摘要

摘要:
柴达木盆地西部干柴沟区块C902井在古近系下干柴沟组上段Ⅳ~Ⅵ油层组获得高产油气流, 实现了柴达木盆地古近系页岩油的重大勘探突破。然而, 古近系页岩油的评价标准和资源潜力不清等问题制约了干柴沟区块高效开发。基于C902井及其他探井的勘探成果, 利用岩性、物性、孔隙结构、生烃潜力等资料, 综合评价了干柴沟区块古近系下干柴沟组上段Ⅳ~Ⅵ油层组页岩油的勘探潜力。结果表明, 该套页岩层系混积特征明显, 岩相类型包括纹层状和层状灰云岩、纹层状和层状云灰岩、纹层状黏土质页岩和层状泥岩, 具有较高脆性指数, 可压性强; 晶间孔和纹层缝是重要的储集空间, 占比达85%, 属于低孔-特低渗储层; w(TOC)均值高于0.9%, 氯仿沥青“A”和S₁+S₂共同指示生烃潜力大, 且有机质类型以Ⅰ~Ⅱ₁型为主。因此, 下干柴沟组上段Ⅳ~Ⅵ油层组具有烃源岩品质好、源储一体、可压性强、发育广泛等特征, 生储盖组合在空间上广泛发育且密封性好, 有利于压裂改造后提高油气采收率, 对干柴沟区块页岩油的高效开发具有重要理论指导意义。

Abstract: Objective
Well C902, located in the Ganchaigou area of the western Qaidam Basin, achieved a breakthrough in shale oil exploration as indicated by the high-production oil flow in the Ⅳ-Ⅵ layers of the Upper Member of the Palaeogene Xiaganchaigou Formation. However, ambiguities in evaluation criteria and resource potential limit the efficiency of shale oil development in the Upper Member of the Xiaganchaigou Formation in the Ganchaigou area.
Methods
Thus, the exploration potential of shale oil in the Ⅳ-Ⅵ layers of the Upper Member of the Xiaganchaigou Formation in the Ganchaigou area was comprehensively evaluated by comparing the lithology, physical properties, pore structure, and organic geochemistry between Well C902 and other wells.
Results
The complicated lithofacies of laminar/lamellar dolostone, laminar/lamellar limestone, laminar clay shale, and lamellar mudstone suggest the mixed carbonate and siliciclastic deposition of the Ⅳ-Ⅵ layers. The high brittleness index implies the good fracability of the Ⅳ-Ⅵ layers. The intergranular pores and laminar fractures, with a total proportion of 85% in the pore system, were dominant in the Ⅳ-Ⅵ layers that can be roughly classified as low-porosity and ultralow-permeability reservoirs. The organic matter, dominated by type Ⅰ-Ⅱ₁, shows an average TOC content of more than 0.9% in the Ⅳ-Ⅵ layers. Both chloroform asphalt "A" and S₁+S₂ indicate a high hydrocarbon generation capacity.
Conclusion
Summarily, the widely deposited the Ⅳ-Ⅵ layers of the Upper Member of the Xiaganchaigou Formation have the characteristic of source-reservoir integration and show not only good quality of source rock but also strong fracability of the shale oil reservoir. The excellent source-reservoir-caprock assemblage is also widely developed, which ensures good sealing ability and favors improving oil and gas recovery after fracturing. This study can theoretically improve the development efficiency of shale oil in the Ganchaigou area.
