鄚州油田鄚31断块圈闭落实与评价
|
摘要
鄚州油田鄚31油藏为复杂断块中深层砂岩油藏,受构造、岩性双重控制,落实和评价断块圈闭是油藏开发的关键。通过GeoEast解释系统的多种几何类属性技术,精细解释小断层,利用高效层位追踪等技术落实断块圈闭;在此基础上,开展圈闭评价,优选纹理、高亮体等地震属性预测鄚31断块Es_3段储层分布规律,利用流体检测技术预测含油气性。研究结果表明,区内存在新的河道砂体和局部构造高点,据此在鄚31断块西南方向部署扩边井4口,其中3口井获高产油气流,取得了良好效果。该方法对同类型老油藏的开发具有借鉴意义。
Fault-block Mao31 in Maozhou Oilfield is a middle-deep sand reservoir in a complex fault block,which is controlled by structures and lithology.An accurate fault-block trap evaluation is the key to the reservoir development.With tools provided by GeoEast Interpretation Sub-system,minor faults are characterized in detail and block traps are delineated by the horizon tracking.On this basis,the trap evaluation is carried out.Seismic attributes such as texture and highlight volume are optimized to predict the reservoir distribution of Section Es3 of Fault-block Mao31,and the hydrocarbon content is predicted by the fluid detection.According to our research results,new channel-sands and a local structural height are discovered in the study area.Our research has achieved good results:from 4 wells proposed in the southwest of Fault-block Mao31,3 have obtained high oil production.Our practice can be a reference for similar situations.
