摘要

综合利用岩心、测井和分析测试等多种方法,识别并划分了四川盆地新场地区三叠系须家河组二段有利岩石相类型,建立了有利岩石相标准,揭示了其平面分布规律,探讨了有利岩石相形成机制及其对产能的控制作用。结果表明:①新场须二段共发育12种岩石相类型,其中“千层饼”/平行层理、块状层理、斜层理和含炭屑中粗砂岩岩石相物性好、含气性高,是有利岩石相类型,测井呈现“三低一高”特征,即低自然伽马、低中子孔隙度、低电阻率、高声波时差;②沉积作用决定了砂体空间展布,是有利岩石相形成的物质基础,后生成岩流体对有利岩石相的形成起到了差异性改造的作用,构造活动和深层异常地层压力使地层沿薄弱面发生顺层滑动,导致不同岩石相形成裂缝,储集层渗透性得到有效改善;③有利岩石相发育程度是决定气井稳产能力的主要因素。图11表2参33

Abstract

By using core, logging curves, and experiment data, favorable lithofacies types in the 2nd Member of Triassic Xujiahe Formation in the Xinchang area, Sichuan Basin were classified, standard of the favorable lithofacies was established, planar distribution regularities of the favorable lithofacies were identified, and forming mechanisms of the favorable lithofacies and their control effect on production were examined. (1) The 2nd Member of Xujiahe Formation has twelve types of lithofacies, among which multiple layer medium-coarse grain sandstone lithofacies, parallel bedding medium-coarse grain sandstone lithofacies, massive medium-coarse grain sandstone lithofacies, cross bedding medium-coarse grain sandstone lithofacies, and carbonic medium-coarse grain sandstone lithofacies with better physical properties and higher gas content are favorable lithofacies; they feature low GR, low CNL, low RT, and high AC on logging curves. (2) The sedimentary process controls spatial distribution of sand bodies which are the material basis of the favorable lithofacies; post diagenetic fluids would differentially reconstruct the favorable lithofacies; tectonic activities and abnormal formation pressure made strata slide along the weakness plane, giving rise to fractures in different types of rocks, which can enhance the reservoir permeability significantly. (3) The development degree of favorable lithofacies is a major factor affecting stable production of gas well.
