摘要

开发地震技术是近年来在油藏滚动勘探和开发过程中广泛应用的一项石油物探综合技术 ,其特点之一是将三维地震数据体在测井约束下反演成为与油藏实际情况相吻合的三维孔隙度体 ,并结合三维可视化技术直观地解剖油藏内幕。将珠江口盆地惠州油田群 180km2 三维地震数据体在 4 0余口钻井约束下反演成三维孔隙度体 ,利用三维可视化技术对主力油藏进行了精细描述 ,结合油藏动态设计了 5口侧钻井方案用以开发剩余油藏和动用未动用储量。已钻井结果与预测结果基本吻合 ,从而有效地指导了该油田群进一步的勘探开发
Production seismics is an integrated geophysical technique which has been widely used in rolling exploration and development of reservoirs in recent years. Under constraint of logging data, this technique can invert 3D seismic data into a porosity cube in accordance with the actual reservoir, thus directly revealing the interior characteristics of reservoirs by using the 3D visualization techniques. For the Huizhou group of oilfields in Pearl River Mouth Basin, 180km 2 3D seismic data have been inverted into porosity cubes under constraint of 40 wells, and the main reservoirs are refinedly described using the 3D visualization techniques. In combination with reservoir performance, a program of 5 sidetrack drilling is designed to recover the remaining reservoirs and untapped reserves within the developed reservoirs. The drilling results are largely in accordance with prediction from this study, thus guiding further exploration and development of the oilfield group.
