Abstract
Taking Chang 4&5 reservoir in Q area of Ordos Basin as the research object, through comprehensive analysis of laboratory sensitivity test, scanning electron microscopy, physical property test and X-ray diffraction, the Chang 4&5 reservoir in the research area has the characteristics of weak velocity sensitivity, weak water sensitivity, weak salt sensitivity, moderate partial weak acid sensitivity and weak alkali sensitivity and so on.The three characteristic critical values are:the critical flow rate is 0.75ml/min, the critical salinity is about 8000mg/L, and the critical pH is about 8.5关键词
