| 中文摘要:干热岩资源是一种储量巨大的可再生清洁能源,干热岩的开发需通过深井将高压水注入深部岩层,使其渗透进入岩层的缝隙并吸收地热能量。裂隙网络作为流体的运移通道,在干热岩热能的开采与利用方面至关重要,储层裂隙因其分布的高度非均质性、控制和影响因素的多样性等,研究工作存在难点。本文从干热岩物探、钻井、综合测井等方面,系统总结分析储层裂隙准确识别的关键技术,对提高干热岩热能的开采和利用具有指导意义。 |

| Abstract:Hot dry rock resource is a kind of renewable clean energy with huge reserves, the development of hot dry rock needs to inject high-pressure water into deep strata through deep wells, make it penetrate into the crack of rock stratum and absorb geothermal energy. As the migration channel of fluid, fracture network is very important in the exploitation and utilization of thermal energy in hot dry rock, because of the high heterogeneity of reservoir fracture distribution, the diversity of control and influence factors, the research work is difficult. This paper systematically summarizes and analyzes the key technologies for accurate identification of reservoir fractures from the aspects of geophysical exploration, drilling and comprehensive logging of dry and hot rocks, which has guiding significance for improving the exploitation and utilization of thermal energy in hot dry rocks. |
