Embodiment Construction
[0026] Such as figure 1 As shown, the test system of this scheme is composed of three parts: downhole equipment, cable 5 and ground equipment. Analyze various data to draw conclusions about the underground situation.
[0027] The downhole equipment includes: support tube 1, positioning joint 2, direct reading pressure gauge 7, receiver 12, battery 6, storage electronic pressure gauge 9, etc. Multiple grooves 15 are opened on the outer wall of the support tube depending on the situation. There are four grooves 15 on the outer wall of the cylinder 1, in which the direct-reading pressure gauge 7, the battery 8, and optionally one or two storage pressure gauges 9 are installed, and a pressure transmission channel is opened in the tube wall of the cylinder 1 13 Transmit the pressure under the test valve test valve 4 to the direct-reading pressure gauge 7 or / and storage pressure gauge 9, inside the direct-reading pressure gauge 7 are installed sensors, A / D modules, microcontrollers...
