At present, above-mentioned test adopts water tanker to add water usually, the mode of cementing truck pressure testing, not only equipment volume is big, and is inapplicable in many instances, and above-mentioned test does not have continuity, serious waste of resources, pressure testing expense be than higher, even sometimes because of not guaranteeing that the time of using cars delays production.
(3) summary of the invention
Therefore, the utility model provides a kind of cost low at the deficiency of present prior art in well in operation pressure testing field, and pressure testing is effective, the well in operation pressure testing device of compact conformation.
The technical solution adopted in the utility model is:
The utility model well in operation pressure testing device, it comprises high pressure pressure testing system and low pressure water-feeding system, wherein the latter comprises water pot, and be used for the water pump of water, the low pressure pipeline of attaching troops to a unit, and insert blowout preventer by joint with a plurality of interfaces, and be included in described joint low pressure pipeline access port serial connection commutation ball-and-seat and with the vent valve of this system matches; Described high pressure pressure testing system comprises water tank, is used for the ram pump of water and the pressure piping of attaching troops to a unit, this pressure piping inserts an interface of described joint, to be used for the pressure testing of completion tubular column, perhaps insert the last interface of the four-way valve under the blowout preventer, to be used for the pressure testing of blowout preventer or oil pipe stopcock.
Well in operation pressure testing device basis based on technical solutions of the utility model is to need the bigger pressure testing occasion of the water yield, adopt the low pressure water-feeding system, after being full of water, utilize the high pressure pressure testing system to exert pressure again, two systems can change fast, than existing scheme, have characteristics easy and simple to handle, and easier voltage stabilizing can obtain reasonable pressure testing effect.The commutation ball-and-seat is adopted in its conversion, and is not only simple in structure, and has the fast characteristics of reaction velocity.
On the other hand, for smaller system, such as the pressure testing of blowout preventer or oil pipe stopcock, can only use on the high pressure pressure testing system water to finish pressure testing simultaneously, its whole process only is the variation of piping method and the shutoff of some mouths of pipe, and speed is fast, the high easy operating of efficient.
Adopt vent valve can guarantee the completion tubular column fills with water, deaeration is easy to pressurize, is more suitable for using in the scene.
Above-mentioned well in operation pressure testing device, described high pressure pressure testing system are provided with and are used to detect the tensimeter of pressure of fetching water.
Described ram pump water delivering orifice is provided with ball-and-seat.
Described vent valve is connected on the interface of described joint.
The flange of the last interface of described four-way valve is provided with a pressure testing flange that is used to insert described pressure piping.
Described water pump freeing port is provided with a valve.
(4) description of drawings
Below in conjunction with Figure of description the technical solution of the utility model is further described, makes those skilled in the art better understand the utility model, wherein:
Fig. 1 is a kind of user mode figure (completion tubular column pressure testing) of the utility model well in operation pressure testing device embodiment.
Fig. 2 shows blowout preventer pressure testing synoptic diagram on the four-way.
Among the figure: 1, clip, 2, vent valve, 3, joint, 4, the commutation retaining valve, 5, high pressure connection, 6, low pressure pipeline, 7, pressure piping, 8, tensimeter, 9, egg idea, 10, ram pump, 11, handle, 12, water tank, 13, water pot, 14, valve, 15, water pump, 16, electrical control cubicles, 17, pressure testing flange, 18, four-way valve, 19, sleeve valve, 20, jackscrew, 21, blowout preventer, 22, flange.
(5) embodiment
Below in conjunction with Figure of description the technical solution of the utility model is made exemplary illustration:
Figure of description 1 shows the state reference map of completion tubular column pressure testing, this pressure testing device comprises high pressure pressure testing system and low pressure water-feeding system, wherein the latter comprises water pot 13, and be used for the water pump 15 of water, the low pressure pipeline 6 of attaching troops to a unit, and the joint by having a plurality of interfaces 3 inserts blowout preventers 21, and be included in described joint low pressure pipeline access port serial connection commutation ball-and-seat 4 and with the vent valve 2 of this system matches; Described high pressure pressure testing system comprises water tank 12, is used for the ram pump 10 of water and the pressure piping 7 of attaching troops to a unit.In the use, the retaining valve of control commutation is earlier connected low pressure pipeline, and to the completion tubular column water-filling, and the unlatching vent valve queues, until being full of water, the high pressure pressure testing system is connected in control commutation retaining valve action then, the handle 11 of operation ram pump continues to add water, pressure testing gradually to water-filled completion tubular column.
