关于拓展地化录井应用范围的思考

Thought about expanding geochemical logging application scope

针对因钻井新工艺的应用给岩屑录井带来的影响,以及由此而导致的地化录井难以获取真正代表所钻地层的岩样问题,该文依据多年地化录井数据分析研究及实践经验,探讨了地化录井对未钻油气层预测、混油钻井液条件下的真假油气显示识别、老井复查工作中的油气层评价和原油性质判断四个方面的方法和作用。这对拓展地化录井应用范围、提升应用水平和加大研究力度具有一定的促进作用。

The application of new drilling technology has brought about much influence on cutting logging, therefore resulting in getting the real cuttings representing the formation with difficulty. Based on the geochemical logging data analysis research and the practical experience of many years, geochemical logging methods and functions were discussed from the aspects of prediction of the undrilled hydrocarbon reservoir, true or false oil and gas shows′ identification under the condition of oil emulsion drilling fluid, hydrocarbon reservoir′s evaluation and crude oil property′s diagnoses during the oil well checking.This exposition has brought about a certain acceleration in expanding geochemical logging application range, increasing the application level and strengthening research dynamics.[WTHZ]
