Embodiment 1
[0051] This embodiment provides a temperature and pressure profile tester, the temperature and pressure profile tester includes: a temperature sensor, a thin-walled packaging tube, a pressure conduction capillary, an anti-blocking pressure guiding structure, a pressure sensor, a data acquisition chip, a heat insulation cavity and a sealing connecting barrel;
[0052] The temperature sensor is packaged in a thin-wall package tube for measuring the downhole temperature;
[0053] One end of the sealed connection cylinder is connected to the thin-walled packaging tube, and the other end is connected to the heat insulation chamber;
[0054] The pressure sensor is installed in the heat insulation cavity, connected to one end of the pressure conduction capillary, and used to measure the pressure transmitted by the pressure conduction capillary;
[0055] The data acquisition chip is installed in the heat-insulating cavity, connected to the pressure sensor and the temperature sensor r...
Embodiment 2
[0074] This embodiment provides a specific temperature and pressure profile tester, such as figure 1 As shown, the tester includes: a protective cover 101, a thin-walled packaging tube 102, a temperature sensor 103, an anti-blocking pressure guiding structure 104, a sealed connection cylinder 105, a pressure chamber 106, a heat insulation chamber 107, a pressure conduction capillary 108, a pressure Sensor 109, data acquisition chip 110, wireless transmission chip 111, output port 112, battery cartridge 113, magnetic locator 114, heat absorber 115; wherein,
[0075] The protective cover 101 is a metal cover-like structure with openings on its surface, and a thin-walled packaging tube 102 and an anti-blocking pressure-guiding structure 104 are installed inside to protect the thin-walled packaging tube 102 and the anti-blocking pressure-guiding structure 104 , to avoid being damaged in the downhole environment, and at the same time, the thin-walled packaging tube 102 and the anti...
Embodiment 3
[0098] This embodiment provides a temperature and pressure profile testing device, which includes: the temperature and pressure profile tester provided in Embodiment 1 and a shock-absorbing protective support;
[0099] The shock-absorbing protection support cylinder includes a screen pipe, shock-absorbing joints at both ends, a connecting head and a guide cone; wherein,
[0100] The screen pipe is an oil pipe with a plurality of round holes evenly distributed on the pipe wall;
[0101] The damping joints at both ends are respectively connected to the two ends of the screen pipe, and the damping joints at the ends specifically include:
[0102] The main body of the first shock-absorbing joint is connected with the end of the screen pipe with a thread, and a first partition is provided in the middle, and a first perforation is provided in the center of the first partition;
[0103] Two first damping springs are respectively arranged on both sides of the first through hole;
