Abstract
The invention relates to a pressurizing and pushing device of a sleeve pipe. In the pressurizing and pushing device, an upper connector is connected with the upper part of an outer barrel, the lower part of the outer barrel is connected with a lower connector, a lane liquid-transmitting connector is installed in the outer barrel, the lower part of the lane liquid-transmitting connector is connected with a cylinder sleeve, a large piston is installed in the cylinder sleeve, a small piston is installed in the lower connector, a large piston seal ring is installed between the large piston and the cylinder sleeve, a small piston seal ring is installed between the small piston and the lower connector, the outer barrel is provided with an inlet hole, the lane liquid-transmitting connector is provided with a radial hole, a channel and a vertical communication hole, the lower part of the large piston is provided with a hollow cavity, and an annular channel is arranged between the cylinder sleeve and the outer barrel. When the sleeve pipe is pressurized from the inside, the upper end of the large piston and the lower end of the small piston bear the pressure of the sleeve pipe, the lower end surface of the large piston bears the pressure in an oil pipe, and the pressure of the sleeve pipe is larger than the pressure of the oil pipe, so that a force for pushing the pistons downwards can be produced to provide a push force to underground equipment so as to enable the equipment to work. Therefore, the invention can produce the downward push force by pressurizing the sleeve pipe outside the oil pipe.
Description
One, technical field
The invention belongs to the well workover of down-hole, oil field, oil production equipment, is pressurizing and pushing device of sleeve pipe.
Two, background technology
The underground equipment that has need be suppressed the downward thrust of generation and could work on hydraulic means; Suppressing the device that produces downward thrust at present all is in oil pipe, to suppress to produce downward thrust; When having blowout hookup on the tubing string; Suppress in the oil pipe and just can not transfer the pressure on the hydraulic means, underground equipment can't be worked.
Three, summary of the invention
The purpose of this invention is to provide a kind of pressurizing and pushing device of sleeve pipe, can in the sleeve pipe of oil pipe outside, suppress the downward thrust of generation.
The objective of the invention is to realize like this: be made up of top connection, shunting biography liquid joint, big piston sealing ring, big piston, valve piston, cylinder sleeve, urceolus, valve piston sealing ring, lower contact, top connection is connected with urceolus top, and the urceolus bottom is connected with lower contact; The shunting passes the liquid joint and is installed in the urceolus internal upper part, and the shunting passes liquid joint bottom and is connected with cylinder sleeve, and big piston is installed in the cylinder sleeve; Big piston is in the shunting and passes under the liquid joint, and the big piston outer wall cooperates with inboard wall of cylinder liner, and valve piston is installed in the lower contact; The valve piston outer wall cooperates with the lower contact inwall, and the big piston sealing ring is installed between big piston and the cylinder sleeve, is used to seal the gap between big piston and the cylinder sleeve; The valve piston sealing ring is installed between valve piston and the lower contact, is used to seal the gap between valve piston and the lower contact, on urceolus, be with hole; On the biography liquid joint of shunting, be provided with radial hole, pass on the liquid joint in the shunting and be provided with passage, pass on the liquid joint in the shunting and be provided with vertical linked hole; Cavity is arranged at the big piston bottom, between cylinder sleeve and the urceolus annulus access is arranged, and enters hole, radial hole, passage and communicates; Passage communicates with the big piston upper surface; Top connection is a hollow structure, and top connection, vertical linked hole, annulus access, cavity communicate, and big piston, valve piston are formed one.
The invention has the beneficial effects as follows: when in sleeve pipe, suppressing, casing pressure is born in big piston upper end, valve piston lower end, and the oil pipe internal pressure is born in the big piston lower surface; The area that promptly bears casing pressure equals to bear the area of tubing pressure, and casing pressure promotion big piston is downward, and tubing pressure promotes big piston upwards; And casing pressure is higher than tubing pressure; So, can produce the downward power of piston that promotes, make its work for underground equipment thrust; Therefore, the present invention can suppress the downward thrust of generation in the sleeve pipe of oil pipe outside.
Four, description of drawings
Accompanying drawing is the assembling full sectional view of the embodiment of the invention.
Five, the specific embodiment
Following first embodiments of the present invention are described with reference to the accompanying drawings.
Be made up of top connection 1, shunting biography liquid joint 2, big piston sealing ring 3, big piston 4, valve piston 5, cylinder sleeve 6, urceolus 7, valve piston sealing ring 8, lower contact 9, top connection 1 is connected with urceolus 7 tops, and urceolus 7 bottoms are connected with lower contact 9; The shunting passes liquid joint 2 and is installed in urceolus 7 internal upper parts, and the shunting passes liquid joint 2 bottoms and is connected with cylinder sleeve 6, and big piston 4 is installed in the cylinder sleeve 6; Big piston 4 is in the shunting and passes under the liquid joint 2, and big piston 4 outer walls cooperate with cylinder sleeve 6 inwalls, and valve piston 5 is installed in the lower contact 9; Valve piston 5 outer walls cooperate with lower contact 9 inwalls, and big piston sealing ring 3 is installed between big piston 4 and the cylinder sleeve 6, are used to seal the gap between big piston 4 and the cylinder sleeve 6; Valve piston sealing ring 8 is installed between valve piston 5 and the lower contact 9, is used to seal the gap between valve piston 5 and the lower contact 9, on urceolus 7, be with hole 10; On shunting biography liquid joint 2, be provided with radial hole 11, pass on the liquid joint 2 in the shunting and be provided with passage 13, pass on the liquid joint 2 in the shunting and be provided with vertical linked hole 12; Cavity 14 is arranged at big piston 4 bottoms, between cylinder sleeve 6 and the urceolus 7 annulus access 15 is arranged, and enters hole 10, radial hole 11, passage 13 and communicates; Passage 13 communicates with big piston 4 upper surfaces; Top connection 1 is a hollow structure, and top connection 1, vertical linked hole 12, annulus access 15, cavity 14 communicate, and big piston 4, valve piston 5 are formed one.
When going into the well, the present invention is connected on the underground equipment, top connection 1 top is connected with tubing string.In sleeve pipe, suppress, hydraulic pressure reaches big piston 4 upper surfaces from entering hole 10, radial hole 11, passage 13, because; Big piston 4 upper surfaces, casing pressure is born in valve piston 5 lower surfaces, and tubing pressure is born in big piston 4 lower surfaces; Because of casing pressure is higher than tubing pressure; This pressure differential promotes big piston 4, valve piston 5 is descending, makes underground equipment work, realizes the object of the invention.
