断面构造图的绘制及在油田调整挖潜中的应用

Drafting of Fault Plane Structural Diagram and Its Application in Fault-Block Oilfield

为解决复杂断块油田调整挖潜中因断层空间展布认识不清导致新钻调整井达不到设计目的的问题 ,借助于现有的钻井、测井、三维地震等大量的动、静态资料 ,在区域构造和断层分布规律等研究基础上编绘出主控油断面构造图。依据端面构造图对其所封挡的油藏构造和剩余油分布精细描述 ,应用定向井技术沿断层面设计双靶定向井 ,挖掘油藏潜力。设计的开发井均达到了预期目的 ,投产效果良好 ,取得了明显的经济效益。端面构造图直观地反映出断层空间分布特征。通过断面构造图的应用 ,较好地解决了复杂断块油田调整挖潜中的一些难题 ,在油藏开发中发挥了重要作用。

In order to introduce a method to solve some problems in the process of adjustment well drilling in complex fault-block reservoir, On the base of regional structure and the rule of fault distribution, a lot of dynamic and static data obtianed by drilling, logging and 3D seismic data are used to draft the surface structure of main controlling faults. Based on the drawings, the precise description of reservoir structure and remaining oil distribution were made. By means of directional well technique, the twin targets dirctional wells have played special roles in it, the adjustment wells are succeed, the effect is remarkable and the economic benefit is obvious. The drawings have solved some problems in the tap production potential and its application has made important action at the middle-late period of the complex Fault-Block Oilfield.
