义901块位于渤南油田义99井区南部,义141块北部,为一断层遮挡的断鼻构造,南北均被断层遮挡。通过该块的精细构造解释,并且与南北已钻老井资料的对比分析,加大沉积规律研究力度,利用相控储层描述技术,滚动开发义901块。 Yi 901 block is located in the southern part of Yi-99 well block in Bonan Oilfield and is located in the north of Yi-141 block. It is a fault-broken nose-break structure and is blocked by faults. Through the detailed structure interpretation of the block, and with the comparison of the data of the old drilling wells in South and North China, the research on depositional rules is intensified. By means of phased reservoir description technology, the 901 blocks are rolled and developed.
