岩性地层油气藏勘探研究的两项核心技术

岩性地层油气藏在我国陆上油气储量和产量中都占有非常重要的地位。实践表明，该领域勘探研究的核心技术是地震储集层预测与层序地层学。地震储集层预测一般分为递推反演、测井约束反演和叠前反演三大类，应用时有条件限制。储集层特征重构是提高纵向分辨率的有效方法，地震属性解释是提高横向分辨率的重要手段。我国陆相盆地层序地层学研究主要侧重于概念的探讨和模式的提出，没有完全实现露头、钻井、测井及三维地震等多学科结合在空间上的工业化成图，针对此问题，提出了工业化应用的6个步骤。图6参13

Two key technologies about exploration of stratigraphic/lithological reservoirs

Stratigraphic/lithologic traps play a very important role in reserves and production increase in Chinese onshore exploration. It is practically proved that the key exploration technologies are reservoir prediction and sequence stratigraphy. Generally, reservoir predicting technologies can be classified as: recurrence inversion, logging restriction inversion and pre-stack inversion, which should be fit to some conditions in application. To raise vertical resolution, reservoir feature reconstruction is an effective method and seismic attribution interpretation is also very important. The application of sequence stratigraphy is affected by marine sequence framework in Chinese petroleum plays. In the past several decades, continental sequence stratigraphy didn't industrialize through the combination of outcrop, drilling and logging. So six industrialization steps for sequence stratigraphy could be effectively presented in practical exploration.
