摘要

升平气田白垩系营城组火山岩主要为流纹岩、安山岩、玄武岩、霏细岩及火山碎屑岩。不同岩石类型的测井曲线响应特征不同。火山岩地震反射特征主要为强振幅、视低频 ,而且连续性差。火山岩主要储集空间为孔隙 ,裂缝的存在改善了火山岩的渗流能力。该区内火山岩相主要为火山爆发相、溢流相。地震地质模式以中心式喷发模式和多次喷发模式为主。利用波阻抗反演可以有效地识别火山岩体 ,并进行储层的横向预测及含气面积圈定
Yingcheng group's volcanic rocks in Shengping gas field are composed of rhyolites, andesites, basalts, felsites and volcanic fragmental rocks. The responsing characteristics of log curves of different rock types are different. The seismic reflection characteristics of volcanic rocks are mostly strong amplitude, apparent low frequency and the continuity is bad. Volcanic rock's storing space is mainly pore, and the fissure's existing greatly improves the volcanic rock's seepage ability. The volcanic lithofacies in this field are mainly erupting facies and flowing facies. Seismic geological models are mainly composed of central erupting model and multi erupting model. By using of wave impedance reversion to identify the volcanic rock, we have forecasted the reservoir bed's transverse distribution and traped the containing gas area.
