EMULSIFICATION LAWS OF THE PRODUCED LIQUID OF ASP FLOODING PILOT TEST IN DAQING OILFIELD
摘要
Abstract
In view of the emulsified phenomena of the produced liquids at different stages of ASP pilot test, the liquids at different ASP injected stages and in various produced modes are monitored and researched. The laboratory experimental results show that at the injected stage of ASP main slug, the principal factor in the produced liquid is water, the water cut is below 40% , is prone to form o/w emulsion; when the water cut reaches 40% - 65% , is easy to generate slight o/w or w/o emulsions; when the cut is up to 65% -80% , is likely to produce slight o/w e-mulsion; as the cut is more than 80% , it is not easy to be emulsified. At the stage of the auxiliarily injected slug, when the water cut is more than 85% , the o/w emulsion is easily formed. For the binary alternating injection mode, the emulsified degree of the o/w emulsion is much more higher than that of conventional ASP system. The studies on the emulsified laws of the produced fluid can provide the evidences for the monitoring and adjustment of the pilot test and moreover the further enhanced oil recovery.关键词
