摘要
垦71开发区块具有被断层复杂化的多油水系统,储层厚度薄,横向关系复杂,储层与非储层速度差异小,后续开发方案调整所要求的精细储层描述难度较大。我们利用多井地震、地质标定、三维构造解释成果建立三维多断层精细约束地质模型,在此基础上采用随机地震反演方法进行波阻抗、岩性等多种地层参数反演,使储层精细描述达到了较高的精度。
The oil-water systems are in Ken 71 area. The thin reservoirs complicated by the faults thickness, complex horizontal relationship and a little bit of the difference in velocity between the reservoir beds and non-reservoir beds make us difficult to describe reservoirs finely to meet the requirement of the new development plan. A 3D multiple fault fine constraint geologic model are established from multiple well seismic, geologic calibration and 3D structure interpretation, based on it, then the multiple formation parameters, such as impedance and lithology, were inverted by random seismic inversion, and got a high description precision.
