| 摘 要： | 对研究区测井、地震和地质资料分析表明．含气砂体的测井响应模式为低波阻抗、中低伽马、中高电阻率．其地震响应为低频强振幅．沉积相主要为三角洲前缘河口砂坝。通过对测井约束地震反演得到的波阻抗数据体分析，预测出含气砂体分布模型；然后以此含气砂体模型为相控制条件．在分析孔隙度数据变差函数基础上．利用序贯高斯同位协克里金模拟方法建立了储层物性参数模型。生产开发实践验证了该方法建立的砂体分布模型和物性参数模型的可靠性。 |

| Abstract: | Analyzing well logging, seismic and geologic data in the studied area indicates that the logging response modes of an oil-bearing sandbody are low wave impedance, mid-low gamma ray and mid-high resistivity, its seismic response is low frequency and high amplitude, its sedimentary facies is mainly a delta frontal channel mouth bar. Through analyzing the wave impedance data volume obtained from logging constrain seismic inversion, a model of gas-bearing sandbody is predicted, which is used as conditions of facies control, a reservoir physical parameter model is established by using sequence Gauss collocated cokriging simulation on the basis of analyzing variation function of porosity data. The reliabilities of a sandbody distribution model and a physical parameter model established with the simulation method are proven in production. |
| Keywords: | seismic inversion wave impedance reservoir reservoir modeling sedimentary facies reservoir physical property |
