motor to order about two hydraulic motors driven plunger pump and centrifugal pump respectively, realize the stepless speed regulation of piston pump and centrifugal pump, and then regulate the discharge capacity of mud system by the HYDRAULIC CONTROL SYSTEM loop by hydraulic drive.
This mud circulation device can also connect a reflux pipeline and connect a grouting pipeline on Trunk Line between Trunk Line and mud pit, and mounted valve is controlled break-make respectively.The effect of reflux pipeline setting is: because circulating mud can not inject in well from drilling rod when unloading single operation, centrifugal pump can quit work, but owing to need diversion after the centrifugal pump termination of pumping when restarting, take a lot of work during operating cost, therefore a reflux pipeline is installed, under the situation of not termination of pumping of centrifugal pump, realize mud low discharge circulation between reflux pipeline, mud pit.The effect of grouting pipeline is that probing runs into sandy stratum or other reasons, because mud permeates the ground when causing the mud loss, behind the additional mud, directly pours into mud by the grouting pipeline in well in mud pit, guarantees mud circulation device operate as normal.
When this device is applied to low pressure, big discharge capacity mud circulation operation, centrifugal pump work during normal circulation, piston pump is as interim stand by pump, because centrifugal pump is much bigger with respect to the piston pump discharge capacity, can satisfy the requirement of various mud displacements, therefore can satisfy the requirement of low pressure, big discharge capacity.When the centrifugal pump fault, can work with piston pump temporarily.When under handling situations such as special formation creeps into, needing higher mud pressure, use piston pump work, to satisfy the requirement of high-pressure delivery.
When this device is applied to high pressure, the operation of float amount mud circulation, use piston pump to meet the demands, centrifugal pump can be used as interim stand by pump.
Expansion as this programme, piston pump during two slush pumps dispose also can be changed to centrifugal pump, promptly dispose two centrifugal pumps, between the import and export of two centrifugal pumps, connect a valve, and a valve also is installed respectively in the import department of every centrifugal pump, control the break-make of these valves, can realize two kinds of connections of serial or parallel connection of two centrifugal pumps, when needs low pressure, big flow mud circulation operation, employing is connected in parallel, when needs high pressure, the operation of low discharge mud circulation, employing is connected in series.
The utility model is owing to adopt a centrifugal pump and a piston pump configuration in parallel or two centrifugal pump serial or parallel connection configurations, can satisfy the mud circulation operation of various oil wells, well, particularly need not use many pump works just can solve the low pressure in the probing of big hole well, big discharge capacity mud circulation problem, simplified the mud circulation device, adopt fluid motor-driven piston pump, centrifugal pump, made things convenient for the adjusting of mud circulation flow.
The utility model is described in further detail below in conjunction with drawings and Examples.
