Abstract
The utility model discloses an anti-theft and anti-dripping drilling sleeve cap which belongs to the technical field of oil exploitation. The anti-theft and anti-dripping drilling sleeve cap is characterized in that a limiting ring is fixed on an outer panel of the sleeve cap; a protective hood is arranged on the periphery of the limiting ring; a sleeve with a screw thread is matched with the protective hood via a thread; a limiting sheet is fixed inside the sleeve with the screw thread, and a rectangular rotating shaft is fixed with a separation blade through the limiting sheet. The anti-theft and anti-dripping drilling sleeve cap has the beneficial effects that the tool can be used when a hole is empty in oil-extraction workover treatment after oilfield drilling is finished, and the anti-theft and anti-dripping drilling sleeve cap can prevent litter from falling into the sleeve, can protect sleeve coupling, and also has an anti-theft function. The anti-theft and anti-dripping drilling sleeve cap has the advantages of rational structure, simple process, low cost, convenience for operation, strong practicability, first prevention and significant effect.
Description
Technical field
The utility model belongs to technical field of petroleum extraction.
Background technology
At present, after the oil drilling completion, during oil recovery workover treatment empty well; Need that the sleeve pipe in the well is carried out capping and handle, but generally all be now with crown cap through being bolted on the sleeve pipe, crown cap is very easily lost; Cause sleeve opening to damage, sleeve opening stops up, and influences subsequent production.
Summary of the invention
The purpose of the utility model is: a kind of drilling anti-fall sleeve cap of guarding against theft is provided, and it can cover the sleeve pipe mouth of pipe effectively, can't lose.
The technical scheme of the utility model is: be fixed with spacing ring in the casing cover outer panels, the spacing ring periphery is provided with protective cover, and band screw thread sleeve pipe and protective cover threaded engagement are fixed with banking stop in the screw thread sleeve pipe, and the rectangle axis of rotation passes banking stop and catch is fixed.
The beneficial effect of the utility model is: after the oil drilling completion, during oil recovery workover treatment empty well, all can use this instrument, it can prevent junk in the sleeve pipe, can also protect this casing coupling, also has anti-theft feature.Rational in infrastructure, processing is simple, and is with low cost; Easy to operate, practical; Put prevention first, effect is remarkable.
Description of drawings
Fig. 1 is that front view cuts open in the utility model structure office;
Fig. 2 is the utility model A-A ' side cross-sectional view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in Figure 1, the 1st, casing cover, the 2nd, spacing ring, the 3rd, protective cover, the 4th, screw thread sleeve pipe, the 5th, banking stop, the 6th, axis of rotation, the 7th, catch.
Casing cover 1, spacing ring 2, protective cover 3 are combined through welding; Screw thread sleeve pipe 4 passes through welding with banking stop 5, combines; Axis of rotation 6 passes through welding with catch 7, combines.Casing cover 1, spacing ring 2, protective cover 3 are combined through axis of rotation 6, catch 7 with sleeve pipe screw thread 4, banking stop 5.Its operating principle: use special spanner through axis of rotation 6 rotations; Then drive banking stop 5 and the rotation of screw thread 4 sleeve pipes; Then screw thread sleeve pipe 4 tightens together with ground casing coupling, and uses other instrument to open, and must use the spanner of special use just can open the drilling anti-fall sleeve cap of guarding against theft; Also can't in sleeve pipe, drop into other object, protect smooth and easy in the sleeve pipe.Thereby use this instrument can play the effect of antitheft, anti-junk, protective casing box cupling.
