针对新疆准噶尔盆地西北缘石炭系地震反射杂乱，采用地震手段进行内幕构造解剖难度大的问题，开展了基于成像测井解释的石炭系火山岩内幕构造解剖研究。以盆地西北缘克拉玛依油田三区石炭系油藏为例，采用成像测井资料识别地层产状、单井成像测井构造解释及多井地层产状组合断层解释等，对该区石炭系火山岩地层内幕构造进行解剖，识别出石炭系内部2条逆断层。部署检查井证实解释的合理性，验证了成像测井解剖复杂火山岩内幕构造方法的适用性，为准噶尔盆地西北缘火山岩复杂地层构造解剖及油藏优化部署提供新的方法。

The carboniferous structure is very complicated in the northwest of Junggar basin. It makes the research on the structure in this area difficult by the seismic and diplog interpretation for its diverse lithology and well-developed fracture. For those reason, the seismic and diplog data quality is poor. The downhole true formation occurrence can be provided directly with imaging logging. Furthermore, the structure shapes can be finely interpreted with logging data. The paper aimed at dividing the lithological layer of the volcanic layers and interpreting the true formation occurrence by the imaging characteristics. Finally, the structure of volcanic is dissected according to the regular pattern of multi-well stratigraphic occurrence, founding that there are two reverse faults in this complex steep structures area.The result shows that the new method of the interpreting of structure of volcanic reservoir is effective.
