Abstract
The utility model discloses a quick-assembly well controlling blow-out preventer, which is composed of a lifting short joint, a high-pressure plug valve, a flange press cover and an oil pipe joint, wherein, the flange press cover is connected with the high-pressure plug valve, the upper end of the high-pressure plug valve is connected with the lifting short joint through screw threads, the lower end of the flange press cover is provided with the oil pipe joint through screw threads, and the side face of the flange press cover is provided with a handle. When oil wells happen blowout, the utility model can effectively and rapidly subdue the blowout so as to avoid the hidden dangers of environmental pollution and safety accident which are caused by the blowout. The utility model has the advantages of simple structure, rapid installation, convenient operation, etc.
Description
Technical field
The utility model relates to a kind of blowout hookup, belongs to down-hole workover treatment aid.
Background technology
Underground work divides two kinds of light maintenance, overhauls, big well workover is generally based on big, long in time limit wells of difficulty of construction such as salvaging, sidetrackings, are furnished with various well head shut-in well devices during operation, and underground work is generally based on light maintenance, duration 2-3 days, because strata pressure instability, the reason of the difficult grasp of rule etc., blowout very easily takes place in the workover treatment process, and also is not exclusively used in the supporting wellhead assembly of minor repair well at present, thereby when the minor repair well operation, the time have blowout to take place, bring potential safety hazard to production, increased operating cost, polluted peripheral environment.
Summary of the invention
The purpose of this utility model is exactly to change the phenomenon that minor repair well does not have special-purpose blowout hookup, and a kind of ready-package well control blowout hookup is provided.
The purpose of this utility model is achieved in that ready-package well control blowout hookup is made up of lifting sub, high pressure plug valve, flange gland, oil connection, the flange gland is connected with the high pressure plug valve, high pressure plug valve upper end is threaded with lifting sub, flange gland lower end screw thread is connected with oil connection, and flange gland side is provided with handle.
The utility model can be subdued blowout fast and effectively when an oil well blew out, thereby environment pollution and the security incident hidden danger of avoiding blowout to bring have advantages such as simple in structure, quick for installation, easy to operate.
Description of drawings
Fig. 1: the utility model structural representation; Fig. 2: the utility model vertical view;
Among the figure: 1-lifting sub, 2-high pressure plug valve, 3-flange gland, 4-handle, 5-oil connection;
The specific embodiment
As shown in Figure 1 and Figure 2, ready-package well control blowout hookup is made up of lifting sub 1, high pressure plug valve 2, flange gland 3, oil connection 5, flange gland 3 is connected with high pressure plug valve 2, high pressure plug valve 2 upper ends are threaded with lifting sub 1, flange gland 3 lower end screw threads are connected with oil connection 5, and flange gland 3 sides are provided with handle 4.The effect of lifting sub 1 is to promote, transfer tubing string and blowout hookup; The effect of high pressure plug valve 2 is that sealing blocking-up oil pipe inner fluid flows; The effect of flange gland 3 is by steel ring and steel ring slot sealing oil pipe and sleeve pipe annular space; The effect of oil connection 5 is to connect tubing string and blowout hookup in the well, makes that tubing string becomes one in blowout hookup and the well, prevents in the oil pipe and oil jacket annular space liquid mobile thereby reach, and plays the purpose of blowout prevention.
Remove in the oil pipe process, when needs are prevented spraying construction, at first according to present OIH pipe standard, connect oil connection 5, two people catch handle, lift blowout hookup, oil connection 5 screw threads are aimed at OIH pipe box cupling to be tightened, elevator is accomplished fluently at 1 place at lifting sub, with working rig upper lifting pipe post and blowout hookup, slowly transfers tubing string the steel ring slot of flange gland is alignd with well head, tighten the screw on the flange gland 3, the well control blowout hookup is good and sound, closes high pressure plug valve 2, can reach the purpose that control oil pipe and cover pipe fluid flow.
