Embodiment 1

[0023] Such as figure 1 As shown, the present invention provides a packer performance testing device, which includes a casing 14, the bottom end of which is fixed on the base 12 through a blind plug 11, and a tubing 17 is suspended inside the casing 14 through a tubing hanger 3, The lower end of the tubing 17 is connected with a packer 15 coaxial with the tubing 17, the bottom end of the packer 15 is connected with a ball seat 13, the upper end of the casing 14 is provided with a wellhead cross 4, and the first wellhead cross 4 is set. The first through pipe 1 and the second through pipe 2 are respectively perpendicular to the central axis of the casing 14, and the first through pipe 1 is provided with a first cement truck interface gate valve 18 for connecting the cement truck, and the second through pipe 2 is provided with a On the second cement truck interface gate valve 5 connected to the cement truck, a first high-pressure pipeline 20 and a second high-pressure pipeline 2...

Embodiment 2

[0037]On the basis of Embodiment 1, in order to increase the flow and velocity of the high-pressure liquid passing through the third high-pressure pipeline 22 and the fourth high-pressure pipeline 23 , the third high-pressure pipeline 22 and the fourth high-pressure pipeline 23 are communicated.

Embodiment 3

[0039] On the basis of Embodiment 1, in order to facilitate the observation of the leakage situation, especially the leakage situation when the pressure is tested, the lower observation port 10 is located on the pipe wall of the casing 14 between the ball seat 13 and the blind plug 11 .

Abstract

The invention provides a packer performance detection device. Through operating a high pressure needle type valve, a backwashing exit brake valve and a cementing truck interface brake valve on the packer performance detection device, conventional tests of seat sealing, voltage withstanding, decompression and the like of a detected packer are realized. And the tests can be extended to tests of other hydraulic tools, such as a bridge plug, a hydraulic anchor and the like. The device is especially suitable for debugging of the packer and other hydraulic tools, wherein the debugging is performed by a petroleum tool design and manufacturing company. A blind plug, a casing pipe, an upper viewing port, a lower viewing port, a first high pressure type needle valve, a second high pressure type needle valve, a third high pressure type needle valve and a well-head large cross are designed in an integration state so that an integration level of the packer performance detection device is high. After assembling and formation, the device can be used in an overall demolition state. And follow-up maintenance is convenient. Besides, parts used in the device are oil-field commonly-used standard parts so that material selecting, assembling and maintenance are easy. Mechanical processing work of the whole device is less and a service life of the packer performance detection device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of oilfield development, and in particular relates to a packer performance detection device. Background technique [0002] With the deepening of oilfield development, the oilfield water injection process is gradually improved, and the matching layering tools and control tools are also developing continuously. However, the current conventional detection methods are not very mature, and each design and production unit only relies on its own Through simple testing of products based on experience, the following defects generally exist: [0003] 1. The test device is simple and can only perform some functional tests; [0004] 2. The testing method is unscientific, and it is impossible to conduct a comprehensive and systematic test; [0005] 3. The procedure is cumbersome and the operability is not strong when conducting a comprehensive test; [0006] 4. The experimental working conditions are far from the actu...
