摘　　要：根据苏里格地区致密砂岩储层的横波测井资料开展岩石物理分析与AVO正演;进行纵波、转换波资料联合标定,改进了在模型正演控制下的纵波、转换波匹配方法;利用多分量资料属性分析技术定性预测了主要目标层段储层物性与含气性的变化;开展了基于各向异性理论的多分量叠前联合反演,半定量地预测有效砂体分布。对苏里格地区实际资料的研究,降低了纵波地震技术的多解性。Rock physical analysis and AVO forward modeling of the transverse wave logging data of the tight sandstone reservoir in Su- lige area were carried out;the combined calibration method of longitudinal wave and converted wave data was studied, and a matching method of longitudinal wave with converted wave under the control of model forward is presented;the variation of the physical properties and the gas-bearing properties of the main target strata in the study area was qualitatively predicted using the attribute analysis tech- nique of multi-component data; the multi-component pre-stack inversion based on anisotropic theory is developed, and the effective sand- body distribution is semi-quantitatively predicted. The study of the actual data of Sulige area reduces the multi-solution performance of P-wave seismic technology.
