    Gas and Water Pay Recognition of Water-Producing Reservoir with Low Permeability and Resistivity: A Case from the Xujiahe Formation in Guang'an Gasfield of Sichuan Basin, Southwestern China

    • 摘要: 广安气田上三叠统须四段和须六段气藏发育了构造气藏、构造-岩性气藏和岩性气藏.储层具有低孔、低渗、低阻和高束缚水饱和度特征.空间上,储层孔渗相关关系变化大,气水分布复杂,气水层识别困难.根据岩心对测井的标定,研究了须四段和须六段四性关系,认识到储层为细砂岩、中砂岩和粗砂岩,具有低自然伽马、低补偿密度、低电阻率和高声波时差特征,而物性与含气性无明显相关性.采取了分层、分区块建立储层孔隙度、渗透率模型,提高了物性解释精度.不同气藏类型具有不同的气水分布,应用阵列感应、核磁共振和综合判识3种方法进行了气水层识别,提高了广安气田气水层识别精度.这些方法在广安气田的应用表明可以准确识别构造气藏和构造-岩性气藏的气、水层,但对构造幅度低的岩性气藏识别精度不高,因为在这些岩性气藏中气水分异不彻底,气层与气水同层、水层含水饱和度是渐变的.
