[0022] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0023] like Figure 1-6 As shown, a pump condition meter with four test passages includes a flange head 1, a keel 2, a tail buckle 3, a sleeve 4, a top screw 5, a straightening tube 6, an O-ring 7, a sensor A8, a sensor B9, a sensor C10, an electrical component 11, and a water content sensor 12.

[0024] The flange head 1, keel 2, and tail buckle 3 are connected in sequence. After the flange head 1, keel 2, and tail buckle 3 are assembled, they are placed in the sleeve 4. A top screw 5 is placed at the fixed position of the flange head 1 and the sleeve 4 to prevent the equipment from being buckled due to impact and vibration underground; in addition, an O-ring 7 is placed on the flange head 1 and the tail buckle 3 to ensure the sealing of the entire equipment.

[0025] The size of the flange on the flange head 1 of the present application is consistent with the size of the conventional motor tail buckle, which can realize the connection between the pump condition instrument and the unit.

[0026] Two pressure measuring pipelines are arranged in the flange head 1, namely the first pressure measuring pipeline 1-3 and the second pressure measuring pipeline 1-4. One end of the first pressure measuring pipeline 1-3 and the second pressure measuring pipeline 1-4 are both connected to the outside, the other end of the first pressure measuring pipeline 1-3 is connected to the sensor B9, and the other end of the second pressure measuring pipeline 1-4 is connected to the sensor A8.

[0027] The third pressure measuring pipeline 3-1 is set in the tail buckle 3, and the third pressure measuring pipeline 3-1 is L-shaped. One end of the third pressure measuring pipeline 3-1 is connected to the outside, and the other end is connected to the sensor C10. In the present application, two pressure measuring pipelines are set in the flange head 1 and one pressure measuring pipeline is set in the tail buckle 3. The three pressure measuring pipelines are connected to the downhole pressure pipeline, and three downhole pressure parameters can be measured simultaneously.

[0028] In addition, the flange head 1 is provided with a liquid transmission channel 1-1, one end of which is connected to the outside, and a longitudinal groove 1-2 is provided inside the channel, each groove having a width of 2 mm, and a water content sensor 12 is arranged at the other end of the liquid transmission channel 1-1, and a test probe 12-1 of the water content sensor 12 is a porous tubular structure. The siphon effect brought by the longitudinal groove 1-2 facilitates the introduction of external liquid into the water content sensor 12, and the test probe 12-1 of the water content sensor 12 is a porous tubular structure, which can increase the release area between the sensor and the liquid.

[0029] The water content sensor 12, sensor A8, sensor B9 and sensor C10 are connected to the electrical component 11 through a line, and the electrical component 11 is arranged on the keel 2. The water content sensor 12 of the present application can be a sensor with the same structure and function as the oil water content sensor JWB2 (Jiuwei Zhijian), and the size can be adaptively adjusted. Sensor A8, sensor B9 and sensor C10 can select suitable commercially available sensors according to different working conditions.

[0030] In the present application, a centralizing pipe 6 is welded on the outer wall of the sleeve 4, and the centralizing pipe 6 has a centralizing effect on the equipment. At the same time, there is no need to place a centralizer at the bottom to avoid affecting the connection of the pressure pipeline.

[0031] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in the field should fall within the protection scope of the present invention. The technical contents for which protection is sought in the present invention have been fully recorded in the technical requirements.
