This, the quantitative description method of the casing resistivity logging material is given, and a set of software is used to describe the quantitative description of the casing resistivity. This paper analyzes the Russian geophysical exploration company "is a 31 - 7 well logging instrument to measure truth, elaborates the task process and instrument characteristics of Russian through casing resistivity logging, and analyzes the Russian through casing resistivity logging instrument and the Schlumberger Corp through casing resistivity logging instrument in measurement, instrument structure, influence of different identity etc.. According to different regions, different well conditions, different logging series gives 7 kinds of clay content and in fact set method, 4 kinds of porosity and in fact set; laminated shale and argillaceous sandstone evacuation parallel conductance based on the actual, and suspended in the electrolyte in the actual three-dimensional periodic conductive charged spheres, set up evacuation mud and layered at the same time the existence of mixed mud shaly sand double layer conductivity model analysis of the actual evacuation; clay cation exchange capacity, cementation exponent and saturation exponent change influence on mold; measurement data using 2 sets of evacuation shaly sand test measurement data and the 1 group with evacuation and laminated shale argillaceous sandstone natural hybrid samples to evaluate the mold practicality and versatility; take the dichotomy calculated water saturation of the mold. At the same time, Forward developed a platform that logging through casing resistivity logging software based on quantitative material, and use the software of Daqing Oilfield a la 9 inspection PS2604 five export of Russian through casing resistivity logging material to stop the disposal and, through specific analysis and evaluation results of notes, the Russian. Casing resistivity logging method can quantitatively explain the useful and in fact set water flooded layer flooding level, can change the reservoir monitoring situation of residual oil saturation, reservoir and accurately identify potential sites. 目录: 摘要 4-5 ABSTRACT 5 创新点摘要 6-9 前言 9-17 1 论文的探讨目的和意义 9-10 2 过套管电阻率测井解释措施的探讨近况 10-16 3 论文探讨的主要内容 16-17 第一章 过套管电阻率测井原理 17-24 1.1 过套管电阻率测井的一般原理 17-19 1.2 斯伦贝谢过套管电阻率测井原理 19-20 1.3 俄罗斯过套管电阻率测井原理 20-24 第二章 储层参数确定措施 24-33 2.1 地层泥质含量的确定措施 24-27 2.2 地层孔隙度的确定措施 27-29 2.2.1 地层总孔隙度的确定措施 27 2.2.2 地层有效孔隙度的确定措施 27-29 2.3 地层束缚水饱和度和渗透率的解释措施 29-30 2.4 层状泥质和分散泥质含量的确定措施 30-32 2.5 确定泥质电阻率、粘土电阻率、地层水电阻率 32-33 第三章 储层含水饱和度的确定措施 33-48 3.1 混合泥质砂岩双电层电导率模型的建立 33-39 3.1.1 泥质砂岩泥质导电机理探讨 33-36 3.1.2 混合泥质砂岩双电层电导率模型的推导 36-39 3.1.3 含水泥质地层电导率C_o 和地层水电导率C_w 的关系 39 3.2 混合泥质砂岩双电层电导率模型参数的确定 39-41 3.2.1 阳离子交换容量的确定 40 3.2.2 系数分量的确定 40 3.2.3 水界限校正系数的确定 40 3.2.4 确定地层因素、胶结指数和饱和度指数 40-41 3.3 混合泥质砂岩双电层电导率模型的作用因素略论 41-42 3.3.1 分散粘土阳离子交换容量对双层电导率模型的作用 41 3.3.2 胶结指数和饱和度指数变化对双层电导率模型的作用 41-42 3.4 混合泥质砂岩双电层电导率模型的精度略论 42-45 3.4.1 计算饱含水分散泥质砂岩岩样电导率与测量电导率的比较 42-43 3.4.2 计算含油分散泥质砂岩岩样电导率与测量电导率的比较 43-44 3.4.3 计算含油混合泥质砂岩人造岩样电导率与测量电导率的比较 44-45 3.5 混合泥质砂岩双电层电导率模型含水饱和度的求取措施 45-48 第四章 实际资料解释与运用 48-61 4.1 喇9-检PS2604 井实例略论与结果评价 48-51 4.2 北2-20 检丙279 井实例略论与结果评价 51-53 4.3 北1-21-551 井实例略论与结果评价 53-57 4.4 北1-30-564 井实例略论与结果评价 57-58 4.5 喇2-3312 井实例略论与结果评价 58-61 结论 61-62 参考文献 62-67 文章目录 67-68 致谢 68-69 详细摘要 69-77 |
