摘要:
海上L区目标层属于海上特低渗储层,为准确进行储层分类评价、指导储层有利区的优选,在统计借鉴已有低渗储层分类评价成果基础上,结合目标区低渗储层特征,厘定低渗储层分类评价参数,采用综合分类系数法完成低渗储层分类评价及有利区优选。研究认为L区目标层主要发育Ⅲ类储层,其次是Ⅳ和Ⅴ类储层,Ⅰ、Ⅱ类储层不发育,Ⅲ类储层连片分布的区域为储层有利区。研究结果可以较好地指导储层开发有利区的优选。
Abstract:
The target layer of the offshore L area belongs to the offshore ultra-low permeability reservoir. To accurately classify and evaluate the reservoirs and guide the selection of favorable reservoir areas,based on the statistical reference of the existing classification and evaluation results of low-permeability reservoirs,combined with the characteristics of low-permeability reservoirs in the target area,the classification and evaluation parameters of low-permeability reservoirs were determined,and the comprehensive classification coefficient method was adopted to complete the classification and evaluation of low-permeability reservoirs and the selection of favorable areas. The results show that Class III reservoirs are mainly developed in the target layer of L area,followed by Class IV and V reservoirs,Class I and II reservoirs are not developed,and the contiguous distribution area of Class III reservoirs is a favorable area for reservoir development. The research results can better guide the selecting favorable areas for reservoir development.
