综合利用测井资料评价油气层--以克拉玛依石南油田为例

在论述测井方法和适用条件的基础上，结合石南21井区头屯河组油藏地质特征，探讨了如何利用测井资料识别和定量评价油气层的方法。通过对阵列感应测井的应用效果分析，特别是结合泥浆滤液侵入分析，研究油、水层的测井响应特征，提出了利用测井资料快速、直观判断油层的方法；应用“岩心刻度测井”方法，采用统计分析技术，建立的油层定量评价模型在油藏精细评价和开发井测井解释中得到了应用，提供了精确的油层参数；在油藏的油水分布研究中，通过多口井的地层压力测试（MDT）资料，建立油藏压力剖面及确定储集层中流体密度参数，结合常规测井和试油资料等综合分析，准确地确定了油藏的油水界面。

Composite Application of Well Log Data to Evaluation of Oil-Gas Zones--An example of Shinan field, Karamay oilfield

Well logging methods and applied conditions are presented. Combined with the geologic feature of Toutunhe reservoir in Shinan-21 Well Block, the method for identifying and quantitatively evaluating oil-gas zone by using well log data is approached. The analysis of applied response from array induction log and the analysis of filtrate-invaded zone are conducted to study the log response features of oil and water layers, by which a quick and visual distinguishing method for distinguishing pay zone by means of well log data is proposed, The core-calibrated log approach and the statistical analysis technique are adopted to realize the application of developed quantitative reservoir evaluation model to detailed reservoir evaluation and well log interpretation and offer more proper parameters. For the study of oil-water distribution, the multi-well MDT data are used to build up the reservoir pressure profile and determine the fluid density of the reservoir. By the composite analysis of available conventional well log and production test data, the oil-water contact of this reservoir is exactly determined.
