Layered testing and adjustment process for injection well

A layered testing and adjustment process for an injection well mainly solves the problems that an existing testing and adjustment process is carried out separately under a well shutin circumstance, the number of devices and tools is large, and long time is consumed. The specific testing and adjustment process includes the following steps that firstly, according to an existing throwing and fishing method, blanking plugs in eccentric water distributors in various layers are fished out and then blockage type flowmeters are thrown into the eccentric water distributors in the layers; secondly, different types of injection pressure are adjusted at the mouth of the well, the injection allocation flow of the whole well is 0-150%, and three to six points are selected for pressure adjustment; thirdly, the blockage type flowmeters in the layers are fished out, and testing data are obtained; fourthly, packer seal examining is implemented; fifthly, layered flow adjustment is implemented; sixthly, layered well testing and pressure measurement are implemented. The layered testing and adjustment process for the injection well has the advantages that under a well non-shutin circumstance, layered pressure measurement is completed at the same time, the number of devices and tools is small, operators have no special skill requirements or testing and adjustment experience, and data can be synchronized.
