Abstract
An eccentric oil pipe hanging device mainly solves the problem that the conventional hanging device lacks a test annulus and is characterized in that a large four-way valve (1) is provided with an oil pipe hanger (2); an eccentric through hole (3) for being connected with an oil pipe and an eccentric test hole (4) are formed in the oil pipe hanger (2); the lower end of the large four-way valve (1) is placed in an stepped hole of a sleeve joint (5); semicircular grooves corresponding to each other are formed in the lower end of the large four-way valve (1) and the stepped hole in the radial direction; a ball (6) is arranged in the semicircular grooves; a jackscrew (7) is connected to the sleeve joint (5) on the wall corresponding to the grooves; and a seal ring is arranged on the contact surfaces of the lower end of the large four-way valve (1) and the stepped hole. The eccentric oil pipe hanging device can provide a test annulus.
Description
Technical field:
The utility model relates to oil recovery field, oil field well head used suspension arrangement, especially eccentric oil pipe suspension arrangement.
Background technology:
In the oil recovery field, wellhead assembly is the visual plant that recovers the oil.And existing wellhead hookup has brought inconvenience because reasons in structure exists and lacks the problem of testing annular space to downhole testing, and some that influence oil well have the use of easy measure, are unfavorable for that these have applying of easy measure.
The utility model content:
Lack the problem of testing annular space in order to solve existing suspension arrangement.The utility model provides a kind of eccentric oil pipe suspension arrangement.This eccentric oil pipe suspension arrangement can provide the test annular space.
The technical scheme of the utility model is: this eccentric oil pipe suspension arrangement comprises big four.Big four is equipped with tubing hanger; The eccentric through-hole and the eccentric testing hole that connect oil pipe are arranged on the tubing hanger; The big four lower end places in the step hole of casing joint, and radially to semi-circular recesses should be arranged, groove is built-in with ball for big four lower end and step hole; Be connected with jackscrew on the wall of respective slot in the casing joint, big four lower end and step hole contact surface are provided with sealing ring.
The utlity model has following beneficial effect: this eccentric oil pipe suspension arrangement is owing to adopt big four to be equipped with tubing hanger; The eccentric through-hole and the eccentric testing hole that connect oil pipe are arranged on the tubing hanger; The big four lower end places in the step hole of casing joint, and radially to semi-circular recesses should be arranged, groove is built-in with ball for big four lower end and step hole; Be connected with jackscrew on the wall of respective slot in the casing joint, big four lower end and step hole contact surface are provided with ring structure.Utilize that eccentric through-hole and eccentric testing hole and big four lower end and casing joint step hole groove are built-in with ball on the tubing hanger; Thereby reach the purpose that well head rotates the test annular space; And simple in structure, this eccentric oil pipe suspension arrangement can provide the test annular space thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-big four among the figure, 2-tubing hanger, 3-eccentric through-hole, 4-eccentric testing hole, 5-casing joint, 6-ball, 7-jackscrew.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, this eccentric oil pipe suspension arrangement comprises big four 1.Big four 1 is equipped with tubing hanger 2, and the eccentric through-hole 3 and the eccentric testing hole 4 that connect oil pipe are arranged on the tubing hanger 2, produces the test annular space by eccentric through-hole 3 and eccentric testing hole 4.Big four 1 lower end places in the step hole of casing joint 5; Big four 1 lower end and step hole are radially to there being semi-circular recesses; Groove is built-in with ball 6; Be built-in with ball 6 by the semi-circular recesses of big four 1 lower end and step hole and form bearing, this eccentric oil pipe suspension arrangement can be rotated, provide the test annular space.Be connected with jackscrew 7 in the casing joint 5 on the wall of respective slot, by the rotation of jackscrew 7 control big fours 1.Big four 1 lower end and step hole contact surface are provided with sealing ring, are strengthened the sealing of 5 of big four 1 and casing joints by sealing ring.
