Abstract
The utility model relates to an oil pipe with a separation device used in oil production wells, wherein the lower end of the oil pipe is provided with a separation device and a pipe string, the separation device is connected with the lower end of the oil pipe via a pipe string connecting sleeve and the pipe string is connected with the lower end of the separation device. The utility model can accomplish separating the oil pipe in a fixed position and the pipe string via the separation device when the oil production wells are blocked in construction operation. When work layer is changed for drilling plunger operation, the utility model reduces the workload of drilling dust plunger because the material hardness of the pipe string which is connected with the pipe string sleeve is much lower than the material hardness of the oil pipe. With experiment indication, a dust plunger adopting an oil pipe can be drilled through in more than one month and a dust plunger adopting the pipe string can be drilled through in only two or three days. Therefore, the utility model not only increases the productivity of the oil wells and reduces fault time and maintenance man hours of the oil wells, but also reduces the energy consumption of drilling operation.
Description
Technical field
The utility model relates to field of petroleum exploitation, particularly relates to a kind of producing well oil pipe that has separator.
Background technology
In the prior art of oil exploitation, oil well is being annotated ash, agent is stifled, in the work progresss such as sand washing, owing to multiple reason, oil pipe is annotated dead by mortar, be that oil pipe phenomenon stuck or that be commonly called as the bar that plants flag is the accident of common generation, after taking place, accident no matter take which type of measure to remedy, leave some oil pipes always in oil well at the down-hole red dog, thereby bring very big difficulty for later construction, when junk mill equipment grinds off the oil pipe that is detained in the oil well and ash plug under adopting, generally need the time more than one month, so not only influenced the exploitation production of oil well, and cause tremendous loss for other all many-side.
Summary of the invention
The purpose of this utility model provides a kind of producing well oil pipe that has separator, pass through the technical program, at the oil pipe front end pipe string and separator are set, when the various stuck phenomenon of down-hole occurring, can oil pipe be separated with the pipe string in the precalculated position, propose oil pipe easily, make the work of annotating ash brill plug only need the time about two, three days just can finish, thereby remedied the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of producing well oil pipe that has separator, the lower end of described oil pipe is provided with separator and pipe string, described separator is connected with the lower end of oil pipe by pipe series connection cover, and described pipe string links to each other with the lower end of separator.
Described separator is made of outer tube, pin and interior cover, the lower end of described outer tube links to each other with the pipe string, the upper end of cover links to each other with pipe series connection cover in described, on the arc surface of outer tube, be provided with 2 pin holes, the bottom is provided with the hemispherical concave station in its outer tube, be provided with the groove of sealing on the pairing inner sleeve wall of pin hole, described pin is inserted in the pairing groove by pin hole.
The length of described pipe string is 60-120 rice, and is constituted by several pipe string sections, and the length of described each pipe string section is 4-10 rice, and each pipe string section is connected by pipe series connection cover and is one.
The end, lower end of described pipe string is provided with opened type pipe series connection cover, and the uncovered angle of described opened type pipe series connection cover is the 60-120 degree.
Described pipe string, pipe series connection cover and opened type pipe series connection cover are made by the non-ferrous metal soft material.
When stuck phenomenon occurring, in oil pipe, put into the obstruction ball, stop up the passage that ball stops up oil pipe, charge into gases at high pressure in the oil pipe after, under the effect of gases at high pressure, the separator upper exterior tube is pushed down, and realizes separating with oil pipe after cutting off pin.
The producing well oil pipe beneficial effect that the utility model has separator is, pass through present design, carry out construction operation when stuck phenomenon occurring at producing well, the oil pipe that is implemented in the permanent position by separator separates with the pipe string, and as long as use less strength just oil pipe can be proposed, when the change working surfaces is bored plug work, because and the material hardness of pipe series connection bunch tube is well below the material hardness of oil pipe, drill through the workload of annotating ash thereby greatly reduce, show by experiment, drilling through the time of needs more than one month time that on average drills through for the notes ash that has oil pipe, and drill through as long as two for the notes ash that adopts the pipe string, time about three days, so not only improved the productivity ratio of oil well greatly, reduce the fault time and the maintenance man-hours of oil well, and significantly reduced the energy consumption of the work that drills through.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation that separates dress in the utility model.
Among the figure, cover, 8 closed pockets, 9 pins, 10 outer tubes, 11 hemispherical concave stations, 12 stop up ball in 1 oil pipe, 2 pipe strings, 3 pipe series connection covers, 4 pipe string sections, 5 opened type pipes, 6 separators, 7.
Below in conjunction with accompanying drawing the utility model is described further.
The specific embodiment
As shown in the figure, the producing well oil pipe that has separator that the utility model relates to, the lower end of described oil pipe 1 is provided with separator 6 and pipe string 2, and described separator 6 is connected with the lower end of oil pipe 1 by pipe series connection cover 3, and described pipe string 2 links to each other with the lower end of separator 6.
