摘　　要：喇萨杏油田进入高含水后期开采阶段后,调整挖潜的难度越来越大,应用测井资料对于评价薄差层、非均质层水淹状况存在着一定的难度,迫切需要寻找一种提高油层水淹状况解释准确度的新途径。该文在系统总结密闭取心样品的气相色谱谱图的规律基础上,探索了应用气相色谱资料对油层水淹级别定性评价的新方法,取得了一定的效果,展示了该项技术在综合判断油层水淹程度、提高老油田调整挖潜效率方面良好的应用前景。With entering high water cut stage of La-Sa-Xing Oilfields, it is difficult to adjust and taping potential. Using logging data to evaluate thin and poor reservoirs and watered out status of heterogeneous layers is a challenge. This paper summarizes the rules of gas chromatogram of sealed coring sample, and discusses a new method for quantitatively evaluate the grades of watered out layers using gas chromatographic data. It shows the potential of this technique in comprehensively determining watered out degree of reservoirs and improving potential tapping efficiency of mature oilfields.
