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.
