The present application discloses a detection method and equipment for clogging of oil well pipelines, which are used to solve the technical problem that the existing clogging detection methods of oil well pipelines are relatively simple and cannot be accurately judged. Among them, the oil well pipeline includes the pipe wall and the oil inlet; according to the preset time interval, the oil flow rate of each oil inlet corresponding to the current time interval and the pressure wave reflection signal of each pipeline section of the oil well pipeline are respectively obtained; The difference between the oil flow at the oil port and the standard flow, and according to the difference, determine the operating status of each oil inlet; and according to the pressure wave reflection signal of each pipeline section, generate the corresponding pressure wave change curve to According to the pressure wave change curve, determine the operating status of each pipeline section; determine whether the oil well pipeline is clogged according to the operating status of each oil inlet and each pipeline section, and determine the pressure wave reflection time according to the pressure wave change curve The location of blockage and the corresponding blockage amount of each pipeline segment.
Description
technical field [0001] The present application relates to the technical field of petroleum, gas and coking industries, in particular to a detection method and equipment for clogging of oil well pipelines. Background technique [0002] With the deepening of the development and utilization of oil and gas resources by human beings, the transportation of oil through long-distance oil well pipelines has become an indispensable transportation method in the mining process. With the long-term operation of the pipeline, solids such as paraffin and impurities are easy to accumulate and cause blockage of the oil well pipeline, which affects the normal working state of the pipeline. If the blockage is not dealt with in time, it will also cause pipeline leakage or burst, which is likely to cause safety hazards. It also causes a waste of resources. However, the existing oil well pipeline clogging detection method is relatively simple, and it is impossible to accurately judge the clogging...
