潍北凹陷页岩气资源潜力分析

Potential Analysis on Shale and Gas Resources in Northern Weifang Depression

摘要:

页岩气作为一种非常规能源，在北美已经取得了相对较成熟的勘探开发经验，潍北凹陷沉积了较厚的暗色泥页岩，为摸清页岩气"家底"，笔者通过分析潍北凹陷央5井、昌64井等一系列钻井取芯测试结果，对潍北凹陷孔店组二段地层暗色泥页岩厚度、有机质类型、丰度、成熟度等页岩气形成条件进行了系统研究，结果表明，潍北凹陷孔二段泥页岩形成于浅湖相深湖相环境，暗色泥页岩厚度较大，有机质含量、成熟度均较高，且埋藏较浅，具备页岩气形成条件，是省内页岩气勘探的有利目标层位。

Abstract:

Through analysis on formation conditions of dark shale thickness, organic matter type, abundance and maturity of shale and gas in the second section of Kongdian formation in Weibei depression, it is showed that shale in the second Kongdian formation in Weibei depression was formed in the shallow lacustrine facies deep lacustrine environment. The thickness of dark shale is large, organic matter content and maturity are high, and buried in shallow part. It has shale and gas formation conditions and is favourable for the formation of shale gas exploration in the Shandong province.
