Description
Technical field
The utility model belongs to the brill plug equipment bored and remove institute's cementing plug in petroleum industry oil gas water well, and particularly high pressure is shallow
The totally-enclosed brill plug device of layer, it is adaptable to bore except the cement plug of the oil gas water well middle-range shallow-layer position nearer from well head.
Background technology
At present, the positional distance well head of institute's cementing plug is nearer in some oil gas water wells in oil field, after long-term shut-in well, due to
The reasons such as strata pressure recovery, easily assemble high-pressure oil gas, the pressure being closed is higher in cement plug bottom, and what is had is even as high as
More than 105MPa.When these old wells repair utilization again, generally using it is conventional bore plug technique and bore remove cement plug, but on being due to
The cement setier stated in well is shallow, and drilling tool weight is too light, once high-pressure oil gas will be run into by drilling through cement plug, high-pressure oil gas moment releases
Put, drilling tool is easily flown by Jing Neigaoyading, even " launch " and go out, cause danger.There is resettlement with traditional implement with pressure
And operating cost it is high the shortcomings of.In order to prevent the generation of above-mentioned accident, current common equipment has free-standing Operating Pressure equipment,
Assist type Operating Pressure equipment, coiled tubing Operating Pressure equipment.Its implement it is main by operation power-equipment, it is derrick, anti-
Jet pipe post, injection head, the plurality of devices such as hydraulic control and additional device are constituted；Its major defect is that these equipment costs are high, knot
Structure is complicated, and equipment is huge, and migration removal of home cost is high, and operating cost is also high, it is necessary to the shortcomings of many operating personnels of configuration, such as a set of
Free-standing Operating Pressure equipment, continuous oil pipe operation equipment, 10,000,000 yuan of a set of price all up to 3-4, considerably increase production
Cost.
At present, production scene needs a kind of simple in construction, reliable operation, and the high shallow-layer of safety coefficient bores plug special equipment,
To make up the blank that shallow-layer high pressure bores plug operation.
The content of the invention
The purpose of this utility model is to provide the totally-enclosed brill plug device of high pressure shallow-layer, is that shallow-layer high pressure bores plug operation institute specially
With, it can effectively apply and control the pressure of the drill, realize that shallow-layer bores plug operation, can be achieved effective control when there is instantaneous pressure in well,
Prevent that plug tubing string is bored in well to be ejected.The input that shallow-layer bores plug operating cost is reduced, production cost is reduced.
Technical solution of the present utility model is：The totally-enclosed plug device that bores of high pressure shallow-layer includes lubricator, lubricator
Body, which is provided with down, suppresses mouth, tubular body equipped with piston assembly, lubricator upper end from bottom to top successively with above to suppress flange total
It is connected successively with conversion pipe nipple and blowout prevention nipple from top to bottom into anti-rotation assembly connection, lower end, the cylinder in anti-rotation assembly leads to
Spline housing is crossed to be connected with the leather cup branch pipe and direct-connected pipe pipe nipple above suppressed in the anti-rotary joint in flange assembly, piston assembly successively
And be connected by direct-connected pipe pipe nipple with boring plug tubing string and hydrodynamic force drilling tool；The outside of lubricator is fixed by pipeline fixed support
Plug valve and check valve, check valve is connected with plug valve, the outlet of check valve is total with above suppressing flange by above suppressing pipeline
Into on suppress mouth connection, the import of check valve and be connected by pipeline with ground pump truck, under suppress mouth and pass through pipeline and run-off
Connection, cylinder is connected with source of the gas.
Compared with prior art, remarkable result of the present utility model is：The present apparatus is simple in construction, by piston assembly and
Anti- rotation assembly all closes the direct-connected adapter pipe nipple in the present apparatus more than well head, can be high pressure resistant.By control pump truck pump pressure,
The lifting rate that discharge capacity suppresses mouth with effectively controls the pressure of the drill, realizes that safety bores plug operation.When playing lower tubular column operation, with boring plug tubing string
The direct-connected pipe pipe nipple of connection can be moved up and down in the inner chamber of the totally enclosed lubricator of the present apparatus, realize drilling with rising；It is logical
Cross the high pressure for being pumped, increasing burst in pump pressure energy Real time buffer well in good time of control pump truck.When there is instantaneous pressure, under the present apparatus
The blowout prevention nipple in portion can transfer the pressure to wellhead blowout preventer, while the water under high pressure in lubricator can be to height unexpected in well
Pressure plays cushioning effect, is that timely wellhead blowout preventer of closing leaves the time, solves brill plug tubing string and flown by Jing Neigaoyading
The problem of, it is prevented effectively from and bores that plug is prominent to meet high pressure, bore plug tubing string and be ejected risk with blowout out of control.
In addition, the present apparatus has anti-rotation assembly, when can prevent that hydrodynamic force drilling tool from normally creeping into, plug tubing string reversion is bored to close
Seal part, the as above destruction caused by the seal member such as piston cup, lower piston leather cup, packing unit, while also ensure that brill
Fill in the security of operation.
The manufacturing cost of the present apparatus is low, simple to operate, safe and reliable, production cost is effectively reduced, with fine
Using effect and significant economic benefit can be produced.
