Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the drawings.
[0015] An autoclave mold for testing self-expanding packers, see figure 1 As shown, it is composed of a self-expanding packer and an autoclave. The self-expanding packer is composed of a test piece base pipe 11 and a self-expanding rubber 12; the autoclave is composed of oil pipe 1, fixed ring 3, left end cylinder 4, right end cylinder 14, The packer test piece 5 and the disposable sleeve 6 are composed; the left end cylinder 4 and the right end cylinder 14 are composed of the tubing port 2, the wide gasket 7, the car’s seal ring 8, the casing gasket 9, and the sealing taper thread 10. , And the cylindrical sealed structure formed by the base tube 11 of the test piece.
[0016] The disposable sleeve 6 is connected with the left end cylinder 4 and the right end cylinder 14 through the sealing taper thread 10; during the test, the self-expanding rubber 12 on the packer test piec...

The invention discloses a seal-type autoclave for testing a self-expansion packer, and the autoclave comprises an oil pipe (1), an oil pipe port (2), a fixed ring (3), a left-end cylinder (4), a packer testing part (5), a disposable sleeve (6), a wide spacer (7), a Che's sealing ring (8), a casing pipe spacer (9), a sealing conical thread (10), a testing part base pipe (11), self-expansion rubber (12), a groove (13), and a right-end cylinder (14). The autoclave achieves the good sealing of hydraulic oil, and is not liable to cause corrosion. The autoclave can meet the requirements for different pressure tests. The autoclave is convenient to disassemble and assemble, and is simple in operation. The autoclave is easy to machine and transport, and can be used under high temperature and pressure.
Description
Technical field [0001] The invention relates to the field of packer test devices for drilling operations, in particular to an autoclave mold that puts a self-expanding packer into it and pressurizes inward through both ends to realize the performance detection of the self-expanding packer . Background technique [0002] It has been a worldwide problem to solve the problem of oil, gas, and water channeling between the casing and the cement ring after cementing, and the micro-ring gap between the casing and the cement ring after the cement has solidified. Packers that expand in contact with oil, gas or water have been developed at home and abroad and have been successfully applied to the field. The basic principle is that the tool is run into the well along with the casing, and it can expand automatically when it encounters oil, gas or water. Based on the superior performance of the swelling packer in contact with oil, gas or water, it can solve the problem of oil and gas channeli...
