双侧向测井是测井分析中的重要电法测井技术,为判断油水层提供有力的支持,随着勘探开发的不断深入,对薄层以及薄互层已经成为一种被开发的油气储集层,传统的双侧向仪器纵向分辨率已不能满足正确评价薄层以及薄互层的要求.本文在二维轴对称地层下,利用有限元方法编制了计算高分辨率双侧向测井仪器响应的数值模拟程序;利用有限元方法对高分辨率双侧向测井仪进行理论优化设计,提出了一种高分辨率双侧向电极环结构优化方案.经过优化后高分辨率双侧向在纵向分辨率达到0.2 m、探测深度达到1.03 m;对优化后高分辨率双侧向测井仪以及Cyber Service Unit(CSU)双侧向测井仪的井眼、探测深度、分层能力、以及薄互层影响进行对比分析,高分辨率双侧向受井眼影响较大,必须进行井眼校正;高分辨率双侧向的浅侧向CSU双侧向探测深度相同,但是深侧向略低于CSU深侧向;高分辨率双侧向在薄互层与薄层的响应要远优于CSU双侧向. Bilateral lateral logging is an important electrical logging technique in well log analysis. It provides strong support for the judgment of oil and water layers. With the deepening of exploration and development, thin and thin interbed has become a developed oil and gas Reservoirs, the traditional longitudinal resolution of dual lateral instruments can not meet the requirements of correct evaluation of thin and thin interbed.In this paper, under the two-dimensional axisymmetric stratum, the finite element method A numerical simulation program of well instrument response was proposed.An optimized scheme of high-resolution double-sided electrode ring structure was proposed using the finite element method for theoretical optimization design of high-resolution double-sided logging tool.After optimization, high resolution dual Lateral resolution of 0.2 m in the longitudinal direction, the detection depth of 1.03 m; on the optimized high-resolution dual lateral logging tool and Cyber ​​Service Unit (CSU) dual lateral logging tool borehole, depth of exploration, stratification Ability and thin interbedded layer, the high-resolution bi-lateral direction is greatly influenced by the wellbore and borehole correction must be performed; the high-resolution bi-lateral shallow lateral CSU has the same bilateral probing depth but the deep Slightly lower than CSU sideways Lateral; High Resolution Laterolog response in thin interbedded thin much better than the bilateral CSU.
