摘要
流体性质识别是测井解释中一项非常重要的工作,利用交会图技术识别储层流体性质是一种简单而有效的方法,具有简单、直观的特点,且针对性很强。在识别流体性质的日常工作中,根据测井曲线或解释出参数再对比图版,不仅速度慢,出错率较高而且也不能直观显示结果。特别是在某些储层参数处于临界值时,就更难判断了。根据工区地质和测井资料建立交会图版,并从中优选界限明显、效果较好的交会图,将其组合来判断流体性质。并利用Excel VBA编译的优快判别程序将待判别层的储层参数值自动的一次性投影到所有识别图版中,根据该层在所有图版中所处的区域并综合比对各个参数值的判别标准,便可快速直观地判别出流体性质。利用VBA编译的程序,简便实用,并以计算机自动直观显示代替了人工识别,提高了工作效率和判别的准确性,达到准确、快速、直观地识别储层流体性质的目的,并取得了较好的应用效果。
Fluid property identification is very important in logging data interpretation. Crossplot technique is g simple and effec- tive method to identify reservoir fluid property, with advantages of simplicity and visuality. In daily work, it is very slow to compare crossplots on the basis of logging curve or interpreted parameters, and lots of mistakes occur and the results can not be visually display. Especially when some parameters are at critical value, it is more difficult to identify the fluid properties. In this paper, some cross plots were mapped on the basis of the geological and logging data, the fine ones with clearer boundaries and better effects are selected to identify fluid property. With program compiled in Excel VBA, the reservoir parameters of target layer can be automatical- ly projected on all of the selected cross plots once. Fluid property can be identified quickly and accurately according to the position of the projections on the cross plots and by comprehensively contrasting with the criteria of the parameters. The simple and useful pro- gram compiled in VBA can improve our work efficiency and accuracy by displaying results automatically and intuitively rather than artificial cognit!on. The program has be used to identify fluid property accurately, quickly and intuitively, and good application results have been obtained.
