Description

Auxiliary tool for testing work diagram of oil pumping unit of coal-bed gas well Technical Field The utility model belongs to the technical field of coal-bed gas well pumping unit work diagram testing, and particularly relates to an auxiliary tool for testing the coal-bed gas well pumping unit work diagram. Background The coal bed gas is taken as a clean energy source, increasingly important positions are occupied in energy structures in China, normal operation of the coal bed gas well pumping unit plays a key role in coal bed gas exploitation efficiency and quality, the work pattern test is an important means for evaluating the working state of the pumping unit, diagnosing underground faults and optimizing production parameters, the change condition of load and displacement of the pumping unit in the operation process can be intuitively known through the work pattern test, further, the working condition of the pumping unit, the elastic deformation of an oil pipe, the position of a liquid level and whether faults such as sand clamps and gas locks exist or not are judged, an accurate work pattern test result can provide scientific basis for production management of the coal bed gas well, timely adjustment of the production parameters is facilitated, targeted treatment measures are timely made on underground abnormal conditions, and the pump detection period can be effectively prolonged. At present, in the work of testing the work of the pumping unit of the coal-bed gas well, two workers are generally used for matching operation, the specific operation flow is as follows, firstly, two workers are required to finish the installation of the work tester by stopping and adjusting the position of the square clamp for two times in sequence, after the installation is finished, the pumping unit is started again, the pumping unit is enabled to run for a certain time, so that the testing equipment can acquire enough data, secondly, the two workers are required to finish the disassembly of the work tester by stopping and adjusting the position of the square clamp for two times in sequence, the testing equipment is taken down, the testing data is read and recorded, and in order to obtain comprehensive work information, the operation is required to be carried out for a plurality of times, at least four times of stopping are required, the traditional testing method has a plurality of defects, firstly, the operation is required to be carried out strictly according to operation rules, a plurality of steps and links are involved, such as power supply closing, equipment state checking, control parameter adjusting and the like, the two links are required to be closely matched, the faults can possibly cause testing failure, equipment or personnel damage, and the operation is complicated, the time is longer, the probability of the occurrence of the failure of the pump blocking under the well is greatly increased. Disclosure of utility model The utility model aims to provide an auxiliary tool for testing the work diagram of a coal-bed gas well pumping unit, so as to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: an auxiliary tool for testing a work diagram of a pumping unit of a coal-bed gas well, comprising: The gas production tree is internally provided with a polished rod, the polished rod reciprocates up and down in the gas production tree, a rope hanger is movably sleeved on one side of the polished rod, a first square clamp and a second square clamp are mounted on one side of the polished rod, which is close to the rope hanger, through bolts, and a third square clamp is mounted on the top of the polished rod, which is close to the top of the gas production tree, through bolts; The auxiliary device is arranged on the polish rod between the square three clamp and the gas production tree, the auxiliary device comprises a main body, the cross section of the main body is of a U-shaped structure, a lock hole is formed in the inner side of the main body, a cylinder body is fixedly arranged in the lock hole, a limit ball is inserted into the cylinder body, and a spring is connected between the cylinder body and the limit ball.
