【摘要】 广安气田处于开发初期,气井产水多,产能低。针对该气田储层低孔隙度、低渗透率及高含水饱和度的特点,从深盆气藏的地质特征出发,采用地质类比法和气藏数值模拟法,探寻该地区须家河组气藏的深盆气可能性。研究结果表明,须家河组须四气藏初步具有深盆气的特征,应处于深盆气的气水过渡带,而须六气藏不具有深盆气的特征,属常规气藏。更多还原

【Abstract】 Guang’an gas field is in the early stages of development and there are some geological conditions uncertain.Gas well produces abundance water,which has great influence on its deliverability,so the deliverability is low.Targeted with the characteristics of low porosity,low permeability and high water saturation of this gas field,this article bases on the geological characteristics of deep basin gas reservoir and adopts geological analogical analysis and numerical reservoir simulation method to try to assume the possibility of deep basin gas of Xujiahe gas reservoir in Guang’an.The result shows that Xu-4 gas reservoir of Xujiahe gas reservoir has preliminary characteristics of deep basin gas,which should be in the transitional zones of deep basin gas accumulations.But Xu-6 gas reservoir of Xujiahe gas reservoir is a convention gas reservoir.更多还原
