Study Of Synthesizing Application Test And Modification New Technique To Enhance Quality Of Separate Flood In Oilfield

The quality of seParate flood is related to modification effect of oilfield develoPment. The La Madian oilfield has come to the stage of contain extra high water. The quality of samPling isolated test data must ensure the effect of seParate flood, all tyPes of tests, synthesis modification and fine Program. In this PaPer, sealing effect of excluders, seParate effect of well of injection Polymer and constant flow decenter water distribution technique are studied by document retrieval, theoretical analysis and Practice exPerience. On the basis of it, the judgment method of excluders seal is Provided to imProve the accuracy and affectivity of data of well of injection water. These can helP check the effect of job execution in well of injection water, mode of oPeration of excluders, casing Protection and quality of seParate flood. Allocation method and oPerating rules and regulations are constructed to suit seParate injection technique of Polymer flooding. The requirement of seParate flood of Polymer flooding is satisfied. Effect of Polymer exPloration is enhanced. Ultrasonic flow meter is aPPlied to imProving efficiency of test modification and data rePeatability. The data is Provided by dynamic analysis of water flooding. By studying the aPPlicability of constant flow decenter water distribution technique, not to increase test workers and vehicle, the factors of interval ProPerty and water nozzle are considered. Cycle of test is shortened and work efficiency is enhanced.
