致密储层流体因子的构建及地震预测方法

Methods of Modeling and Prediction a Fluid Factor for Dense Reservoir

摘要: 当前各个油气主力富集区逐渐进入开发中后期，寻找新的产能接替区已迫在眉睫。如何在保证效益的前提下，高效的开发新增资源已变成多数油气田的瓶颈，这也对储层描述技术提出了更高的要求。针对致密碎屑岩的储层精细描述难题，通过致密层岩石物理分析，构建一种更为敏感的流体因子进行地震预测，并采用叠前空变反演提高横向精度，实现了龙凤山地区碎屑岩储层精细描述和开发水平井部署。

Abstract: At present, the main oil and gas enrichment areas are gradually entering the middle and late stages of development, and it is urgent to find new capacity replacement areas. Under the premise of ensuring efficiency, effective development of new resources has become the bottleneck of most of the oil and gas fields, which also for reservoir description technology put forward higher requirements. This paper in order to solve the problem of fine reservoir description of tight clastic rocks, a more sensitive fluid factor is constructed for seismic prediction through dense rock petrophysical analysis. At the same time, the paper also uses prestack airspace inversion to improve the lateral accuracy, and realizes the fine description of the clastic reservoir in Longfengshan area and the development of horizontal well deployment.
