Abstract
Because the Mabei1 oilfield is bottom water reservoir,water flooding development effect is poor.In order to improve the recovery rate,gas injection experiment which uses the concept of top gas injection flooding technology of gravity is carried out in two well groups in the oilfield.It has great guiding significance for the next step to optimize the perforation production plan to grasp the movement of gas-liquid interface in time.PNN monitoring formation of gas and liquid interface has a strong advantage in the casing well,e.g.,it mainly uese long spacing & short spacing overlapp,so there has a more obvious deviation in gas layer.26 times PNN time lapse loggings have been made in the Mabei1 oilfield to konw the experiment well's gas-liquid interface migration and the direction,which provides a scientific basis for the next step to optimize the production program.关键词
