The effect is as follows: the oil extraction device is suitable for oil extraction of two sets of oil layers in a vertical well or a directional well, is simple in structure, simple and applicable to operation and low in cost, and avoids a large amount of test work by adopting a single-pump constant-pressure separate extraction technology.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of branch of two-layer exploitation that is applicable to is adopted the tubing string that polyblends.
Background technology
At present, domestic layering oil production technology mainly contains separate extracting pump oil recovery and the oil production by layer of single pump level pressure.Separate extracting pump is made up of last pump and following pump, and flow string is mainly separate extracting pump and packer (Y221 or Y211), and the crude oil of last oil reservoir, time oil reservoir enters separate extracting pump by passage separately, realizes two-layer separate zone production; But the subject matter that exists is that the pump housing is long, complex structure, and pump detection period is short; The oil production by layer of single pump level pressure mainly is made of conventional pump and level pressure production mandrel, and core component is the level pressure production mandrel, by the opening pressure control high pressure zone of design level pressure production mandrel, the production capacity of performance low pressure layer.This The Application of Technology needs accurately to grasp the strata pressure of each payzone, produces stream pressure data, has increased the test job amount, and in addition, whether the level pressure production mandrel is opened in the down-hole also is difficult to judge.
The utility model content
The purpose of this utility model is: provide a kind of branch of two-layer exploitation that is applicable to adopt the tubing string that polyblends, at the two-layer oil well of exploitation simultaneously, adopt downhole tools compositions such as conventional pump, shunting pipe nipple and ball-and-seat to divide to adopt and mix out flow string, make downhole tool simple in structure, reduce cost, simple to operate.And can realize separate zone production, solve interlayer interference.
The technical solution adopted in the utility model is: the branch that is applicable to two-layer exploitation is adopted the tubing string that polyblends, mainly adopting pipe nipple, packer, ball-and-seat, screen casing and plug by oil pipe, sucker rod, oil well pump, branch forms, be with oil pipe in the sleeve pipe, oil well pump and sucker rod are arranged in the oil pipe, the sucker rod lower end is connected with oil well pump, the lower end of oil well pump is connected with branch by oil pipe and adopts pipe nipple, divide the lower end of adopting pipe nipple to be connected with packer by oil pipe, there is ball-and-seat the packer lower end, the lower end of ball-and-seat is connected with screen casing by oil pipe, and the lower end of screen casing is connected with plug by oil pipe.
Dividing to adopt has two passes in the pipe nipple, a passage is an axial passage, and axial passage is a clear opening, and axial passage UNICOM divides adopts the pipe nipple upper and lower end, and the crude oil that axial passage can make branch adopt the pipe nipple bottom flows into and divides the top of adopting pipe nipple.Another passage is a bypass passageways, and bypass passageways is made up of lateral aperture and upright opening, lateral aperture and upright opening UNICOM, and the opening part of lateral aperture is adopted at branch on the outer wall of pipe nipple, and the opening part of upright opening is adopted at branch on the upper surface of pipe nipple, and one way valve is arranged in upright opening.One way valve can prevent that fluid from pouring in down a chimney.Bypass passageways can make the crude oil of oil pipe outside flow into the top that branch is adopted pipe nipple.
The beneficial effects of the utility model: the utility model is applicable to that the branch of two-layer exploitation adopts the tubing string that polyblends, tubular column structure is simple, the straight well or the directional well that are adapted to two cover reservoir exploitations recover the oil, promptly avoid using the labyrinth of separate extracting pump, avoided adopting single pump level pressure branch to adopt a large amount of test job of technology again.And it is simple to operate, suitable, with low cost.
Description of drawings
Fig. 1 is that the utility model is applicable to that the branch of two-layer exploitation adopts the tubular column structure generalized section of polyblending.
Among the figure, 1. sleeve pipe, 2. oil pipe, 3. sucker rod, 4. oil well pump 5. minute is adopted pipe nipple, 6. packer, 7. ball-and-seat, 8. screen casing, 9. plug is 10. gone up oil reservoir, 11. times oil reservoirs.
The specific embodiment
Embodiment 1: adopting the tubing string that polyblends with a branch that is applicable to two-layer exploitation is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model is applicable to that the branch of two-layer exploitation adopts the tubing string that polyblends, mainly adopt pipe nipple 5, packer 6, ball-and-seat 7, screen casing 8 and plug 9 and form by oil pipe 2, sucker rod 3, oil well pump 4, branch, oil pipe 2 is arranged in the sleeve pipe 1, oil well pump 4 and sucker rod 3 are arranged in the oil pipe 2, sucker rod 3 lower ends are connected with oil well pump 4, and the lower end of oil well pump 4 is connected with a branch by oil pipe 2 and adopts pipe nipple 5.
Divide and to adopt pipe nipple 5 and be the cylinder bodily form, in two passes is arranged, a passage is an axial passage, axial passage is a clear opening; Another passage is a bypass passageways, bypass passageways is made up of lateral aperture and upright opening, lateral aperture and upright opening UNICOM, and the opening part of lateral aperture is adopted on the outer wall of pipe nipple 5 at branch, the opening part of upright opening is adopted at branch on the upper surface of pipe nipple 5, and an one way valve is arranged in upright opening.
Dividing the lower end of adopting pipe nipple 5 to connect one has packer 6, and it is Y221 that packer 6 is selected model for use, and the pressure that sets is 6t.The position of packer 6 is between last oil reservoir 10 and following oil reservoir 11.
