Description
Technical field
The utility model relates to the admission of oil well casing data and sleeve pipe oil Pithead preventing thieves instrument, particularly is that a kind of oil well can be tested the oil jacket sealing theft protection installation.
Background technology
Oilfield stolen phenomenon is mainly drained the oil based on sleeve pipe at present, at the more shallow well of liquid level, put sleeve pipe gas by opening sleeve gate, because the decline of pressure, make in the liquid level continuation and return well head, reach the purpose of stealing oil, the antitheft mode that adopts is at present: the one, and sleeve gate seals blind plate, but the stolen molecule is by hand drill perforating stolen, the generation that can't fundamentally stop the stolen phenomenon.The 2nd, regularly receive oil, start with from management, regularly receive oil, reach the purpose of losing oil less.The 3rd, the leather cup envelope, general down at first oil pipe, effect sealing oil sets annular space is realized the sealing of oil sets annular space crude oil, makes crude oil can't return ground, thereby reaches the purpose that prevents stolen.So fundamentally stopped the generation of stolen phenomenon, but casing pressure, liquid level data etc. can't be enrolled, dynamic analysis for oil-water well has lost necessary data, makes dynamic adjustment lack basic data, thereby makes oil field development macro adjustments and controls and microcosmic adjustment all be subjected to great restriction.In addition during operation team lift pipe string owing to can't put pressure, the phenomenon that exists pressure to discharge suddenly in a flash of sleeve pipe is opened in the leather cup sealed-off, and the induced flow phenomenon takes place easily, has potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, designs a kind of oil well and can test the oil jacket sealing theft protection installation.
The utility model is realized by following technical proposals:
Oil well can be tested the oil jacket sealing theft protection installation, comprising: sleeve, center-pole, driving bevel gear, passive bevel gear, power transmission bolt, central tube, intermediate sleeve, packing element, pressure bearing, set bolt, base ring.It is cylindrical shape that its oil well can be tested the oil jacket sealing theft protection installation, the central tube upper end is provided with external screw thread, the bottom is provided with the fixing base ring of set bolt, base ring top is equipped with pressure bearing, packing element, intermediate sleeve successively, the intermediate sleeve upper end is provided with internal thread and is connected with the central tube upper external screw thread, and the intermediate sleeve upper end is provided with the power transmission bolt; Passive bevel gear lower end is provided with the rectangle draw-in groove, and upper-end inner diameter is enclosed within the top of intermediate sleeve less than the lower part internal diameter, and draw-in groove blocks the power transmission bolt, is provided with transaudient pressure hole in the upper end of passive bevel gear.
Driving bevel gear and center-pole that above-mentioned oil well can be tested in the oil jacket sealing theft protection installation are one, and the center-pole termination is provided with the power hole, and jacket casing is on center-pole.
The power transmission bolt that above-mentioned oil well can be tested in the oil jacket sealing theft protection installation is 3～4.
The set bolt that above-mentioned oil well can be tested in the oil jacket sealing theft protection installation is 3～4, six lag screws in all adopting.
The rectangle draw-in groove that above-mentioned oil well can be tested the passive bevel gear lower end in the oil jacket sealing theft protection installation is 3～4.
The beneficial effects of the utility model are: novel structure, and reasonable in design, safe and reliable, easy to operate, can guarantee the test of the normal admission of casing pressure and producing fluid level, can reach the purpose that prevents the sleeve pipe stolen again, avoid the loss of oil well crude oil.
