Detailed Description
The present invention will be described in detail with reference to the drawings and examples, and the scope of the present invention is not limited to the following.
As shown in fig. 1, the invention provides an oil and gas well explosion perforating string mechanical experiment device, which comprises a high-temperature and high-pressure generator 1, a high-temperature and high-pressure container 2, a perforating string 3, a cable 4, a signal amplifier 5, an a/D converter 6 and a computer 7. The high temperature and high pressure generator 1 is connected to the high temperature and high pressure vessel 2 via a pipe, and a safety valve and a pressure relief device (not shown) are provided on the pipe between the high temperature and high pressure generator 1 and the high temperature and high pressure vessel 2. The high-temperature and high-pressure container 2 is internally provided with a pressure sensor and a temperature sensor (not shown in the figure) to form a real simulation of the whole well bottom environment. A perforating string 3 is disposed within the high temperature, high pressure vessel 2, and the perforating string 3 is connected to a cable 4. The cable 4 transmits the perforating string 3 measurement signal to the signal amplifier 5, while the perforating gun is detonated by the cable 4 at the time of the experiment. The a/D converter 6 converts the analog signal transmitted from the signal amplifier 5 into a digital signal, and inputs the digital signal to the computer 7. In the computer 7, the vibration and stress conditions of the whole pipe column during explosion are obtained by processing the acquired signals.
In a preferred embodiment, perforating strings 3 are combined according to the subject, as shown in fig. 2, which is a part of a perforating string for a casing perforation completion. Perforating string 3 comprises perforating gun 301, acceleration test nipple a302, shock absorber 303, acceleration test nipple B304, packer 305, tubing 306, and outer casing 307; perforating gun 301, acceleration test nipple a302, shock absorber 303, acceleration test nipple B304, packer 305, and tubing 306 are all located inside outer casing 307. The top of the perforating gun 301 is provided with an acceleration test nipple A302, a shock absorber 303, an acceleration test nipple B304 and an oil pipe 306 in sequence, and a packer 305 is arranged between the oil pipe 306 and an external casing 307. The sensor can be conveniently arranged by adopting the two acceleration test pup joints, and the wiring is simple. When the oil pipe 306 is used for carrying perforation and formation test combined operation, a pressure gauge, a clock and other downhole instruments need to be connected to the perforation string 3 through investigation.

The impact acceleration sensor has the characteristics of high rigidity, quick response and large g value, and is widely applied to explosion test and other occasions.
In the above embodiment, the impact acceleration sensor a402 coincides with the rotation axis of the acceleration test nipple a302 for testing the axial acceleration (longitudinal vibration); the impact acceleration sensor B403 is arranged in the radial direction for testing the radial acceleration; the impact acceleration sensor C405 is arranged perpendicular to the impact acceleration sensor B403 in a tangential direction for testing the circumferential acceleration. Three cables a404 for connecting the three impact acceleration sensors are bound together in a bundle to be used as the cable 4.
In a preferred embodiment, as shown in fig. 4, a pressure sensor a406 and a pressure sensor B407 are provided on the outer sleeve 307. Both pressure sensors are screwed onto the casing wall of the outer casing 307 (and screwed with a locking glue) and the sensitive elements of the pressure sensors face the inside of the outer casing 307 for measuring the pressure inside the casing 307. Pressure sensor A406 is located on the side near perforating gun 301, below packer 305; pressure sensor B407 is located above packer 305. When the perforating gun 301 is detonated, the instantaneous pressure across the packer 305 can be measured, and the impact of the detonating packer's sealing performance can be analyzed.
