摘要 马王庙地区新沟嘴组下段具有良好的油气成藏地质条件,其岩性特征、成岩作用及砂体物性、沉积微相等因素控制了该区新下段时期的有利储集区带分布。通过各个主控因素的数据统计分析,制定出该区各主控因素与储层发育关系的分类评价标准。叠合各主控因素评价结果,以油组为单位编制了各油组的有利储集区带分布预测图,有效地预测了该区新下段有利储集区带。研究表明马王庙地区新沟嘴组下段Ⅲ油组时期一类和二类储层发育区分布面积广,三类储层发育少。Ⅱ油组时期一类和二类储层分布更广,以东部分支为主,西北部也有发育,三类储层面积小。Ⅰ油组一类储层发育局限,仅分布于研究区东北角的岳参2井—板7井一带,而三类储层相对其它两个油组时期发育。 The lower section of Xingouzui formation in Mawangmiao region has good oil and gas accumulation geo logical conditions,and its lithology,diagenesis and sand body,sedimentary micro-facies and other factors control the distribution of favorable reservoir zones of lower section of Xingouzui formation in this area.Through statistical anal ysis of various controlling factors,we established the criteri on for classified evaluating the relationship between various controlling factors and reservoir development.Combined with the composite evaluation results,we compiled the dis tribution prediction maps of the favorable reservoir zones of each oil group with the oil group as a unit,and effectively predicted the favorable reservoir zones of lower section of Xingouzui formation in this area.Studies show that Class Ⅰ and Class Ⅱ reservoirs developed widely for lower oil group Ⅲ in Xingouzui Formation of Mawangmiao area during the reservoir development of oil group Ⅲ,but Class Ⅲ reser-voirs seldom developed;Class Ⅰ and Class Ⅱ reservoirs devel oped more widely mainly in the eastern part and minor in the western part during the reservoir development of oil group Ⅱ,while the developing area of Class Ⅲ reservoirs is small;Class Ⅰ reservoirs developed only in the area of Well Yuecan 2-Well Ban 7 in the northeast corner of the study area dur-ing the reservoir development of oil group Ⅰ,while Class Ⅲ reservoirs relatively developed compared with the reservoir development of other two oil groups.
