【摘要】：随着油气资源勘探及开发难度加大,由陆相、高孔渗、均质、浅层逐渐过渡到海相、低孔渗、非常规、深层油气资源,其"复杂非均质"特性使得对地层流体特别是地层水及其导电特性评价尤为关键.利用试井分析数据可获得精确的地层水矿化度信息,但试井数据有限,不能获得每个储层的地层水矿化度及电阻率信息,且试井分析成本高、时间长,而测井曲线通过一定的理论计算公式能够提供地层水电阻率信息.在地层水特性分析的基础上,根据地层水电阻率评价技术研究进展,本文将其分为三种主要计算类型:水样分析评价方法、常规测井评价方法和成像及核磁测井评价方法,总结和讨论不同测井评价地层水电阻率的方法原理,并阐述其应用过程中的优势和不足,同时对地层水电阻率测井仪器国内外进展现状进行阐述.
[Abstract]:As the exploration and development of oil and gas resources become more difficult, from continental facies, high porosity and permeability, homogeneity, shallow layer to marine facies, low porosity and permeability, unconventional, deep oil and gas resources, Because of its complex heterogeneity, the evaluation of formation fluid, especially formation water, and its conductivity is very important. Accurate formation water salinity information can be obtained by using well test analysis data, but the well test data is limited, and the formation water salinity and resistivity information of each reservoir can not be obtained, and the well test analysis cost is high and the time is long. The logging curve can provide formation water resistivity information through a certain theoretical formula. Based on the analysis of formation water characteristics, according to the research progress of formation water resistivity evaluation technology, this paper divides it into three main calculation types: water sample analysis and evaluation method, conventional logging evaluation method, imaging and nuclear magnetic field logging evaluation method. This paper summarizes and discusses the methods and principles of different logging methods for evaluating formation water resistivity, and expounds the advantages and disadvantages in its application. At the same time, the present situation of formation water resistivity logging tools at home and abroad is expounded.
