Abstract
The utility model relates to the field of open hole completion and staged fracturing processes of horizontal wells for oil and gas field exploration, in particular to a ball-locking setting ball seat, which consists of an upper joint (1), an external cylinder (2), a ball locking mechanism (3) and a ball seat (4), wherein the ball locking mechanism (3) and the ball seat (4) are arranged inside the external cylinder (2); and the ball locking mechanism (3) adopts the design of a pawl spring structure. The ball-locking setting ball seat is simple and practical, is not limited by a foreign company and is low in cost; the process requirements of the horizontal wells are met; and the defects that the existing setting ball seat matched with the open hole completion and staged fracturing process for the horizontal wells does not have an independent intellectual property and has a high application cost are overcome.
Description
Technical field:
The utility model relates to a kind of oil, gas field development horizontal well barefoot completion and staged fracturing technology field, particularly a kind of lock ball formula setting ball seat.
Background technology:
The setting ball seat of existing horizontal well barefoot completion staged fracturing process matching all from external import, is limited by offshore company, no independent intellectual property right, and the implementation cost height is applied difficulty.
The utility model content:
The technical problems to be solved in the utility model provides a kind of lock ball formula setting ball seat, and this setting ball seat has realized satisfying the horizontal well technological requirement, and is simple and practical, is not limited by offshore company, and implementation cost is low.The setting ball seat that has overcome existing level well barefoot completion staged fracturing process matching does not have independent intellectual property right, the deficiency that implementation cost is high.
Technical solution adopted in the utility model is: a kind of lock ball formula setting ball seat, form by top connection, urceolus, lock ball mechanism and ball seat; Lock ball mechanism and ball seat are installed in the urceolus, and lock ball mechanism adopts the pawl spring structure design.
The beneficial effects of the utility model are: the utility model has been owing to adopted lock ball mechanism and ball seat have been installed in structure in the urceolus, thereby has the horizontal well of satisfying technological requirement, and is simple and practical, is not limited by offshore company, and implementation cost is low.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of lock ball formula setting ball seat is made up of top connection 1, urceolus 2, lock ball mechanism 3 and ball seat 4; Lock ball mechanism 3 and ball seat 4 are installed in the urceolus 2, and lock ball mechanism 3 adopts the pawl spring structure design.
The utility model is the kit of horizontal well barefoot completion staged fracturing technology, connects with completion tubular column to be lowered to, and before lock ball mechanism 3 started, the pawl spring in the lock ball mechanism 3 was in the free state that do not stress; Open the back and by pawl spring contraction locking ball is got lodged in the ball seat 4, ball cooperates with ball seat realizes sealing.Reach the dual purpose of lock ball, sealing.
Claims (1)
1. a lock ball formula setting ball seat is made up of top connection (1), urceolus (2), lock ball mechanism (3) and ball seat (4); It is characterized in that: lock ball mechanism (3) and ball seat (4) are installed in the urceolus (2), and lock ball mechanism (3) adopts the pawl spring structure design.
