| 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.

| Abstract: | The fourth and sixth members of upper Triassic Xujiahe Formation develop structural,structural-lithological and lithological reservoirs with characteristics of low porosity,permeability,resistivity and high irreducible water saturation in Guang'an gasfield of Sichuan basin,southwestern China.In space,relationship of the reservoir porosity and permeability varies greatly,and the reservoir gas and water distribution is complex,resulting in difficulty in gas and water pay recognition.Based on the core calibrat... |
