Discussion on Helium Resource Accumulation Mechanism in Huagou Area of Jiyang Depression: Taking Well Hua 501 as an Example
-
摘要: 花沟地区为济阳坳陷富氦天然气资源的主要分布区,区内多口天然气井具有氦气异常显示,其中以花501井最为典型,氦气含量高达2.08%~3.08%。本次研究基于地质、地震、重力、航磁、测试等数据资料,以花501井为例,对研究区氦气来源、运移通道和圈闭条件进行了系统分析,提出研究区氦气成藏主要控制因素。研究认为,花沟地区氦气属于壳幔混合无机成因型,古近纪以来的火山-岩浆活动强烈,提供了充足的气源;花沟-高青断裂与研究区南部的深大断裂在深部连通,形成了氦气运移的主要通道;由于经历多期构造运动,发育多种类型的圈闭。据此推断,深部新生代岩浆活动活跃,与花沟-高青断裂相连通的相关系列圈闭发育区是研究区氦气成藏的有利目标区。Abstract: The Huagou area is the main distribution area for helium-rich natural gas resources in the Jiyang Depression. Many natural gas wells in the area show helium anomalies, among which Well Hua 501 is the most typical, with a helium content as high as 2.08%~3.08%. Based on geological, seismic, gravity, aeromagnetic, testing and other data, this study took Well Hua 501 as an example to systematically analyze the source of helium, migration channels and trap conditions in the study area. Tibetan main control factors. The study believes that:the helium gas in the Huagou area belongs to the mixed inorganic genesis type of crust and mantle, and the volcanic-magmatic activity since the Paleogene has been strong, providing sufficient gas sources; connected to form the main channel for helium migration; due to the multi-stage tectonic movement, various types of traps have developed. Based on this, it is inferred that the deep Cenozoic magmatic activity is active and the related series of trap development areas connected with the Huagou-gaoqing fault are favorable target areas for helium accumulation in the study area.
