摘要: 塔里木盆地致密砂岩油气的勘探面积广阔、资源量大、探明程度较低,烃源灶分布、复杂储层预测和油气成藏模式等问题制约了致密油气藏的整体效益勘探开发。基于露头剖面、实验分析、地球物理和测井测试等资料,对塔里木盆地前陆区和台盆区致密砂岩油气藏的新领域和资源潜力开展了详细分析。研究结果表明:库车坳陷致密砂岩油气新领域主要为白垩系亚格列木组中层—厚层含砾砂岩和中侏罗统克孜勒努尔组中层—厚层砂岩,构造-岩性油气藏在纵向上邻近侏罗系—三叠系烃源岩,在横向上毗邻克拉苏构造带生烃中心;塔西南昆仑山前致密砂岩油气藏新领域主要为二叠系普斯格组中层—薄层砂岩,构造-岩性油气藏在纵向上紧邻普斯格组上段优质烃源岩,在横向上毗邻柯东构造带生烃中心;台盆区致密砂岩油气藏新领域主要为志留系柯坪塔格组中层—薄层砂岩,构造-岩性油气藏在纵向上通过深大断裂输导由寒武系—奥陶系优质烃源岩生成的油气,在横向上毗邻阿瓦提凹陷生烃中心。库车坳陷克拉苏构造带北翼和东秋—迪那构造带致密油气藏圈闭的累计面积为1 830 km2,天然气的资源量为16 625×108m3;塔西南坳陷柯东构造带致密油气的有利圈闭面积近301 km2,预测天然气的地质资源量为2 930×108m3、凝析油的地质资源量为 2×108t;阿瓦提凹陷西北缘柯坪塔格组致密油气的有利勘探区面积达4 320 km2,预测天然气资源量为7 076×108m3、石油资源量为7 817×104t。塔里木盆地致密油气勘探新领域和资源潜力可为盆地的持续高效勘探夯实基础。

Abstract: The tight sandstone oil and gas in Tarim Basin is characterized with wide exploration area, large-scale reserves, and low proportion of proved reserves, and also faces the problems of hydrocarbon source distribution, complex reservoir prediction, as well as oil and gas accumulation mode, which restrict the overall profitable exploration and development of tight reservoirs. Based on outcrop profile, experimental analysis, geophysical and well logging data, a detailed analysis is performed on the new fields and resource potential of tight sandstone reservoirs in forelands and basins. The results show that the new fields of tight sandstone oil and gas in Kuqa depression are dominated by the medium to thick gravel sandstones of the Cretaceous Yageliemu Formation and the medium to thick sandstones of the Middle Jurassic Kezilenuer Formation, forming the structural-lithologic reservoirs longitudinally adjacent to high-quality source rocks in the Upper Member of Pusige Formation, and transversely adjacent to structural-lithological hydrocarbon reservoirs in the hydrocarbon generating center of Awati sag. In the north wing of the Kelasu structural belt and the Dongqiu-Dina structural belt in Kuqa depression, the cumulative area of tight oil and gas traps is 1 830 km2 for tight oil and gas, and the predicted natural gas resource is 16 625×108m3. The favorable trap area of tight oil and gas in Kedong structural belt of southwest depression of Tarim Basin is 301 square kilometers, and the natural gas geological resources are estimated to be about 2 930×108m3 and the condensate oil geological resources are about 2×108t. The favorable area of tight oil and gas in Kepingtage Formation in the northwest margin of Awati sag is 4 320 km2, the natural gas resources are estimated to be 7 076×108m3, and oil resources are 7 817×104t. New fields and resource potential provide a solid foundation for sustained and efficient hydrocarbon exploration.
