核磁共振测井资料在桩1区块底水油藏开发中的应用

针对桩1区块特高含水期底水稠油油藏的开发特点,利用核磁共振测井资料,定量评价其孔隙流体流动特性,准确划分产层,直接识别油、气、水层,准确地评价了区块剩余油分布情况。并依此部署了水平井,取得了很好的开发效果。实践证明,核磁共振测井具备常规测井所不具备的某些技术优势,能解决一些特殊的地质问题,有广阔的应用前景。

The application of nuclear resonance log for the bottom water reservoir development in Zhuang1 block

According to the development behavior of the heavy oil reservoir with base water in Zhuang1 block, during thehigher water-cut phase, we quantitatively evaluated the flow behavior of pore fluids, calibrated exactly the productivelayers, distinguished directly the oil, gas, acquifer layer, so as to evaluated exactly the distribution of the residual oilin the area by using the nuclear magnetic resonance log data. Good development results were obtained after some hor-izontal wells were drilled according to the research. The facts have proved that the nuclear magnetic resonance loghas some technical advantages over those the conventional logs with which some special geologic problems can besolved with it. It has wide application prospect.
