Research on optimization of single well testing workload and efficiency

摘要

With the enlargement of production scale and the increase of survey and adjustment work, the mismatch between test requirement and test capability becomes more and more serious. In order to further control the test cost and improve the efficiency of survey and adjustment, according to the characteristics of the peripheral oil reservoirs and sections, differential management of survey and adjustment cycle and effective methods of matching injection points are actively carried out, on the basis of satisfying the development requirements and smooth operation of various indexes, solve the mismatch between test requirements and test capabilities. By analyzing the use cycle of test data under different conditions, the type of wells with extended use cycle is determined, which can effectively reduce the need of test work under the condition that the separate layer water injection is qualified. The distribution rules of different sizes of nozzles are statistically analyzed, and the selection rules of nozzles in special layers are made clear in advance to improve the debugging efficiency of injection allocation point.
