摘要
杨税务潜山带位于冀中坳陷廊固凹陷东部,是华北油田油气接替的新领域,由于潜山地层岩性复杂,储集层空间展布差异大,在油气层评价、储集层改造过程中出现了多层岩性与电性、显示与试油结果不对应或矛盾的现象。针对这一难题在该区采用XRD矿物分析技术对岩性精细定名,应用随钻镜下岩石薄片鉴定技术对杨税务潜山奥陶系的岩石微观特征进行储集空间分类评价。结果表明,上马家沟组下段、亮甲山组为该区最好的碳酸盐岩储集层;峰峰组下段、上马家沟组上段、下马家沟组下段为该区较好的碳酸盐岩储集层,明确了进一步勘探改造选层目标。
Yangshuiwu buried hill zone is located in the easy of Langgu Sag,Jizhong Depression,and is a new field for oil and gas resources in Huabei Oilfield.Due to the complex lithology of buried hill formation and great difference of reservoir space distribution,lithology and electricity,display and test results do not correspond or contradict during the evaluation of oil and gas and reservoir reconstruction.Therefore,XRD mineral analysis technology was applied to finely name the lithology in this area and microscopic identification of thin section while drilling was used to evaluate the reservoir space classification of microscopic characteristics of Ordovician rocks in Yangshuiwu buried hills.Results showed that the lower member of upper Majiagou Formation and Liangjiashan Formation are the best carbonate reservoirs in this area;Fengfeng Formation,the upper member of upper Majiagou Formation and the lower member of lower Majiagou Formation are better carbonate reservoirs in this area,which clarified the target of further exploration,reconstruction and layer selection.
