Description
Technical field:
The utility model relates to a kind of horizontal well, high angle hole technical field, particularly the anti-pollution drainage device of a kind of horizontal well.
Background technology:
At present, also based on conventional sleeve type and releasing type bleeder, mainly there is following problem in the bleeder kind of horizontal well, high angle hole onsite application:
L, conventional sleeve type: enter special tool under needs, can also realize normal draining at straight well or little Wells, but because casing programme limit on horizontal well, high angle hole, especially be just difficult to realize normal draining when wax deposition in oil pipe or when having foreign matter.
2, releasing type: be when job execution, trips out in construction well oil pipe and cuts off bleeder pin from well head throwing sucker rod substitute after sucker rod, make oil jacket be communicated with draining.Which limits by unimpeded degree in the casing programme of horizontal well, high angle hole and oil pipe equally, and a lot of situation occurs that sucker rod substitute can not be thrown in and puts in place, cannot realize normal draining.
Utility model content:
The technical problems to be solved in the utility model is to provide the anti-pollution drainage device of a kind of horizontal well, the arrangement achieves and successfully can carry out draining operation safely, and simple to operation, can reuse, operating efficiency is high.Overcome the deficiency that existing level well bleeder can not carry out safely draining operation smoothly.
Technical solution adopted in the utility model is: the anti-pollution drainage device of a kind of horizontal well, comprises oil pipe tube connector, and oil pipe tube connector upper end is provided with thread, and oil pipe tube connector lower end is provided with lower thread, oil pipe tube connector inwall is provided with slip circular groove, moving sliding sleeve is arranged in slip circular groove and also can moves up and down in slip circular groove, slip circular groove inwall has compression annular groove, moving sliding sleeve outer wall is provided with limited ring dais, limited ring dais stretches in compression annular groove, Compress Spring is sleeved on moving sliding sleeve, Compress Spring upper end withstands on compression annular groove upper surface, Compress Spring lower end withstands on limited ring dais, oil pipe tube connector has oil leak hole, moving sliding sleeve lower end sidewall blocks oil leak hole, moving sliding sleeve lower end is provided with unidirectional gland, unidirectional gland lower end sidewall is designed to inside contract tank deck, unidirectional gland lower end inner wall has draw-in groove, inside, oil pipe tube connector lower end is provided with sucker rod connecting rod, sucker rod connecting rod upper end is designed with top connection, sucker rod connecting rod lower end is designed with lower contact, sucker rod connecting rod sidewall has compression groove, in compression groove, compression blocks is installed, limiting plate is connected outside compression blocks, limiting plate can match with draw-in groove and can be stuck in draw-in groove, spring one end is connected to inside compression groove, the spring other end is connected on compression blocks outer face.
The outer wall place that oil leak hole position is blocked in moving sliding sleeve lower end is provided with elastic sealing layer.
The beneficial effects of the utility model are: the utility model successfully can carry out draining operation safely, simple to operation, and can reuse, operating efficiency is high.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, the anti-pollution drainage device of a kind of horizontal well, comprises oil pipe tube connector 1, and oil pipe tube connector 1 upper end is provided with thread 2, and oil pipe tube connector 1 lower end is provided with lower thread 3, oil pipe tube connector 1 inwall is provided with slip circular groove 4, moving sliding sleeve 7 is arranged in slip circular groove 4 and also can moves up and down in slip circular groove 4, slip circular groove 4 inwall has compression annular groove 5, moving sliding sleeve 7 outer wall is provided with limited ring dais 8, limited ring dais 8 stretches in compression annular groove 5, Compress Spring 6 is sleeved on moving sliding sleeve 7, Compress Spring 6 upper end withstands on compression annular groove 5 upper surface, Compress Spring 6 lower end withstands on limited ring dais 8, oil pipe tube connector 1 has oil leak hole 12, moving sliding sleeve 7 lower end sidewall blocks oil leak hole 12, moving sliding sleeve 7 lower end is provided with unidirectional gland 9, unidirectional gland 9 lower end sidewall is designed to inside contract tank deck 10, unidirectional gland 9 lower end inner wall has draw-in groove 11, inside, oil pipe tube connector 1 lower end is provided with sucker rod connecting rod 13, sucker rod connecting rod 13 upper end is designed with top connection, sucker rod connecting rod 13 lower end is designed with lower contact 14, sucker rod connecting rod 13 sidewall has compression groove 16, compression blocks 15 is installed in compression groove 16, limiting plate 17 is connected outside compression blocks 15, limiting plate 17 can match with draw-in groove 11 and can be stuck in draw-in groove 11, spring 18 one end is connected to inside compression groove 16, spring 18 other end is connected on compression blocks 15 outer face.
The outer wall place that oil leak hole 12 position is blocked in moving sliding sleeve 7 lower end is provided with elastic sealing layer.The inner ring surface diameter of unidirectional gland 9 is less than the minimum inner ring surface diameter of oil pipe tube connector 1, and unidirectional gland 9 upper and lower end face is provided with oblique chamfering.The downside inlet side of draw-in groove 11 is provided with symmetrical importing sloping platform.
