火山岩油气藏是近年来吐哈油田热点勘探领域,已相继在不同层系的火山岩储层中取得了突破.而火山岩储层岩性复杂多变,其岩性的影响远远超过流体的影响,因此岩性识别对该地区显得尤为重要.准确确定火山岩岩性是火山岩岩性储层精细评价的基础,也是测井评价的主要难点.文中以三塘湖盆地马朗凹陷石炭系卡拉岗组火山岩岩石薄片资料为基础,研究出了利用常规测井信息识别矿物成分,应用成像测井信息识别火山岩的岩石结构及构造,并将两者结合对火山岩岩性进行综合判别的适合吐哈油田火山岩岩性识别方法.该方法对马朗凹陷火山岩岩性识别具有较好的应用效果.

In recent years, volcanic rock reservoir exploration has become a hot spot in Turpan-Hami Oilfield, and breakthrough has been made in different strata of volcanic rock reservoir. The reservoirs have been affected more greatly by its complex and variable lithology than the fluid, so lithology recognition is particularly important in the area.Accurate description of the lithology of volcanic rocks is the basis for precise reservoir evaluation of such type and is the major problem for logging evaluation. In this paper, a new technique is developed based on volcanic rock slices data of Kalagang Formation of Malang Depression in Santanghu Basin. It uses conventional logging information to identify the mineral composition, and applies imaging logging information to identify the volcanic rocks and tectonic structure, and finally integrates them into volcanic rock lithology comprehensive identification, which is suited for the Turpan-Hami Oilfield. The method has got good application effect in the lighology identification in Malang Depression.
