Abstract
Abstract This paper conducts analysis on problems occurred during the development of Sazhong Area in Daqing Oilfield such as small reserve controlled by basic well pattern, low ultimate recovery efficiency, etc. It introduces the solution of infilling adjustment, analyzes and evaluates on full scale various production indexes like production rate, formation pressure, control degree and production situation of different formations, effect in old wells, and ultimate recovery efficiency, etc. after each infilling adjustment. Result shows that recovery efficiency can be improved by 6–8% after primary infilling adjustment, 4–5% to 45.5% after secondary infilling adjustment, and to 47.48% after tertiary infilling adjustment. It was realized that only when certain well pattern density was reached through reasonable division of formation series and multiple infilling adjustment, can we improve the control degree of various kind of formations and the ultimate recovery efficiency, and develop the continental heterogeneous reservoir with high efficiency and high quality.
