苏北盆地溱潼凹陷草舍油田构造及油气分布特征

STRUCTURES AND PETROLEUM DISTRIBUTION IN THE CAOSHE OILFIELD OF QINTONG DEPRESSION IN THE SUBEI BASIN

草舍油田自 2 0世纪 70年代初开始钻探工作 ,迄今已打 40多口井 ,先后在三垛组一段、戴南组二段和一段、阜宁组三段和一段及泰州组 6个层位获得工业油流。随着勘探程度的不断深入 ,逐步完善了该区的开发井网 ,并对该区的构造特征、油气分布规律、控油因素。

Drilling began in the Caoshe Oilfield in the early of 1970s.And up to now,more than 40 wells have been drilled.Industrial oil flows have been hit in the first member of Sanduo Formation,the second and first members of Dainan Formation,the third and first members of Funing Formations and also in the Taizhou Formation.With the going-on of the drilling,the well net for oil development in the area has been improved,and better understanding of the structural characteristics,petroleum distribution,oil-controlling factors,and development prospect has been acquired.
