Problems solved by technology

[0010] (3) The anti-fatigue strength of the rubber tube is low. Under the action of high pressure and high temperature, the rubber tube is damaged or the seal is not tight, which will cause the packer to fail in a short time

Embodiment

[0027] Such as figure 1 As shown, the simulation test device for the packer involved in this embodiment is mainly composed of a support frame 1, a suspension device arranged on the support frame 1, and a packer 2 connected to the suspension device. The device 2 is set in the simulated oil well 3; it also includes a heating pool 4 connected to the inside of the simulated oil well 3.

[0028] The suspension device is mainly composed of an inverted chain 5 connected to the support frame 1, an index weight gauge 6 connected with the inverted chain 5, and a pressure test joint 7 connected with the index weight instrument 6. The pressure test joint 7 is connected to the packing device 2 is connected.

[0029] The packer 2 is connected with the pressure test joint 7 through the pressure cap 10 .

[0030] The chain link 5 is a 10t chain link.

[0031] A circulating pump 8 is also arranged between the heating pool 4 and the simulated oil well 3 .

[0032] A thermometer 9 is install...

Abstract

The invention discloses a simulation test device used for a packer. The simulation test device used for the packer is mainly composed of a support frame (1), a suspension device arranged on the support frame (1) and the packer (2) connected with the suspension device. The packer (2) is arranged in a simulation oil well (3). The simulation test device used for the packer further comprises a heating bath (4) connected with the interior of the simulation oil well (3). The invention further discloses a packing-removing tension test method based on the simulation test device. Through simulation of the working state of the packer in the well, the packing-removing tension of the packer is tested, and the ex-factory usage quality of the packer is ensured.

Description

technical field [0001] The invention relates to a simulation test device for a packer and a method for testing its unsealing tension. Background technique [0002] In crude oil production at home and abroad, mechanical oil recovery occupies the primary position, and in mechanical oil recovery, oil well pumps are the main ones. Oil well pump is one of the most basic, reliable and widely used oil pumping tools. According to statistics, the oil pump accounts for more than 90% of the mechanical oil production wells. The oil pump equipment plays a vital role in the entire crude oil production. The economic loss caused by the failure of the oil pumping device, especially the downhole device is extremely huge. Therefore, timely and accurate monitoring and judgment of the working status of the oil pump, and effective and timely processing of the failures that occur will not only greatly reduce the production cost of crude oil and obtain higher economic benefits, but will also help...
