Abstract
The utility model relates to a perforating and oil producing and releasing combined operation type pump valve, which belongs to the field of oil machinery. At present, the perforating production is separateed from the oil pumping production. When a pipe column is taken out, an oil releasing device needs to be installed. The utility model is composed of an outer connecting cylinder and a pump valve core assembly. A pump valve core is arranged in the outer connecting cylinder. The utility model is characterized in that seal rings are respectively arranged between a connecting ring and a spacer ring and between the spacer ring and a guide body head. The outer wall of the guide body head is provided with a temperature controlled clamping spring. The inner wall of the Outer connecting cylinder is provided with a clamping spring groove. The lower part of the pump valve core is provided with an oil releasing control ring which is locked by a fixing cutting nail. The bottom of the outer connecting cylinder is provided with a stop ring and the lower part of the outer connecting cylinder is provided with an oil releasing hole. After a perforating gun is fired, the combined operation type pump valve can be used for production when filled a pressure of 10 MPa. When the producing pipe column is taken out and the combined operation type pump valve is filled with the pressure of 18 MPa, the pump valve core drives the oil releasing control ring to move downwards to cause the liquid to be released to a well from the oil releasing hole. Through the use of the utility model, the purposes of the shortening of construction time, the secondary pollution avoidance of the stratum, the perforation and the combined operation of oil producing and releasing process can be achieved.
Description
Technical field
The utility model relates to a kind of perforation, oil recovery, the draining connection is made pump valve, be during oil, the gas well of a kind of perforation that is used in petroleum industry and sucker-rod pumping produced with the supporting special-purpose tool of production of shaft column, belong to the petroleum machinery field.
Background technology
It is the important means of oil field development that perforation and oil pumping are produced, at present, existing oil, gas well perforation and oil pumping are produced and are separately carried out, promptly earlier oil, gas-bearing formation are carried out perforation, the perforation hole tubing string that then recurs is lowered to flow string, in order to guarantee when tripping out tubing string, liquid in the oil pipe is let out in the well, also a bleeder will be installed on the perforation tubing string, and such process was not only time-consuming, expense is expected but also cause pollution to the stratum easily.Similarly the patent No. is 96219138.8 multi-functional oil well bottom valve, can realize that the connection of perforation and oil recovery is done, and mainly is applicable to workover treatment.
Summary of the invention
The purpose of this utility model is to provide a kind of beam hole, oil recovery, oil draining function to make pump valve in the connection of one, by redesign to the pump valve structure, reach the purpose of simplifying perforation, oil recovery, draining process, both improved timeliness, also prevented pollution oil-well strata.
The utility model adopts following technical scheme: promptly a kind of perforation, recover the oil, the draining connection is made pump valve and is made of outer connecting cylinder and pump valve core assembly, the pump valve core assembly places in the outer connecting cylinder, pump valve core assembly in the outer connecting cylinder is from top to bottom successively by valve bonnet, valve body, valve ball, valve seat, connecting ring, spacer ring, drawing the body head is formed by connecting, it is characterized in that between connecting ring and spacer ring, spacer ring and draw joint ring is housed respectively between the body head, draw on the outer wall of body head the temperature control jump ring is housed, on the outer connecting cylinder inwall jump ring groove is arranged, the draining gate ring is equipped with in pump valve core assembly bottom in the outer connecting cylinder, the draining gate ring is by the locking of the fixedly shear pin on the outer connecting cylinder inwall, baffle ring is equipped with in outer connecting cylinder bottom, and the bottom of connecting cylinder is provided with the draining hole outside.
Outer connecting cylinder upper and lower end car respectively has box and pin thread, and the upper end links to each other with the oil well pump pump barrel, and the lower end is connected with oil pipe.Baffle ring and outer connecting cylinder bottom screwed connection.
Operating principle of the present utility model is that outer connecting cylinder upper end is linked to each other with the oil well pump pump barrel, the lower end is with after oil pipe links to each other, with tubing string precalculated position in the well together, caber in the oil pipe is ignited perforating gun, then, be lowered to pressure gauge in the oil pipe and carry out pressure test, trip out pressure gauge after, drop into the pump valve core in the oil pipe, and suppress 10MPa from oil pipe, the pump valve core is delivered in the outer connecting cylinder, and at this moment, the draining gate ring is withstood in the body head lower end of drawing of pump valve core, can not continue descending, pump valve core connecting ring, spacer ring and draw joint ring between body makes the sealing of pump valve core and outer tube inner wall, and the pressure of top oil pipe can not pass to the bottom, draw the temperature control jump ring on the body simultaneously, flexural deformation under the well temperature effect snaps in the jump ring groove of urceolus, makes the pump core can not be up, can descend pump plunger and sucker rod then, put into production.
When needs trip out flow string, suppress power 18MPa from oil pipe, at this moment, the fixedly shear pin of draining gate ring is cut off, under pressure, it is descending that the pump valve core promotes the draining gate ring, abdicates the draining hole on the outer connecting cylinder, liquid in the oil pipe of top is discharged in the well from the draining hole, reaches the draining purpose.
