致密油气藏地震资料反演的混合建模与基础算法

Tight oil and gas reservoirs are the primary targets of the second generation of oil exploration and development, they are the best hope to solve the problems of energy shortages in our country, but the tight oil and gas reservoirs exploration and development technique hasn't been fully developed yet, it faces many great challenges. This project is set in tight oil and gas reservoirs of loess plateau in Ordos Basin, focus on the key scientific problem of finely characterization of the tight oil and gas reservoirs using the observation data in geophysics, the aim is to build multi-scale, multi-physics coupled models which can characterize the geometry, reservoirs characteristics and fluid properties of the non-conventional oil and gas reservoirs, develop the corresponding modeling and inversion theory and method about the non-conventional oil and gas reservoirs, form unconventional oil and gas reservoirs characterization and monitor technology based on seismic observed data information processing; and then combine multi-scale multi-physics wave field simulation inversion with the inversion based on seismic observed data information processing to develop hybrid modeling inversion theory and basic algorithm on unconventional oil and gas reservoirs characterization and monitor. The developed theory and methods will be applied to tight oil and gas reservoirs exploration and development in Ordos Basin loess plateau.

致密油气藏是我国第二代石油勘探与开发的主要对象, 是解决我国石油能源短缺问题的希望所在。但致密油气藏勘探开发技术尚未成熟, 面临一系列重大挑战。本项目以鄂尔多斯盆地黄土塬地区致密油气藏为背景，聚焦研究“利用地球物理观测数据对致密油气储层精细刻画”这一关键科学问题，旨在建立能够刻画非常规油气储层几何结构、储集特征、流体性质的多尺度多物理耦合模型，发展相应的非常规油气储层的正、反演理论与方法；形成基于地震观察数据信息处理的非常规油气储层刻画与监测技术；进而结合基于复杂介质中多尺度多物理波场模拟的反演与基于地震观察数据信息处理的反演，发展非常规油气储层刻画与检测的混合建模反演理论与基础算法。所发展的理论与方法将应用于鄂尔多斯盆地黄土塬地区致密油气藏勘探实践。
