塔里木盆地盐下超深层碳酸盐岩岩石力学数据

塔里木盆地盐下超深层碳酸盐岩岩石力学数据主要面向油气勘探需求，采集塔里木盆地盐下超深层油气藏盖层岩石样品，对不同岩性盖层平均突破压力、盖层岩性组合类型进行了统计分析对比，结合文献调研，对不同盆地不同层系盖层的力学性质进行了统计，包括岩性、围压、温度、应变-强度极限（%）、屈服极限、强度极限、残余强度、深度、地区、层位、井名等信息，共收集到202项数据；同时开展岩石增幅三轴力学测试、盖层岩石破裂数值模拟，综合分析，得到塔里木盆地寒武系膏盐岩盖层、断裂、油气分布综合分析图1幅、塔里木盆地寒武系膏盐岩类盖层封闭能力等值线图1幅、塔里木盆地中寒武岩性组合分布图1幅，数据量26.4MB。The pre-salt ultra-deep carbonate rock mechanics dataset of the Tarim Basin is primarily developed for oil and gas exploration demands. Rock samples of caprocks from pre-salt ultra-deep oil and gas reservoirs in the Tarim Basin were collected, and statistical analysis and comparison were performed on the average breakthrough pressure of caprocks with different lithologies and the lithologic association types of caprocks. Combined with literature review, statistical analysis was conducted on the mechanical properties of caprocks from different basins and stratigraphic sequences. The dataset covers information including lithology, confining pressure, temperature, strain-strength limit (%), yield strength, ultimate strength, residual strength, burial depth, region, horizon, well name, etc., with a total of 202 valid data entries. Meanwhile, incremental triaxial mechanical tests on rock samples and numerical simulation of caprock fracture were carried out. Through comprehensive analysis, one comprehensive analysis map of Cambrian gypsum-salt caprocks, faults and oil-gas distribution in the Tarim Basin, one contour map of sealing capacity of Cambrian gypsum-salt caprocks in the Tarim Basin, and one distribution map of Middle Cambrian lithologic associations in the Tarim Basin were generated. The total size of the dataset is 26.4 MB.
