Abstract: Since in some small fault block of Jinzhou oil field,the oil bearing area is small,the reserves scale is small,the majority of oil deposits are adopted the natural energy development, but the development effect is bad.In recent years, through optimized screening,we strengthened the geological comprehensive study,carried out the structure and the distribution relations of oil and water,considered to takes suitable measures for the study block,and adopted different development technology in view of the different type of oil deposit, which has enhanced oil-producing rate,increased the recoverable resources.
