准噶尔盆地中拐凸起二叠系佳木河组砂砾岩沸石胶结特征及其成岩机制分析
An analysis of the zeolite cement in sand-conglomerate and the diagenetic mechanism of Jiamuhe Formation, Zhongguai area, Junggar Basin
摘要
Abstract
Zeolite cementation is extensively developed in sand-conglomerate of Jiamuhe Formation in Zhongguai bulge,Junggar Basin.The analysis of cement characteristics and diagenesis of zeolite is of great importance for genetic mechanism exploration of the reservoir.Based on core and microscope observation,in combination with geochemical test methods such as electronic microprobe analysis,the authors studied the lithologic features,cementation and dissolution characteristics of Jiamuhe Formation.The results show that the sand-conglomerate of Jiamuhe Formation has developed zeolite,analcite,laumontite,and heulandite.There is no obvious cement zonality between different types of zeolite.Meanwhile the sand-conglomerate is often cemented by multi-period and multi-type zeolite,it is concluded that these cement characteristics had an inseparable relationship with diagenetic environment.It was a comprehensive response result of different stages of diagenetic environment on the basis of a transient openness alkaline diagenetic environment of the early stage,assisted by several alternations between acid-base diagenetic environments of the middle stage,and dominated by a long-term closed alkaline diagenetic environment of the late stage.关键词
