Description

The linkage of a kind of hydraulic cylinder and well head
Technical field
The utility model relates to oil exploration equipment, specifically the linkage of a kind of hydraulic cylinder and well head.
Background technology
Along with deepening continuously of oil field development, the exploitation of LOW PERMEABILITY RESERVOIR, nontraditional reservoir increases year by year, and oil-water well takes pressure break, acidifying oil reservoir modification measures mostly, is the technical way of oil-water well increasing yield and injection.First open flow discharge opeing is carried out after fracture in oil and water wells acidifying measure, take the manually row of helping afterwards, oil well needs to install oil pumper, connect flow process etc., turns length of finding time, well is not owing to having Surface power drive equipment, adopt gas lift liquid drainage, working procedure multipaths is complicated more, causes and turns length of finding time, working fluid is finally caused to be detained stratum, the row of returning not in time, causes formation contaminant, affects oil-water well measure effect.
Summary of the invention
The purpose of this utility model is the linkage providing a kind of hydraulic cylinder and well head, should ensure that hydraulic cylinder is connected fast with well head and underground sucker rod, also will realize the sealing with well head, turns the object of taking out after reaching fracture in oil and water wells acidifying measure fast.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, the linkage of a kind of hydraulic cylinder and well head, comprise hydraulic cylinder, go out four-way junction of oil, described go out four-way junction of oil be arranged on thousand type fracture well heads, and hydraulic cylinder is arranged on out above four-way junction of oil, described hydraulic cylinder stretches into out four-way junction of oil successively by the piston rod of therein and thousand type fracture well heads inside is connected with sucker rod.
Described hydraulic cylinder and go out connecting fluid cylinder pressure bearing between four-way junction of oil, adopt flange arrangement bottom hydraulic cylinder, be bolted with hydraulic cylinder bearing upper flange end face, at hydraulic cylinder rest base, well head seal box is installed, hydraulic cylinder piston rod, through hydraulic cylinder bearing, stretches out from wellhead sealing box.
Describedly go out also to be connected with adapter flange between four-way junction of oil and thousand type fracture well heads.
Described piston rod is by hanger connecting with pumping rod.
Described hanger mainly comprises connector, and hanger connector two ends are internal thread, and connects bar head and the sucker rod of hydraulic cylinder piston rod respectively by internal thread.
The junction of described hanger and piston rod and sucker rod is provided with locking cap, by locking cap screw-threaded coupling.
Compared to prior art, the utility model has following beneficial effect:
The utility model is used for prospect pit and oil-water well discharge opeing, is particularly useful for oil-water well quick fluid-discharge after fracture acidizing measure.Flange arrangement is adopted bottom Barrel of Hydraulic Cylinders, supporting special wellhead assembly is directly connected with thousand type fracture well heads, need not change well head and realize turning fast taking out, shorten the time that working fluid is detained in the earth formation after fracture in oil and water wells acidifying measure, reduce formation contaminant, extend measure effect.
Accompanying drawing explanation
Fig. 1 is the linkage schematic diagram of a kind of hydraulic cylinder of the utility model and well head.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
With reference to accompanying drawing 1, the linkage of a kind of hydraulic cylinder and well head, comprise hydraulic cylinder 1, go out four-way junction of oil 4, described go out four-way junction of oil be arranged on thousand type fracture well heads 6, and hydraulic cylinder is arranged on out above four-way junction of oil, described hydraulic cylinder stretches into out four-way junction of oil successively by the piston rod of therein and thousand type fracture well heads inside is connected with sucker rod 9.Hydraulic cylinder and go out connecting fluid cylinder pressure bearing 2 between four-way junction of oil, adopt flange arrangement bottom hydraulic cylinder, be bolted with hydraulic cylinder bearing upper flange end face, at hydraulic cylinder rest base, well head seal box is installed, hydraulic cylinder piston rod, through hydraulic cylinder bearing, stretches out from wellhead sealing box 3.Go out between four-way junction of oil and thousand type fracture well heads and be also connected with adapter flange 5.Piston rod is by hanger connecting with pumping rod.Hanger mainly comprises connector, and hanger connector two ends are internal thread, and connects bar head and the sucker rod of hydraulic cylinder piston rod respectively by internal thread.The junction of hanger and piston rod and sucker rod is provided with locking cap, by locking cap screw-threaded coupling.
