松辽盆地汪家屯地区营城组火成岩储层含气性预测
|
摘要
汪家屯地区营城组为火成岩地层具有整体不连续,延伸范围小、相变较快、断层发育、构造破碎等特点,加之营城组地震资料品质影响,使储层预测难度进一步增大。根据以上特点,建立了一套适合该区地质特征的AVO储层预测方法,并对该区含气性进行了评价,划分了有利储层发育带及有利含气储集带。所得到的含气性预测结果对该区的天然气勘探开发具有重要指导作用。
The YingCheng Formation in Wangjiatun area are igneous rock,it features as discontinuous,small extending range,frequent facies changes,fault development|,structural fractured and so on.And it brings a larger difficulty to reservoir interpretation and prediction affected by seismic data quality.According to those characteristics,we establish a set of AVO reservoir prediction methods which is suit for the geological charactenistics of this region.,and evaluate gas bearing capacity of this region,divide the beneficial reservoir growth zones and gas accumulation zone.The obtained gas-bearing reservoir prediction result perform an important function for natural gas exploration and development in this erea.
