摘　　要：致密油在周长油区X部分布广泛,地质储量丰富,但因地面条件复杂,注水开发未上规模,开采方式效果较差,储量动用程度低,部分油井处于停抽或未投产状态。因此,文章分析了周长X部致密油层的勘探开发特征,提出了开发部署与方案设计,并针对性地对开发指标进行预测,得出了该研究区要用直井+水平井联合开发井网的方式开采方可提高采收率的结论。Tight oil is widely distributed in part X of the Zhouchang oil area,with rich geological reserves.However,due to the complex surface conditions,the water injection development is not on scale,the effect of the production method is poor,and the degree of reserves utilization is low.Some oil wells are in the state of stopping pumping or not being put into production.Therefore,this paper analyzes the exploration and development characteristics of tight oil reservoirs in part X of Zhouchang,puts forward the development deployment and plan design,and makes targeted prediction of the development indicators,and draws the conclusion that the study area can improve the oil recovery only by using the combination of vertical and horizontal wells to develop the well pattern.
