油气田开发地质学:发展趋势与策略

PETROLEUM DEVELOPMENT GEOLOGY:ADVANCEMENTS AND STRATIGY

作为现代石油地质学与油气田开发工程的交叉学科 ,油气田开发地质学为提高油气田开发水平及技术应用效果发挥了重要作用。未来油气藏描述技术将以快速获得油气藏各尺度下的三维结构动态变化信息为目标 ,对油气藏物理化学、地球化学性质的变化及评价、控制技术的需求将更加迫切。剩余油分布理论及预测技术、油气藏开发演变理论与控制工程将大有所为。复杂油气藏的认识将更多的依赖于地质力学、岩石物理学、界面化学、粘土矿物学、纳米科学与技术。文章讨论了学科中长期发展目标和战略任务 ,指出油气藏岩石物理学、油气藏开发地球化学、非常规天然气开发地质学、油气藏描述及开发地质建模、剩余油分布理论及开发工程是优先重点发展领域 ,强调必须狠抓典型基地建设 。

Petroleum development geology, as a cross discipline combined modern petroleum geology with petroleum development engineering, has played an important role in improvement of petroleum field development and technology application. The object of reservoir characterization in the future is acquiring information of 3D dynamic structures of reservoir in time. Reservoir characterization necessitates evaluation methods and control techniques of reservoir properties on physical-chemistry and geochemistry. Residual oil distribution and prediction, reservoir evolution theory and control engineering during petroleum field development will be found more application. Understanding and description of complicated reservoirs will be increasingly relied on geomechanics, petrophysics, interfical chemistry,clay mineralogy, nanometer science and technology. The paper has discussed the middle and long term development targets and strategically tasks of the discipline. And it has suggested that reservoir petrophysics, reservoir development geochemistry, development geology for unconventional gas, reservoir characterization and geological modeling, residual oil distribution theory and development engineering are priority development fields. It also emphasizes that much attention should be paid on the construction of typical study base and establishing long and stable base for theory and new technology innovations.
