【摘要】 分析XF山西侧地区的深部构造特征、电性层与断裂的展布及圈定有利油气构造带,为含油气远景评价和选择有利区块提供依据,综合MT电法、重力和磁法资料,并以物性资料为基础,石油地质理论为依据,提出综合物探资料在XF山西侧油气地质—地球物理解释中的综合解释方法.通过对重磁电资料与石油地质资料的联合正反演综合解释,分析剖面中生界和古生界地层垂向分布,确定研究区电性层的展布、断裂及下组合有利生储盖组合的综合物探异常特征.结果表明:物探剖面中、东段最多发育3套电性层,西段可完整发育5套电性层,震旦系—寒武系地层发育厚度较大,构造变形相对较弱,是油气勘探的有利区,从而验证地球物理综合解释方法在XF山西侧地区的有效性.更多还原

【Abstract】 In order to understand the deep structure characteristics,electrical layer,fracture distribution as well as the delineation of favorable petroleum zone of the west side of XF Mountain,this paper proposed technical route of using integrated geophysical data in the geophysical interpretation of the gas geology on the west side of the XF mountain by using MT information,gravity data,magnetic data and physical property data guided by the petroleum geology.Based on the comprehensive interpretation of the forward calculation and inversion of the gravity,magnetic,electrical data,and the petroleum geological data,this paper carried out the in-depth study of the profile’s Mesozoic and Paleozoic strata vertical distribution and determined the spread of the electrical layer,fracture and geophysical abnormal characteristics of the under combination’s favorable combination of reservoir.The results indicated that the middle and eastern section of the profile developed up to three sets of electrical layer,while the western section can develop five sets of electrical layer completely,Ediacaran and Cambrian strata with thick tectonic and deformation is relatively weak,which is the favorable area for oil and gas exploration.These results verified the validity of the comprehensive interpretation methods in this area.更多还原
