摘要： 火山岩作为油气储集层己在新疆北疆地区石炭系油气勘探中获得证实。通过对准噶尔盆地陆东地区实例揭示的火山岩物性特征、提取的重磁电异常信息和识别的火山岩岩性研究表明,必需使用1：50 000 高精度重、磁、电综合勘探资料及相应的特殊处理方法;利用高精度重磁力、建场测深资料可以有效识别具有密度、磁性、电阻率差异的火山岩岩性区带的分布;陆东地区实钻石炭系岩性与重磁电预测结果具有较好的吻合性。

Abstract: Volcanic rocks as an oil-gas reservoir has been approved for the Carboniferous petroleum exploration in the northern Xinjiang. The exploration of eastern Luliang area in Junggar basin reveals that the petrophysical property, the gravitational-magnetic-electric abnormal information and the lithology identification of its volcanic rocks. The study shows that the high- precise gravitational-magnetic-electric data in scale of 1∶50 000 and corresponding special processing methodologies should be applied to identify the regional distribution of the volcanic lithology with density, magnetism and resistivity differences. And the predicted results are more accordant with the real Carboniferous lithology from drilling in this area.

Key words: Junggar basin, gravitational prospecting, magnetic prospecting, electric prospecting, abnormal pattern, Carboniferous, volcanic rock
