Abstract
An oil field sucker rod environmental protection operation well control device. The problem of current sucker-rod pump well construction need stop between operation well control time control well difficulty is mainly solved. The method is characterized in that: the upper end of the body (1) is provided with a thin rod head (2), the center of the bottom is provided with a thin rod (5), the outer part of the thin rod (5) is provided with a sleeve (4), a ring cavity body is arranged between the sleeve (4) and the thin rod (5), and the upper end of the ring cavity body is closed; one side of the middle part of the sleeve (4) is connected with a side pipe joint (3), and the side pipe joint (3) is communicated with the annular cavity. The oil field sucker rod environmental protection operation well control device meets the well control requirement of the underground rod descending function, can quickly realize well control, improves the construction efficiency, eliminates the well site environmental pollution and safely removes the trouble.
Description
Technical Field
The utility model relates to an oil field, an oil field sucker rod environmental protection operation well control ware specifically says so.
Background
At present, the pump is examined to the sucker-rod pump well, the pole is dragged for, the pump is traded, new pump construction in the pit is one of the important means of the normal production development of guarantee oil field, all need to take out down the sucker rod string in the construction, when the construction appears that the overflow is big, the kick, or other reasons need stop between the operation well control, well control difficulty: firstly, when the screw pump well is connected with a sucker rod well control in a suspension well, the driving head motor can be seated in 20-30min, and particularly the driving head motor is difficult to seat in the case of well kick; and secondly, when the pumping unit well is connected with a pumping rod well control in a suspension well, the polished rod and the paraffin removal gate can be connected within 5-10min, the rope braid of the rope hanger is easy to twist and wind, and the well control needs longer time. The labor intensity of workers is high during construction under the working conditions, the construction efficiency is low, well site pollution and surrounding environment hidden dangers are high, and the underground operation well control construction requirements cannot be met.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of operation well control time well control difficulty that stops between current sucker rod pump well construction needs, the utility model provides an oil field sucker rod environmental protection operation well control ware, this oil field sucker rod environmental protection operation well control ware have satisfied the well control requirement of having played down-pipe effect in the pit, can realize well control fast, improve the efficiency of construction, eliminate well site environmental pollution and remove safely and suffer.
The technical scheme of the utility model is that: an environment-friendly operation well control device for an oil field sucker rod comprises a body, wherein a thin rod head is arranged at the upper end of the body, a thin rod is arranged at the center of the bottom of the body, a sleeve is arranged outside the thin rod, a ring cavity body is arranged between the sleeve and the thin rod, and the upper end of the ring cavity body is sealed; and one side of the middle part of the sleeve is connected with a side pipe joint which is communicated with the annular cavity.
The thin rod and the lower end of the sleeve are provided with external threads, and the end part of the side pipe joint is provided with internal threads.
The thin rod head is a cylindrical head with the diameter larger than that of the thin rod.
The utility model discloses following beneficial effect has: by adopting the scheme, the well control device solves the problems of difficulty and long time consumption of the original intermittent operation well control, meets the well control requirement of underground rod lifting operation, can greatly improve the construction efficiency, lightens the labor intensity of workers, and thoroughly eliminates the potential safety hazard of polluting well sites and surrounding environments.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-body, 2-thin rod head, 3-side pipe joint, 4-sleeve and 5-thin rod.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the oil field sucker rod environmental protection operation well control device comprises a body 1, wherein the upper end of the body 1 is a thin rod head 2, and the thin rod head 2 is a cylindrical head with the diameter larger than that of a thin rod. The center of the bottom of the body 1 is provided with a thin rod 5, and an external thread is processed on the thin rod 5. The outside of the thin rod 5 is provided with a sleeve 4, an annular cavity is arranged between the sleeve 4 and the thin rod 5, and the upper end of the sleeve 4 is connected with the thin rod 5, so that the upper end of the annular cavity is sealed. One side of the middle part of the sleeve 4 is connected with a side pipe joint 3, the side pipe joint 3 is communicated with the annular cavity, and the end part of the side pipe joint 3 is provided with an internal thread.
When the well control device is applied, the external thread of a thin rod 5 at the lower end is connected with a well head sucker rod, then a thin rod head 2 at the upper end is hung and clamped in a sucker rod lifting cylinder, and then the well screwing device is lifted by a workover rig, and a threaded male buckle of a sleeve 4 at the lower end of a body 1 is hermetically connected with a well head; and then, the female buckle of the side pipe joint 3 in the middle is hermetically connected with the simple gate valve, and the gate valve is closed, so that the rapid well control within 2min can be realized. The well control device can greatly improve the construction efficiency, reduce the labor intensity of workers, solve the problem that the well control is difficult and time-consuming in the original intermittent operation, meet the well control requirement of underground rod lifting operation, and thoroughly eliminate the potential safety hazard of polluting well sites and surrounding environment.
