摘要
本文针对油田地表下伏地层岩性的非均质性、地表士壤的粘土、沙土的吸附差异所造成的干扰,提出一种吸附丝通过色-质分析后,再经过数据处理获得的指纹解释方法。该方法在江苏 XNZ 已知油田的化探解释和辽宁宋家地区的油田预测应用中,取得了很好的效果,对于确定油田范围、选择井位、提高钻井的成功率,具有一定的现实意义。
Based on the better cumulative effects,large volume of information and multiple in- dices in the application of the adsorption technique,this paper suggests a method of in- terpretation—“fingerprint”method,which is obtained by a processing of GC-MS data of the gas from the adsorption filament,to eliminate the interference from the differential adsorption of the clay and sandy clay in the surface'soil. This method has been approved to be effective in oil and gas geochemical explo- ration,such as explaining some known oil fields in Jiangsu and forecasting unknown oil fields in the Songjia area,Liaoning province.There are some significanees in determining the extent of an oil field,pinpointing well location,as well as enhancing probabilities of success in exploratory drilling.
