Abstract
The utility model relates to a blowout preventer for rod breakage of a screw pump well. The blowout preventer comprises a preventer cylinder (3); a preventer upper cover (1) is in threaded connection with the upper end of the preventer cylinder (3); a connection joint (6) is arranged inside the lower end of the preventer cylinder (3); the bottom surface of the preventer upper cover (1) is hinged with an overturn plate (2); a torsion spring (7) is sleeved on a hinge shaft (5); and the area of the overturn plate (2) is greater than that of an inner hole on the preventer upper cover (5). After the blowout preventer for the rod breakage of the screw pump well is used, an oil leakage accident caused by the rod breakage of the screw pump well is prevented, the oil yield is protected, environment pollution is prevented, and the labor intensity of a worker is reduced.
Description
Technical field
The utility model relates to the used a kind of blowout hookup of oil extraction in oil field field screw pump, specifically the disconnected bar preventer of a kind of screw bolt well.
Background technology
The screw pump pumping technology is used widely in our oil field, has the characteristics little, high efficiency of investing.But, in the equipment disconnected bar phenomenon of well head that also can occur suddenly in service, cause Wellhead crue oil to leak, form large-area environment pollution, need to consume a large amount of human and material resources and clear up.
Summary of the invention
In order to solve the problem that exists in the background technology; the utility model adopts a kind of screw bolt well bar preventer that breaks; after the disconnected bar preventer of screw bolt well is used; the oil spill disaster that effectively prevents the disconnected bar of screw bolt well and occur; in the protection crude output; also protect environment not contaminated, reduced post workman's labour intensity.
The technical scheme that the utility model adopts is: the disconnected bar preventer of this screw bolt well comprises the preventer cylinder, the preventer upper press cover has been threaded on the preventer cylinder, the preventer cylinder is provided with jointing in the lower end, preventer upper press cover bottom surface is hinged with turnover panel, and cover has the button spring on the jointed shaft, and the area of turnover panel is greater than the area of preventer upper press cover endoporus.
The beneficial effects of the utility model are: the use of this achievement; effectively prevented because of the disconnected series of problems that brings of bar, the rate during running that has indirectly improved pumpingh well, thus protected crude output; reduce post workman's labour intensity, had higher economic benefit and social benefit.This achievement has small investment, instant effect, easy to operate, safe characteristics, has preferably promotion prospect.
Description of drawings:
Fig. 1 is structure turnover panel schematic diagram of the present utility model.
Among the figure: 1-preventer upper press cover, 2-turnover panel, 3-preventer cylinder, 4-clamping sleeve, 5-jointed shaft, 6-jointing, 7-button spring.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: this screw bolt well bar preventer that breaks, comprise preventer cylinder 3, the preventer cylinder 3 upper ends preventer upper press cover 1 that has been threaded, preventer upper press cover 1 is equipped with packing box and packing, the preventer cylinder is provided with jointing 6 in 3 lower ends, jointing 6 inner threads are connected with clamping sleeve 4, preventer upper press cover 1 bottom surface is hinged with turnover panel 2, and cover has a button spring 7 on the jointed shaft 5, and the area of turnover panel 2 is greater than the area of preventer upper press cover 1 endoporus and less than the area of preventer upper press cover 1 external diameter.
During installation, at first the packing pressure cap of former well head is taken out, the preventer cylinder is dropped on driving head is connected pressure cap behind the well head and tighten, connect, install and again the preventer upper press cover is buckled well after firm, continue to install preventer packing, preventer packing upper press cover, with preventer the fastening location of jackscrew is installed.This moment, sucker rod passed preventer upper press cover 1 and preventer cylinder 3 endoporus, and turnover panel 2 is propped.
During the disconnected bar preventer normal operation of screw bolt well, run into well head position bar when disconnected, sucker rod is fallen in the well, and preventer turnover panel 2 rotates under the effect of spring force and down-hole pressure, be that whole sucker rod passage stops and closes with preventer upper press cover 1 endoporus envelope letter, the ejection of blocking-up oil gas.
Claims (2)
