    摘要: 水体断层破碎带严重影响着水体下资源开采安全,因此对水体断面的地质调查是资源勘探技术中最基础的过程。通过水底断面的地质调查,能够更好地对油气储层开采中可能遇到的地质灾害进行评估,预测可能危及钻井安全的地质因素。高密度电阻率法具有智能化、分辨率高以及一次布设、效率高等特点,与传统电阻率法相比勘探能力显著提高。本文将高密度数值分析的方法应用于油气储层地质中水体断层调查,通过查明水体断面勘探线上河床及两岸基岩起伏形态及风化层度,分析了电法工作在油气储层地质中的干扰类型和干扰来源,重点对高密度方法所采得数据采用数值计算处理。研究结果表明,高密度数值分析方法能够有效摸清水体断面的工程地质概况,对于水体下资源开采中可能遇到的地质灾害开展了深入分析,具有重要的应用价值。 Water fault fractured zone is significant to the resources mining safety under water, and the geo-logical survey of water section is the basic process of resources exploration technology. It can evaluate the potential geological disaster in the hydrocarbon reservoirs mining and forecast the geological factors that endanger the drilling safety by the means of geological survey of water sec-tion. Meanwhile, compared with the traditional resistivity method, high density resistivity method with the characteristics of intellectualization, high resolution, one-time layout and high efficiency, significantly increases the exploration capability. This paper applied the high density numerical analysis method in the geological survey of hydrocarbon reservoirs water section, by ascertaining the fluctuating form of bedrock and the degree of weathered layer, analyzed the interfere type and source of resistivity method in the hydrocarbon reservoirs, and focused on the numerical analysis in the data processing. The results showed that the high density numerical analysis method can effectively ascertain the geological situation of hydrocarbon reservoirs water section. Then, the potential geological disaster in the resources exploration process was analyzed and the applicability of this method was proved.
