辽河油田茨9区水平井开发方案预测

The Development Program Prediction of Horizontal Well in Liaohe Oilfield Ci 9 Block

茨9区油藏为发育边水的中孔中高渗油藏,利用直井开发的弊端日益凸现,水平井开发可行性研究的论证认为,该区油藏部署水平井开发优势明显。在剩余油分布规律的基础上利用数值模拟的方法对茨9区进行水平井开发方案设计,确定了水平井开发的目的层位、水平井段方向以及长度,并利用数值模拟对开发方案进行结果预测,结果表明水平井开发从累积产油量以及含水上升情况等方面都远优于直井开发,综上为茨9区的进一步开发提出新的方向。

Reservoir of Ci 9 Block is a reservoir of secondary porosity and high permeability with edge water, the disadvantages of vertical well development appear more and more.Feasibility demonstrations of horizontal well development come to a conclusion that advantage is obvious of horizontal well development in this block.On the basis of remaining oil distribution regularity,development programs of horizontal well has been done by using the method of numerical simulation. The key targe layers,direction and length of horizontal section were identified and predicted the results.It turned out that horizontal well development is far better than vertical well development from the cumulative oil production and water cut rising. These provide a new direction for further development Ci 9 Block.
