摘要
目的确定苏里格气田东区低阻气层的成因机理,指导测井气层识别。方法以岩心分析资料和测井资料为基础,从毛细管理论入手,进行综合研究。结果孔隙结构是影响低阻气层成因的主要因素。结论 "双高(高孔隙度、高微孔率)、双组(渗流孔隙、微孔隙)"孔隙结构特点是低阻气层形成的主要原因。
Aim der to guide log To confirm the causing mechanism of low resistivity gas zone in the East of Sulige Gaslield, in orinterpretation. Methods On th basis of well logging response and core analysis information, the capillary theory, muhidisciplinary analysis are applied. Results The pore structure is the main influencing factor causing the low resistivity gas zone. Conclusion High porosity, high microporosity and the coexisting of filtrational pore and micropore are the main reason which induce the low resistivity gas reservoir.
