通过对页岩油气领域所面临的关键难题的梳理和分析,提出要认识页岩油气的成藏机理、指导甜点区的选定及有效开发需要首先认识以下三方面的关键科学问题(1,2,3)和两方面的关键技术问题(4,5)：1)致密油气的可流动性及其表征,2)致密岩石的成储机理,3)致密油气的赋存机理和赋存状态,4)致密岩石无机非均质性的评价和预测,5)致密岩石有机非均质性的评价和预测。初步的探究表明,在纳米材料固-流吸附剂定量表征
The solid inner core of the Earth consists of heavy minerals Fe and Ni with a fraction of light elements such as O,S,Si.During the inner core formation,these light elements escape and rise up through
The Tianshan orogenic belt is one of the youngest and highest inland orogenic belts in the world.In order to investigate the detailed structure of the crust and uppermost mantle of the eastern Tiansha
Combining the newly collected teleseismic body waves recorded by Cuoqin-Dangxiong passive seismic array of 59 broadband stations with waveforms from several previous temporary local seismic arrays of
Anthropogenic activities like oil and gas production or geothermal field exploitation are known to induce small magnitude earthquakes (usually M5.5) on nearby active tectonic faults3,4 – which has bee
On account of increasingly frequent rock burst hazards at present,the theoretical basis of rock burst determination through P-wave velocity was analyzed based on the experiment relation model of stres
Knowledge of hidden structure defaults,stress redistribution and rock burst hazard around the longwall mining panel will allow for greater extraction efficiency with reduced safety concerns.In this pa
The rockburst phenomenon caused mostly by mining-induced tremors becomes progressively more severe as the mining depth and extent increase.Microseismic monitoring technique,as the major investigation
对南北地震带地区发生的强震进行了系统的回溯性震例研究，并利用“区域技能评分”方法对预测结果进行了效能评估。结果表明，地震“丛集率”方法对南北地震带地区6.5级以上具有较高的预测效能。当变换预测的目标地震震级，统计检验结果显示，对南北地震带地区，最佳预测的目标地震震级为6.5级。进一步考察地震“丛集率”方法的最佳预测时间尺度，对南北地震带地区系统的回溯性研究和利用“区域技能评分”方法检验结果表明，最
本文通过基于遥感影像解译，通过对龙门山中段盆山分界地带的构造地貌详细调查，发现沿断层表现为山前线性洪积台地的前缘陡坎，通过探槽发现断层表现为逆断，断错了晚第四纪地层的证据;断错地貌的RTK测量表明山前洪积台地陡坎高10.2±1.4m，年代测试结果表明山前洪积台地的年龄为-28ka，从而表明龙门山中段山前断裂的晚第四纪垂直滑动速率0.36±O.O5mm/a。布设的浅层地震勘探与收集到的石油勘探资料也
