库车前陆盆地是塔里木油田天然气的主要富集区,目前在该区相继发现了克拉2、吐孜洛克和迪那2等一批特大型和大型气田,但由于该区属典型的前陆逆冲断裂带,构造作用的影响十分强烈,岩石的成分成熟度和结构成熟度均较低,储层岩性杂乱、物性差、孔隙度小、渗透率低,地层纵向上具有砂泥岩薄互层,地层压力系数变化大,钻井泥浆侵入严重。所有这些不利因素使得常规测井方法对气藏的评价精度较低。为了提高测井效果,近年来塔里木油田陆续引进了斯仑贝谢、阿特拉斯以及哈里伯顿等成像测井技术,这些新技术在克服上述不利因素、解决泥浆侵入、判断气水界面、识别流体性质和精确计算饱和度等方面均具有常规测井技术无法比拟的优点。测井新技术在库车前陆盆地气藏描述中的应用,有效地提高了测井方法对气藏的评价精度。

The Kuche foreland basin is an gas area of enrichment. By new, there have been found several large-scale gas fields, such as Kela 2, Dina 2 gas fields. The compositional and texture maturities of rocks are very low because of intensely tectonic movement and adjacent material resource. The reservoir is belong to low porosity and permeability with lithological mixture and sand-shale thin inter layers, add it, the area’s strata pressure coefficient variety big, mud invade serious.
