摘要: 川东地区中二叠统茅口组普遍发育岩溶储层。基于大量野外露头、钻井岩心、薄片、测井、录井解释资料以及地震资料，对岩溶储层特征及主控因素进行综合分析。研究结果表明：（1）岩溶储层具有多种识别标志，岩心与露头上，常具有残余溶蚀孔洞与裂缝，地层顶部可见铝土质黏土岩及含褐铁矿的岩溶角砾；测井上，声波时差、补偿中子、补偿密度曲线与双侧向电阻率曲线均呈现箱型、成像测井表现为黑色斑块状；录井上，见井漏与放空；地震剖面上，呈现出“低频、强振幅、宽波峰”特征，当缝洞较多时还会出现“亮点”反射特征。（2）岩溶储层的储集岩主要为颗粒灰岩，储集空间主要为溶孔、溶洞；储层物性表现为低孔低渗的特征，孔洞型储层物性最佳；纵向上，岩溶储层主要分布在距茅口组顶部100 m范围内，孔洞型储层最为发育；横向分布延展性较差；平面上在邻水—丰都一带呈北西−南东向的带状分布。（3）颗粒滩为岩溶储层优质的物质基础，并为后期成岩流体提供渗滤通道；岩溶古地貌控制了岩溶储层分布，高产井多分布于岩溶陡坡与岩溶缓坡的残丘地貌单元中，岩溶高地与岩溶陡坡的过渡区也是岩溶储层发育的有利区；多期裂缝改善了储层的储集性能，并为油气渗滤提供通道，促进大型油气藏的聚集。故建议将茅口组中上部颗粒滩与裂缝发育的残丘地区作为下步油气勘探开发重点区。Abstract:
The middle Permian Maokou Formation in the eastern Sichuan region is characterized by the widespread development of karst reservoirs. However, systematic analysis of the identification criteria and controlling factors of these karst reservoirs remains insufficient. This study integrates extensive field outcrops, drilling cores, thin sections, well logging and well logging interpretation, and seismic data to comprehensively analyze the response characteristics of karst reservoirs in the Maokou Formation of the eastern Sichuan region. Furthermore, this paper elucidates the fundamental characteristics and distribution patterns of these reservoirs while conducting a comprehensive evaluation of their primary controlling factors. The key findings are as follows. (1) Karst reservoirs exhibit a variety of identification markers. The petrological response characteristics are as follows: residual dissolution pores, ranging from 2 mm to 70 mm in diameter, and fractures—mainly high-angle structural fractures—are generally developed in both cores and outcrops. Additionally, the caves are mostly half-filled with calcite, dolomite, or asphalt, while some remain unfilled. Bauxitic clay rocks and karst breccia containing limonite are visible at the top of the stratum, indicating the existence of ancient weathering crust. The logging response characteristics are as follows, the acoustic time difference, compensated neutron curves and compensated density curves are "box-shaped" in the karst cave section. The phenomena of pronounced acoustic time difference leap are observed, accompanied by a reduction in the positive difference of deep and shallow dual lateral resistivity. Imaging logging shows the black patchy karst cave characterized by low resistance and high conductivity. Natural gamma values in the karst cave section is generally lower than 40 API, with low content of radioactive elements. The logging response is characterized by frequent well leakage and venting during drilling, mainly occurring in the range of 0 m to 100 m from the top of the Maokou Formation. High-yield gas wells are mostly located in the second and third members of the Maokou Formation, reflecting the development of fracture-cavity reservoirs. The seismic response characteristics are marked by "low-frequency, high-amplitude, and wide-crest" reflections at the top of the Maokou Formation. In the dense area of karst caves, "bright spots" anomalies appear. The development of karst caves reduces wave impedance difference, resulting in downward-dragged and chaotic reflections. (2) The rocks of karst reservoirs are mainly composed of grain limestone. The main reservoir spaces consist of dissolved pores and caves, with caves being the most significant reservoir space, accounting for more than 65 %. These caves are predominantly distributed in isolated patterns, exhibiting poor connectivity. Dissolved pores, including intragranular, intergranular, and intercrystal types are predominantly filled. The measured porosity of the karst reservoir ranges from 2.0% to 8.7 %, with an average of 3.4 %. The permeability varies from 0.008 mD to 65.263 mD, averaging 18.3 mD, showing the characteristics of low porosity and low permeability. Among the three types of karst reservoirs, fracture-cavity reservoirs exhibit the most favorable physical properties, with a porosity of 3.3 %, and a permeability of 23.3 mD. In contrast, the cavity-type reservoirs demonstrate inferior physical properties due to the lack of filtration channels. Karst landforms are categorized into karst highlands, steep karst slopes, gentle karst slopes, and karst basins. The porosity of steep karst slopes (3.96 %) is significantly higher than that of gentle karst slopes (3.27 %) and karst highlands (2.10%). Vertically, the karst reservoirs are mainly distributed within 100 m from the top of the Maokou Formation, particularly in the Mao 2a sub-member and the Mao 3 member. These reservoirs exhibit poor lateral ductility, presenting as isolated point-like or belt-like distributions. Horizontally, there is a NW–SE zonal distribution in the Linshui–Fengdu area, with reservoir thicknesses ranging from 7.68 m to 11.04 m. (3) Karst reservoirs are influenced by the combined effects of sedimentation, karstification and tectonism. Specifically, the grain shoals (intra-platform shoals and platform margin shoals) are mainly developed in the Mao 2 and the Mao 3 members. The thickness of the granular limestone is positively correlated with the thickness of the reservoir ( R2 = 0.82 ), which indicates that the grain shoals provide a high-quality material foundation for the karst reservoirs and offer percolation channels for diagenetic fluids in later stages. The karst paleogeomorphology controls the distribution of karst reservoirs. High-yield wells are mostly located in the geomorphic units of residual mounds on steep karst slopes and gentle karst slopes. The transitional zones between karst highlands and karst steep karst slopes are also favorable areas for the development of karst reservoirs. Multiple stages of fracturing improve the reservoir storage performance. Specially, three stages of fractures came into being during the Dongwu Movement (early high-angle fractures), the Indosinian–Yanshan Movement (mid-term X-shaped fractures), and the Himalayan Movement (late horizontal fractures). The late horizontal fractures intersected the earlier fractures and connected with karst caves, significantly enhancing the permeability. For instance, the fracture density of Well W78 reached 11 fractures/m, resulting in a substantial increase in daily gas production. These fractures provide channels for oil and gas infiltration, facilitating the accumulation of large oil and gas reservoirs. (4) Based on the analysis of the dominant controlling factors, two favorable areas have been identified. The first is the Linshui–Fengdu steep karst slope zone, which is characterized by thick grain shoals reaching up to 23 m in the Mao 3 Member, the well-developed residual mound landform, dense karst caves and fractures, all of which contribute to optimal reservoir physical properties. The second is the Dazhou–Kaijiang gentle karst slope zone. This zone features the superposition of multi-stage fractures, particularly med-term fractures, which significantly enhance permeability. Although karstification is relatively weak, this area has the potential of high-yield production. -
