| 摘 要： | 气测录井资料是在油田的各个阶段均要测量的基础资料,对气测录井资料进行定性分析,结合测井资料进行油、气、水层判别,是测井解释常用的一种方法。如何对气测资料进行定量分析,提高气测资料在疑难层评价方面的应用,是目前需要努力的一个方向。在分析总结了气测全烃曲线的形态特征及所对应的储层含油气性质基础上,将三角形图解法与气测全烃值相结合综合识别低阻油层等疑难储层,取得了较好的应用效果。该方法在渤海油田资料录取较少的开发井测井解释中具有较好的应用前景。

| Abstract: | As basic data for gas logging,log data are necessary in each stage of oilfield.Combined with well-log data,qualitative analysis of log data is a common method for logging interpretation,which is used for oil-gas-water identification.At present,how to carry out quantitative analysis and conduct uncertain layer evaluation of gas logging data should be focused on.In this paper,based on the characteristics of total hydrocarbon gas logging curve and oil-bearing properties of corresponding reservoirs,in combination with Triangualr daigram method and total hydrocarbon gas logging values,good application effects have been realized on uncertain layers indentification such as low resistivity oil layers.The method is of great application prospect for logging interpretation of development wells with less logging data. |
