The effect is as follows: the device is arranged on the oil well Christmas tree nozzle sleeve, when the polish rod is broken and takes off, the device can effectively prevent the mixed liquid in the metering room from reversely leaking from the polish rod sealer, meet the normal production requirement of the oil well, and effectively reduce the pollution caused by oil leakage.
Description
Technical field
The utility model relates to technical field of petroleum extraction, and particularly a kind of pumpingh well well head isolated plant is a kind of check device that prevents the mixed liquor reverse leakage in the manifold.
Background technology
In oil field pumping well was produced, disconnected taking off taken place and belonged to the production abnormal accident in polished rod.Polished rod breaks when taking off, and polished rod is brought under the effect of rod string gravity in the polished rod sealer (packing box).May produce two kinds of results thus, a kind of to be that oil pumper is installed the basis higher, and polished rod eye clamping plate bottom is bigger from the packing box distance, and polished rod is disconnected when taking off polished rod broken end is still outside packing box, and the deep well pump plunger is sat extremely in pump barrel, and oil well stops production; Two kinds to be that oil pumper is installed the basis lower, and polished rod eye clamping plate bottom is less from the packing box distance, and polished rod is disconnected when taking off, and the polished rod broken end falls in the packing box, and the deep well pump plunger is sat extremely in pump barrel, oil well stop production and well head out of control.For the stopping production of having no progeny of first kind of polished rod, only need in time to change a polished rod and can recover oil well production.And second kind of polished rod is disconnected owing to the polished rod broken end falls in the packing box, though the deep well pump plunger is sat extremely oil well stopping production in pump barrel, cause the mixed liquor in the metering room manifold oppositely to leak but well head is out of control from polished rod sealer (packing box) is a large amount of, cause well head, wellsite facility, facility by the oil-water mixture pollution in wide area, it is also contaminated finally to cause oil well to stop production.It is very big to handle the disconnected work difficulty of taking off of second kind of polished rod, at first will use a large amount of human and material resources to remove the pollution greasy dirt of well site, wellhead equipment, facility, changes polished rod recovery oil well production, particularly winter then and resumes production more difficult.
At present, take off the production loss that brings because of polished rod is disconnected and the cost that resumes production increases and the heavy work of removing contamination in order effectively to reduce, adopt the above pumpingh well of ten types at present in the oil field is furnished with the polish rod clamp submethod and solves because of polished rod breaks end and fall into packing box and go into to cause the mixed liquor in the metering room manifold oppositely to leak a difficult problem in a large number from polished rod sealer (packing box) at polished rod place, polished rod eye bottom.The light distribution rods clamp has effectively solved to a certain extent and has taken off the oil well that the brings difficult problem that stops production, reproduces, removes contamination because of polished rod is disconnected, has also brought into play certain effect on field production management, still, in use has following drawback:
1, can't be equipped with polished rod clamp (Oilfield Company safety in production regulation to packing box apart from oil well for bottom dead centre polished rod eye bottom less than 40cm, the packing box distance is arrived greater than 30cm in the polished rod eye bottom, squeeze when preventing that polished rod is descending and hinder operating personnel's finger), the oil well of not joining polishing bar clamp less than 40cm to the packing box distance for bottom dead centre polished rod eye bottom falls into the mixed liquor that causes in the packing box in the metering room manifold oppositely from polished rod sealer (packing box) leakage in a large number when the disconnected polished rod broken end of can't eliminating when taking off of polished rod takes place like this;
2, because equipped polished rod clamp has caused the inconvenience of merit figure testing equipment to install in the polished rod eye bottom.
The utility model content
The purpose of this utility model is: provide a kind of well mouth of oil well unidirectional ball check valve, being installed in well recovery tree mouthpiece puts, prevent that the polished rod broken end from falling into the mixed liquor that causes in the packing box in the metering room manifold and oppositely leaking in a large number in polished rod sealer (packing box), satisfy the production requirement of oil well simultaneously.
The technical solution adopted in the utility model is: the unidirectional ball check valve of well mouth of oil well, mainly form by valve body, valve seat, valve ball and valve bonnet, valve body is the cylinder bodily form, the stepped central hole is arranged in the valve body, it is characterized in that: valve body one end center-hole diameter is greater than 5～10 millimeters of other end center-hole diameters, outer wall at the little center of valve body nose end has external screw thread, can set the mouthpiece cover with well recovery and be connected.End at the big center of valve body nose end is fixed with a valve bonnet; In the valve bonnet centre bore diaphragm is arranged, 2～4 valve bonnet holes are arranged on the valve bonnet diaphragm, the valve bonnet hole is a through hole.The valve bonnet outer wall is positive hexahedron shape.In the big centre bore of valve body and on the centre bore step, be fixed with ring-shaped valve seats, a valve ball is arranged in the big centre bore of valve body.On the sidewall of the big center of valve body nose end, oil guiding hole is arranged.
Valve bonnet is the end that is weldingly fixed on the big center of valve body nose end.
Described ring-shaped valve seats centre bore two ends are taper seat.
The beneficial effects of the utility model: the unidirectional ball check valve of the utility model well mouth of oil well, being installed in well recovery tree mouthpiece puts, when disconnected taking off takes place in polished rod, can effectively stop the metering room mixed liquor oppositely to leak from polished rod sealer (packing box) is a large amount of, reproduce requirement after satisfying that the oil well ordinary production requires and polished rod breaks and taking off, the installation of the unidirectional ball check valve of well mouth of oil well is identical with the fitting operation of oil nozzle, effectively reduced because of running the pollution that oil causes, reduce cost of production and management cost, reduced personnel labor.
