Abstract
The utility model relates to a well completion pipe string for oil exploitation, which is especially suitable for the well completion pipe string of a horizontal well with a small well hole and a mid-short radius. Both ends of a body are provided with screw threads. The middle part of the body is cut with gaps which can be mutually engaged along the circumferential direction. A sealing joint which is vulcanized into one unit with a rubber seal is arranged in the body and is fixed by fixing bolts. Both ends of the sealing joint are provided with sealing rings. The utility model can be directly connected with the well completion pipe string, and increases the flexibility of the well completion pipe string; the well completion pipe string for oil exploitation has the advantages of simple structure, convenient operation, and low cost.
Description
The utility model relates to the completion tubular column that a kind of oil exploitation is used, and is particularly useful in the slim-hole, the Short Radius Horizontal Wells completion tubular column.
At present, on-the-spot beating inclined shaft, horizontal well, especially beating in the slim-hole, during Short Radius Horizontal Wells,, so just make drilling cost increase considerably owing to the restriction that is subjected to completion tubular column rigidity is forced to reduce build angle rate.Perhaps the build angle rate owing to the horizontal well of being beaten is bigger, and has been forced to adopt the less tubing string of diameter, thereby has brought many inconvenience for follow-up oil extraction operation.
The purpose of this utility model is to provide a kind of flexible joint that can directly be connected between the completion tubular column.
The utility model is realized in the following manner:
The two ends car of body has screw thread, and body middle part is along circumferentially cutting the seam of interlock mutually, packs into for the seal nipple of one with the rubber seal sulfuration and is fixed by thrust bolt in the body, and sealing ring is equipped with at the seal nipple two ends.
Advantage of the present utility model is and can directly be connected with completion tubular column, increases the flexibility of completion tubular column, and simple in structure, easy to use, cheap.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, the utility model comprise the two ends car by screw thread and middle part along circumferentially cut by the body 1 of the seam of interlock mutually, with rubber seal 5 sulfurations be that seal nipple 4, thrust bolt 3, the sealing ring 2,6 of one formed, seal nipple 4 is packed into fixing by thrust bolt 3 in the body 1, and sealing ring 2,6 is used between body 1 and the seal nipple 4.
Wherein there is " T " shape seam of interlock mutually at body 1 middle part along circumferential evil.
Wherein the thrust bolt on the body 13 is 3 to 5, withdraws to prevent seal nipple 4.
Wherein sealing ring 2,6 is " O " shape sealing ring, and to prevent managing inside and outside mud in seal nipple 4 and 1 channelling of body, sealing ring 2,6 also can be " T " shape sealing ring.
During work, the screw thread up and down of body 1 directly links to each other with completion tubular column.
