针对义97块储层物性和连通性差、储量动用程度低、长期处于停产状态的突出问题,运用精细油藏描述方法,在沉积相、储层、微构造及剩余油分布规律重新认识的基础上,进行滚动扩边、井网井距优化,制订以水驱为主的开发调整方案。现场实施取得良好的效果,使义97块储量得到二次开发动用,为提高采收率奠定基础。该研究对同类型油田的二次开发调整有一定的指导和借鉴意义。
In view of the prominent problems of Yixian 97 reservoir, such as poor physical property and connectivity, low utilization of reserves and long-term shutdown, based on the understanding of sedimentary facies, reservoirs, micro-structure and the distribution of remaining oil, using the fine reservoir description method , Rolling edge expansion, well spacing optimization, development of water-driven development and adjustment programs. The implementation of the site achieved good results, so that 97 reserves were redeployed and utilized, laying a foundation for enhanced oil recovery. The research has some guidance and reference significance for the secondary development and adjustment of the same type of oilfield.
