塔河东南部碳酸盐岩凝析气藏储层描述技术与潜力

Reservoir Description Technology and Potential of Carbonate Gas Condensate Reservoir in Southeast of Tahe

塔河油田东南部奥陶系为碳酸盐岩缝洞型凝析气藏,具有一定的特殊性,如何研究落实碳酸盐岩有利储层分布状况是开发工作中的难点。本文通过断裂特征研究、趋势面分析技术、有利地震反射特征识别及振幅变化率分析,明确了塔河东南部奥陶系碳酸盐岩有利储层分布特征,形成了适合该地区的碳酸盐岩凝析气藏储层描述技术,对塔河东南部碳酸盐岩凝析气藏投入滚动产能建设具有重要的作用。

Oilfield ordovician reservoir in the southeastern of Tahe is the carbonate fractured-vuggy type condensate gas reservoir,it has some special characteristics,and how to study the distribution of favorable reservoirs in carbonate rocks is a difficult problem in the development work.In this paper,we use fracture characteristics research,trend surface analysis technology,favorable seismic reflection feature recognition and the amplitude variation analysis,the favorable reservoir distribution characteristics of the ordovician carbonate rocks in the southeast of Tahe are defined.The reservoir description technology of carbonate gas condensate reservoir in the area is determined,which plays an important role in the construction of the rolling capacity of the carbonate condensate gas reservoir in the southeast of Tahe.
