Abstract
The invention relates to a pressure test device for an oil field pumping device. The pressure test device for the oil field pumping device can be used for simulating the permeating state of the stratum, implementing the machine testing operation under pressure of equipment and verifying the type condition of the oil field pumping device. The top of a valve body is provided with a valve nozzle, and the valve body is internally provided with a tip and a valve core; a gap is reserved between the tip and the valve core, and the size of the gap can be controlled by the valve core; the gap is used for limiting the pass degree of water flow which passes through the gap, so that stratum with various permeating states can be simulated, and corresponding pressure can be generated by pumping of the equipment. The pressure test device for the oil field pumping device is convenient in processing and simple to install and operate, and easily-damaged parts are simple in processing and convenient to replace, so that the difficulty and the cost of production and operation can be greatly reduced.
Description
Technical field
The present invention relates to the pressure testing device of a kind of oil field pumping-in equipment, can be used for simulated formation infiltration state, the test-run a machine operation with pressure of facilities and equipments, the pattern situation of checking oil field pumping-in equipment.
Background technology
The various equipment toward down-hole infusion that now use in oil field need to carry out test-run a machine operation aborning and after use procedure maintenance.The different meetings of penetration degree because of stratum during this kind equipment work produce corresponding pressure, leaned against during test-run a machine in the past and a plurality of pressure regulator valves are installed on outlet line are produced step by step pressure and simulate toward the operating mode of stratum infusion, complicated operation is loaded down with trivial details, and volume is large, parts are many, produce with installation cost high.And its consumable accessory complex structure, changes inconvenience, and maintenance cost is high.
?
Summary of the invention
In order to overcome the deficiencies in the prior art, to reduce task difficulty and reduce processing and maintenance cost, the invention provides a kind of oil field pumping-in equipment pressure testing device.
The technical solution adopted for the present invention to solve the technical problems is: valve nozzle (1), top (3), spool (4) are installed in valve body (2) successively; the outer protective sleeve (5) of installing of valve body (2); top (3), valve nozzle leave gap between (1); and can pass through spool (4) and control size; be used for limiting current by time pass through degree; simulate the stratum of various infiltration states, the equipment infusion of making produces corresponding pressure.Easy to process, installation and simple to operate, consumable accessory processing is simple, replacing is convenient, has greatly reduced difficulty and the cost of production and operation.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention
1-valve nozzle in figure, 2-valve body, 3-are top, 4-spool, 5-protective sleeve.
The specific embodiment
As shown in the figure: valve body (2) front end is installed valve nozzle (1), spool (4) packs into from valve body (2) other end, and top (3) are headed into the interior valve nozzle of valve body (2) (1) position, between valve nozzle (1) and top (3), leave gap and can carry out adjusting size by the advance and retreat of spool (4).The liquid of equipment infusion, through valve nozzle (1), by the gap between valve nozzle (1) and top (3), is discharged from the opening of valve body (2) sidewall.Can simulate the stratum of various infiltration states, the equipment infusion of making produces corresponding pressure.Protective sleeve (5) is installed in valve body (2) rear end, can control the adjustable range of top (3), increases controllability, safety.Valve nozzle (1), protective sleeve (5) are connected use and are threaded with valve body (2), easy removal.Simple in structure, easy to process by the flimsy valve nozzle of water impact (1), top (3).The screw thread of valve body (2) front end outside is connected with the grout outlet of pumping-in equipment, and can be processed into the external screw thread of sizes, thereby meets connection and the use of various forms oil field pumping-in equipment.
Claims (2)
1. an oil field pumping-in equipment pressure testing device; it comprises valve nozzle (1), valve body (2), top (3), spool (4), protective sleeve (5); it is characterized in that: valve nozzle (1), top (3), spool (4) are installed in valve body (2) successively; the outer protective sleeve (5) of installing of valve body (2), top (3), valve nozzle leave gap between (1).
2. a kind of adjustable jet formula solution mixing arrangement according to claim 1, is characterized in that: valve body (2) is processed with external screw thread and is connected with pumping-in equipment grout outlet.
