中文摘要:
      苏北盆地常规油气资源较为匮乏,非常规领域勘探程度低,综合地震、岩电、试油等资料,利用物化分析、井震多维解释等手段,从烃源岩和储层特征入手,认识到ZJ探区阜宁组二亚段和泰州组二亚段广泛发育2套源储一体式的页岩油藏,油藏整装且资源量丰富;探索形成了一套地质工程一体化评价技术体系,从源岩品质、储层品质和工程品质综合评价页岩油藏特征,创新利用“岩、电、震”手段综合识别辉绿岩,精准刻画其空间展布特征,划分3种油藏类型,全过程指导钻井压裂试油,并通过老井复查,实现了页岩油藏纵横向上的全方位突破,4口井/7层获高产油流,初步圈定有利面积70 km2,资源量超亿t,对浙江油田乃至整个大南方非常规资源勘探具有重大意义。
英文摘要:
      Subei basin is short of Conventional oil and gas resources, whereas in terms of unconventional resources, the exploration is still in a low level. Based on the data of seismic, rock-electro and well testing, this article, using the means of physical chemical analysis and well seismic multidimensional interpretation,found out that there are abundant and monolithic shale oil resources in source rock in the 2nd member of Funing Formation and the 2nd member of Taizhou Formation in North Jiangsu exploration area. an evaluation system of geology-engineering integration was formed to comprehensively evaluate the quality of the source rock, the reservoir and the engineering using the “rock-electro-seismic”method to recognize diabase and its spatial distribution. Three types of reservoirs are classified. 4 wells /7 layers achieve high oil flow. The favorable area is about 70 km2 and the amount of resources is over billion tons. It is of great significance for the exploration of unconventional resources in Zhejiang oil field and the whole southern area of China.
