惠民凹陷孔二段烃源岩综合评价

Comprehensive evaluation of source rock in Kong 2 formation of Huimin depression

从惠民凹陷盘深 3井有机碳、饱和烃气相色谱分析等多种化验分析资料出发 ,对孔二段地层暗色泥岩有机质进行系统评价。评价结果认为 ,该井孔二段地层暗色泥岩有机质丰度低 ,干酪根类型差 ,有机质成熟度过高 ,不具备生成工业油气的条件。文章还结合区域地层分布特征 ,指出下一步寻找深层烃源岩的方向。

Based on many analytical data such as organic carbon and gas chromatography of saturated hydrocarbon of well Panshen3 in Huimin depression, organic matters in dark shale of Kong 2 formation has been evaluated systematically. The result of evaluation is that, in this well, the abundance of organic matter is low in Kong 2 dark shale, the kerogen is poor, the maturity of organic matter is too high, and the condition for commercial oil and gas is insufficient. Combining with regional distribution of formation, the direction for finding deep source rock is pointed out.
