Abstract
The utility model relates to technical field of horizontal well sand-blasting operation, in particular to an efficient jet flushing device for a horizontal well sand-blasting construction pipe column. A shunting device of the efficient jet flushing device comprises an inner ring and an outer ring; a channel is reserved between the inner ring and the outer ring, and the inner ring and the outer ring are connected through a connecting piece; the lower end of an upper joint is connected with the outer ring; the lower end of the inner ring is connected with a pipe body; the lower end of the pipe body is cut into an oblique point; the outer wall of the upper wall of the pipe body is connected with an inner conical pipe; the lower end of the outer ring is connected with an outer conical pipe; the taper of the outer conical pipe is smaller than that of the inner conical pipe; an overflow channel is reserved between the outer conical pipe and the inner conical pipe. By adopting the efficient jet flushing device, forced jet flow in a horizontal direction and an obliquely-lateral direction can be generated, horizontal sand-blasting drilling advancement is quick, a;; hard deposit sand left on the inner wall of a horizontal well segment casing can be flushed by the strong lateral impact force, and the formation of a sand bridge by an oil well after sand blasting is avoided.
Description
Technical field:
The utility model relates to a kind of horizontal well sand washing operation technique field, particularly the efficient jet douche device of a kind of horizontal well sand washing operating tool string.
Background technology:
The sand washing that existing horizontal well sand washing is used tiltedly point is simple in structure, just before Φ 73 oil pipes of 40cm length, cut an oblique point, can only produce horizontal thrust, can not produce enough side direction impulse forces and some are trapped in to long-pending sand harder on net horizontal section internal surface of sleeve pipe all rinse well, this produces a plurality of sand bridges of quick formation for oil well again and leaves hidden danger.Therefore, design the efficient jet douche device of a kind of New Horizontal Well sand washing job execution tubing string particularly important.
Utility model content:
The technical problems to be solved in the utility model is to provide the efficient jet douche device of a kind of horizontal well sand washing operating tool string, this device has been realized can generation level and the oblique strong kick jet water course of side direction both direction, not only horizontal sand washing drilling depth is fast, and strong side direction impulse force can be trapped in some long-pending sand harder on net horizontal section internal surface of sleeve pipe all to rush Xian clean, avoid after sand washing oil well regeneration to produce and form sand bridge.Overcome the oblique point of existing sand washing and can not produce side direction impulse force, caused oil well after sand washing to produce again the deficiency that easily forms fast a plurality of sand bridges.
Technical solution adopted in the utility model is: the efficient jet douche device of a kind of horizontal well sand washing operating tool string, comprises top connection and part flow arrangement; Part flow arrangement comprises interior ring and outer shroud, between interior ring and outer shroud, leave passage and connect by connector, top connection lower end connects outer shroud, interior ring lower end connects body, body lower end is slit into inclined point shape, and body upper end outer wall connects inner conical pipe, and outer shroud lower end connects male-tapered pipe, the tapering of male-tapered pipe is less than inner conical pipe, between male-tapered pipe and inner conical pipe, leaves flow channels.
The beneficial effects of the utility model are: the utility model can produce the strong kick jet water course of level and oblique side direction both direction, not only horizontal sand washing drilling depth is fast, and strong side direction impulse force can be trapped in some long-pending sand harder on net horizontal section internal surface of sleeve pipe all to rush Xian clean, avoid after sand washing oil well regeneration to produce and form sand bridge.
Accompanying drawing explanation:
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.
Fig. 2 is that the A-A of Fig. 1 is to sectional drawing.
The specific embodiment:
As shown in Figure 1 and Figure 2, the efficient jet douche device of a kind of horizontal well sand washing operating tool string, comprises top connection 1 and part flow arrangement 2; Part flow arrangement 2 comprises interior ring 6 and outer shroud 7, between interior ring 6 and outer shroud 7, leave passage and connect by connector 8, top connection 1 lower end connects outer shroud 7, interior ring 6 lower ends connect body 3, body 3 lower ends are slit into inclined point shape, and body 3 upper end outer walls connect inner conical pipe 4, and outer shroud 7 lower ends connect male-tapered pipe 5, the tapering of male-tapered pipe 5 is less than inner conical pipe 4, between male-tapered pipe 5 and inner conical pipe 4, leaves flow channels.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
