示踪剂井间监测技术在马厂小断决油田的应用

Tracer Observating Technology and Its Application in the Small Fault-Block Reservoir, Machang Oilfield

马厂油田是一个地质条件较为复杂的小断块油田，开采难度大。开发以来，对一些断层的密封性、井问的连通性以及纵向上的非均质性还不甚清楚，给有效注水和工艺措施带来一定困难。应用放射性同位素示踪剂井间监测技术较好地解决了这些问题。检查了断层的封闭状况；验证了油水井的连通状况；计算出注水井在平面上各个方向的渗流速度；了解了油井的水淹方向；确定了油井纵向上的非均质性；落实了马10块和马11块的构造格局。为马厂油田的油水井调整、工艺技术措施和综合治理提供了可靠的科学依据。

It is difficult to develop the small fault-block reservoir for its complicated geologic conditions in Machang Oilfield. In the past few years,there were some difficulties in water injection and technical measures,because some fault sealing characteristics and interwell communication as well as longigudinal heterogeneity had not been known clearly. At present,the tracer observating technology has been used to solve many problems as follows:the fault sealing features,communication between wells,percolation flow velocity in various plane directions, waterflooded directions,vertical heterogenity as well as the tectonic frameworks of Block Ma 1O and Ma 11. It offers a reliable scientific method for the adjustments,technical measures in Machang Oilfield.
