摘要/Abstract

摘要： 吐哈盆地台北凹陷中—下侏罗统煤系碎屑岩地层含铁碳酸盐矿物广泛分布、储层非均质性强，不同地区油气富集特征差异较大。综合多种测试手段，重点针对储层中的碳酸盐矿物及共生矿物开展系统研究，揭示其对储层非均质性的影响机理。结果表明，含铁碳酸盐不同程度地充填孔隙是导致储层孔隙度降低和非均质性增强的重要原因，其分布同时受与沉积作用有关的砂体厚度、颗粒粒径、碎屑组分以及杂基含量的影响；辫状河水下分流河道砂岩在丘东洼陷表现为砂体厚度大、粒度较粗、岩屑类型复杂而杂基数量有限，在胜北洼陷则表现为砂体厚度较薄、粒度较细、塑性岩屑及杂基含量均较高；复杂的碎屑组分及较高的杂基含量为含铁碳酸盐矿物的形成奠定了物质基础，岩石结构、有机质的数量及变化决定了储层成岩演化路径，并进一步导致与含铁碳酸盐有关的矿物组合的时空差异。

Abstract: The clastic rocks in the Middle-Lower Jurassic coal strata measures are important target for oil and gas exploration and development in Taibei Sag, Turpan-Hami Basin. Iron-bearing carbonate minerals are wildly distributed and the reservoir heterogeneity is strong. In addition, there are significant differences of oil and gas accumulation in different areas. Using various analysis testing. We make a systematic study on the carbonate minerals and paragenetic mineral in the reservoirs and clarify the main causes of reservoir heterogeneity. The study shows that the pores are filled by carbonate minerals to different extent, leading to the decrease of reservoir porosity and the enhancement of heterogeneity reservoir. The mineral assemblage and distribution are affected by the thickness, grain size and composition of sandstone related to sedimentation. The sandstone grain size of underwater distributary channel of braided river in Qiudong Depression is thick, coarse with complex debris and matrix content is poor. The sandstone of underwater distributary channel of braided river in Shengbei Depression is of thin-thickness, of fine grains with high content of plastic debris and matrix. Complex clastic components and high matrix content in sandstone lay the material foundation for the formation of iron-bearing carbonate minerals. The rock texture and quantity of organic matter in sediments determine the diagenetic evolutionary path of reservoirs in different intervals, and further lead to the spatial and temporal disparities of the mineral assemblage associated with iron carbonates.
