马厂油田已进入开发后期,综合含水率高达92 %。为实现油田的增储稳产,缓解老区产量压力,2001 年对马厂油田北部复杂带进行了以滚动增储为目标的综合地质研究。该项研究以地层精细对比和三维地震多参数解释为技术核心,通过地质、物探、测井、钻井、试油资料的有机结合,搞清了马厂北部构造格局,落实了6 个有利的含油气目标区,部署滚动开发井4 口,探明石油地质储量800 kt ,天然气地质储量117 km³ ,实现了复杂断块油田的滚动增储。

The fields of Machang are located on south of central arch of Dongpu depression. These fields are composed of little fault block reservoirs. Now the moisture content of these fields have reached 92 percent. In order to increasing reserve and keeping production , in 2001 , the fields in morth Machang were been researched . As the key careful contrasting formation ,full 3D processing and tdchnology and multi - parameter inversion of seismic technology been applicated in this research .By using the references of drilling 、loging and testing , the reservoirs were been deep understanded step by step. The geat achievment such as mew oil blocks、increasing reserve have been gotten in north of Machang fields.
