摘要

摘要: 近年来，四川盆地多口井在中二叠统茅口组一段(茅一段)(含)泥灰岩地层中钻获工业气流，展示出良好的勘探潜力。早期研究认为，茅一段(含)泥灰岩具有自生自储的特征，是一套低孔、低渗的裂缝—孔隙型致密碳酸盐岩储层，储集空间多样，海泡石向滑石转化过程中形成的成岩收缩孔缝对储集空间贡献较大。为进一步探讨茅一段黏土矿物的成因及其储集意义，采集川南6口钻井和1条野外剖面的茅一段岩样，通过显微镜、氩离子电镜、X射线衍射(XRD)、主微量元素、锶同位素(⁸⁷Sr/⁸⁶Sr)、孔隙度、氮气吸附等实验手段，对茅一段(含)泥灰岩中黏土矿物进行研究。镜下观察与XRD结果显示，川南茅一段黏土矿物多以基质、不规则斑块(点)状和交代钙质生物壳体等形式产出，以滑石、富镁蒙脱石等镁质黏土矿物为主，含少量海泡石。此外，茅一段(含)泥灰岩的Al₂O₃含量、ΣREE含量较低，Y/Ho比值和⁸⁷Sr/⁸⁶Sr值类似于同期海水，表明陆源输入的碎屑少，茅一段镁质黏土矿物最初(海泡石阶段)为沉积—早成岩期形成的自生黏土。茅一段储层的孔隙度/孔容与黏土矿物总量、富镁蒙脱石含量呈正相关，与滑石含量无明显相关性，甚至轻微负相关，表明川南茅一段泥灰岩储层的储集空间受黏土总含量及成岩演化阶段影响。孔隙空间整体随黏土含量增多而增大，热演化处于成熟—高成熟阶段，黏土矿物以富镁蒙脱石为主时，黏土孔缝发育，储集物性好；过高的成岩演化(热演化处于过成熟阶段，滑石化程度高)不利于孔隙的发育。

Abstract: In recent years, multiple wells in the Sichuan Basin have produced industrial gas from the marlstone/marl-bearing limestone strata in the first member of the Middle Permian Maokou Formation (Mao 1), demonstrating promising exploration potential. Previous studies have suggested that the marlstone/marl-bearing limestone in Mao 1 exhibits self-generation and self-storage characteristics, forming low-porosity, low-permeability fracture-porosity type tight carbonate reservoirs with diverse storage spaces. Notably, diagenetic shrinkage pores and fractures formed during the transformation of sepiolite to talc contribute significantly to the storage space. To further investigate the genesis of clay minerals in Mao 1 and their significance for reservoir storage, rock samples were collected from six wells and one outcrop in the southern Sichuan Basin. A series of analyses, including microscopy, argon ion microscopy, X-ray diffraction (XRD), major and trace element analysis, strontium isotopic ratios (⁸⁷Sr/⁸⁶Sr), porosity tests, and nitrogen (N₂) adsorption experiments, were conducted to study the characteristics of clay minerals in the marlstone/marl-bearing limestone of Mao 1. Microscopic observations and XRD results showed that the clay minerals mainly occurred as matrix minerals, irregular patches/spots, and replacements of biogenic calcareous shells. These minerals were primarily magnesian clay minerals such as talc and magnesium-rich montmorillonite, with minor amounts of sepiolite. Additionally, the marlstone/marl-bearing limestone in Mao 1 had relatively low Al₂O₃ contents and ΣREE concentrations, and its Y/Ho ratios and ⁸⁷Sr/⁸⁶Sr values resembled those of contemporaneous seawater, indicating limited terrigenous clastic input. This suggested that the magnesian clay minerals were originally authigenic clays formed during the deposition-early diagenesis period (in the sepiolite stage). The porosity/pore volume of the reservoir was positively correlated with the total clay mineral content and the magnesium-rich montmorillonite content, but no significant correlation or even a slight negative correlation was observed with the talc content. This indicated that the storage space in the marlstone reservoir was affected by the total clay content and the diagenetic evolution stage. The overall pore space increased with higher clay content. When thermal evolution was at the mature to highly mature stage and magnesium-rich montmorillonite was dominant, clay pores and fractures were developed, enhancing reservoir properties. However, excessive diagenetic evolution (over-mature thermal stage with higher talc content) was unfavorable for pore development.
