摘要:

四川盆地广安气田须家河组气藏内气水关系复杂,须四段、须六段气藏各区块产能差异大,对比研究须四段、须六段的气水分布对该致密砂岩气藏的高效开发有重要指导意义。根据广安致密砂岩气田气水层解释难度大的研究现状,提出了一种适合须四段、须六段气水层的解释方法。首先,分段建立须四段、须六段不同类型储层的含水饱和度计算模型,再联合核磁共振与相渗资料求取束缚水饱和度,进一步计算可动水饱和度,结合生产动态资料划分出研究区须四段、须六段气水层的定量识别标准。在广安气田须四段、须六段气水层平面、剖面分布特征识别的基础上进行对比研究,结果显示须四段为大面积气水同层分布,而须六段发育高产“甜点”区,并深入探讨了二者气水分布差异主控因素。表明气源条件差异使得须四段、须六段储层内气藏原始充满程度不一;须四段、须六段储层的构成特征控制着流体的空间分布差异;构造幅度的差异使得须四段、须六段内气水分异呈现不同的分布格局。

Abstract:

The distribution of gas and water is complex in the Xujiahe Formation of Guang’an Gasfield.The production capacity is different in various blocks of Xu4 and Xu6  Formations.So it has a great meaning to analyze the distribution of gas and water for the efficient development of Guang’an Gasfield.A proper method was proposed to identify the distribution of gas and water.In the first place,the water saturation interpretation model was established by the core analysis.And the mobile water saturation was counted by the irreducible one,which was obtained from NMR and relative permeability curve data.Finally,the identification standards of gas and water layers were built by combining production data.Then gas and water distribution were compared between Xu6 and Xu4 Formations.The result shows that a large area of gas reservoir bearing with water is found in Xu4 Formation,while sweet spots develop in Xu6 Formation.What is more,the main controlling factors are analyzed on account of gas and water layers recognition.It shows that the gas source difference makes the fullness ratio of reservoir in Xu6 and Xu4 Formations different.The reservoir constituent differences control the hydrocarbon distribution in Xu6 and Xu4 Formations.The structure differences provide the diverse differentiation of gas and water in Xu6 and Xu4 Formations.

Key words: Difference analysis, Distribution of gas and water, Xu4 Formation, Xu6 Formation, Guang’an Gasfield
