【摘要】 以岩石物性、重磁电震、钻井等资料为基础,根据研究区具体地质情况,提出火山岩分布预测、火山岩岩性预测、有利区带及目标评价的重磁电震配套技术。通过在陆东—五彩湾地区的综合应用,完善了现有的方法技术,形成了有效的重磁电震综合勘探技术流程。对陆东—五彩湾地区火山岩气藏分布规律进行了分析总结,提出了该区火山岩气藏勘探的重要认识:磁力异常梯度带是火山岩断裂带,断裂控制了火山岩的分布,也控制了火山岩的局部构造;磁力异常梯度带是火山岩裂缝发育带,是火山岩储集层发育的有利部位;近烃源岩磁力异常梯度带是火山岩油气藏的富集区带。预测的有利区块(区带)、有利目标得到了钻探证实,表明了本研究方法正确有效。图14表1参13更多还原

【Abstract】 Based on petrophysical,magnetic,gravity,electric,seismic and drilling data,combined with geological regularities,this paper proposed an integrated approach for the distribution prediction and lithology recognition of volcanic rocks,as well as the exploration prospect and target optimization of hydrocarbon deposits.The exploration technology was improved in the application to exploration in the Ludong-Wucaiwan area in Junggar Basin.Some important viewpoints are concluded as follows: aeromagnetic abnormal gradient belts correspond to volcanic faults,faults control the distribution of volcanic rocks and accordingly their local structures,aeromagnetic abnormal gradient belts correspond to highly-developed fracture zones and are prospective areas for volcanic reservoirs.The proposed integrated approach is proven effective by the exploration drilling results with high-flow gas wells.更多还原
