摘要:
珠江口盆地东部YP油区不同油田主力油藏均为断层圈闭油藏，断层引起的地层横向速度变化导致该区地震资料大量存在断层影响畸变成像区，给该区构造评价带来挑战。传统解决断层阴影一般采用多方位或宽方位地震资料重采集或针对断层成像的目标性处理等，其涉及采集费用高，处理周期长。本文提出利用地层倾角属性定量刻画断层阴影带范围，然后再结合YP油区海相地层横向分布稳定的地质特征，引入支持向量回归算法计算该区高精度非线性构造趋势面，在该趋势面的约束下完成对断层阴影带畸变区域构造进行重新恢复预测。理论模型试算和YP油区某油田实例均显示该方法有较大应用潜力。
Abstract:
The main reservoirs in different fields in the YP oil region of the eastern Pearl River Estuary Basin are all fault-locked reservoirs. A large amount of seismic data in this area has fault-influenced distortion imaging zones，which poses a challenge to the tectonic evaluation of the area. Traditional solutions to fault shadows generally use reacquisition of multi-directional seismic data or targeted processing for fault imaging，which involves the acquisition of high cost and long processing cycle. This paper proposed to quantitatively depict the shadow zone range of faults using 3D stratigraphic dip attributes，and then combired it with the lateral distribution of marine stratigraphy features in the YP oil region. the paper introduced a support vector regression algorithm to calculate a high-precision nonlinear tectonic trend surface in the area. Under the constraint of this trend surface，the paper completed the prediction of distortion area structure of the fault shadow zone. The theoretical model test calculations and the production application of an oil field in the YP oil region show that the method has a great potential for application.
