Detailed description of the invention
By reference to the accompanying drawings with the description of the utility model detailed description of the invention, can clearly understand details of the present utility model.But detailed description of the invention of the present utility model described here, only for explaining the purpose of this utility model, and can not to be understood as by any way be to restriction of the present utility model.Under instruction of the present utility model, technician can conceive based on distortion possible arbitrarily of the present utility model, and these all should be regarded as belonging to scope of the present utility model.
With reference to shown in Fig. 1, the utility model discloses a kind of tubing string of horizontal well, horizontal well comprises straight well section and horizontal segment, horizontal well with tubing string comprise horizontal well with combined type drainage device, for connecting oil pipe 1, the horizontal well pump 3 of each mechanism.Horizontal well pump 3 is positioned at the horizontal segment of horizontal well, and horizontal well pump 3 can provide power to the fluid in horizontal well thus fluid is promoted to ground extraction.
The combined type drainage device of horizontal well comprises the shearing type oil drain device 2 of the straight well section being arranged on described horizontal well and is arranged on the hammering oil discharger 4 of horizontal segment of described horizontal well.
In the present embodiment, shearing type oil drain device 2 is arranged on horizontal well 1000-1500m straight well section place, can not occur that rod collar friction sliding sleeve 8 causes the problem opening by mistake and open in process of production.With reference to shown in Fig. 2 and Fig. 3, shearing type oil drain device 2 comprises cutting mechanism and draining mechanism.As shown in Figure 2, described cutting mechanism comprise offer the first oil leak hole the first noumenon 5, to be arranged on described the first noumenon 5 by shear pin 7 and the sliding sleeve 8 of described first oil leak hole can be blocked.As shown in Figure 3, described draining mechanism comprises cone 9, the slips 10 be set in outside described cone 9, and described slips 10 relatively described cone 9 can slide and radially expand to conflict with described sliding sleeve 8, is separated with described the first noumenon 5 to make described sliding sleeve 8.Cone 9 is connected with sucker rod, its can with sucker rod slide, and then the taper surface of cone 9 and slips 10 inconsistent, slips 10 is radially expanded.Slips 10 moves to inconsistent with sliding sleeve 8 and produces opposing force, and then effect is on shear pin 7.When the active force that the slips 10 pairs of shear pins 7 apply exceedes the maximum shear stress that shear pin 7 can bear, shear pin 7 ruptures, sliding sleeve 8 and the first noumenon 5 are separated, and now sliding sleeve 8 no longer plays to the first oil leak hole the effect of blocking, and the fluid being originally arranged in oil pipe 1 releases from the first oil leak hole.Preferably, in order to ensure the sealing when producing, the first sealing ring 6 between the first noumenon 5 and described shear pin 7, is equipped with.
