摘要
轻烃是判断地下含油气的良好指标。在东濮凹陷应用罐装岩屑轻烃录井,由于色谱分析方法和技术上的改进,确定在常温下一次进样,分离出 C_1—C_(13)烃类。通过烃类相对(%)和绝对(ppm)含量及地球化学指标的计算,找到了具有开采价值的产层,评价了油气层质量。对轻烃的分布和演化规律有了新的认识。
Light hydrocarbons is a good parameter to identify underground oil and gas,light hydrocarbon logging of the canned drilling cuttings is applied in Dongpu depression.Because of the improvement on chromatographic analy- sis method and technology,hydrocarbon C_1-C_(13)can be seperated for one -step-introduced sample under normal temperature to calculate of the relative concentration(in%)and absolute concentration(in ppm)as well as some geo- chemical parameters,commercial reservoirs have been found and their qu- alities evaluated.Further more a new understanding of light hydrocarbon dis- tribution and evolution has been abtained. The light hydrocarbon logging of the canned drilling cuttings will become an effective tool for hydrocarbon exploration.
