ABSTRACT: In view of the rapid decline rate of oil production and gradual increase of
water cut in oil wells in Block S, based on the determination of the formula of
foam profile control agent, the optimization study of foam profile control injection
scheme was carried out. Petrel software is used to establish a facies controlled
geological model based on stochastic modeling method in Block S, and CMG software
is used for numerical simulation to design 7 sets of foam profile control prediction
schemes. Dynamic data and numerical simulation methods are used to optimize foam
injection mode and injection cycle. By simulating and calculating, the optimal injection
method of alternating gas and liquid injection and the optimal plan with an injection
period of 2 months were selected. Through the calculation results of various research
plans, it can be seen that the water content of the optimal plan has decreased significantly,
and the oil production rate has increased significantly, in order to slow down production
decline, control water content rise, extend the economic recovery period of the
oilfield, and achieve the goal of improving oil recovery.
