陆相致密砂岩薄互储层正反演定性识别技术研究

摘要

How to identify and character accurately of thin interbedded reservoir has always been the goal of the geophysicist. Based on rock physics analysis and the forward and inversion of model, the qualitative analysis of the reservoir’s recognition ability in Qikeshu oilfield of Lishu fault depression were carried out, followed by stochastic inversion and stochastic simulation. Combina⁃tion of the forward and inversion results to identify and character the target reservoir play an important role in the exploration and development of the tight sandstone reservoir and provide important basis for the reserve calculation in this area.%如何准确地对薄互储层进行识别刻画一直是勘探开发物探解释人员研究的目标。通过以储层的岩石物理分析、模型正反演研究为基础，定性分析梨树断陷七棵树油田储层的识别能力，从而进行随机反演和随机模拟。结合正、反演的结果对目的储层进行识别刻画，在该地区致密砂岩储层的勘探开发中起到关键性的作用，为该地区的储量计算提供了重要依据。
