摘要： 准噶尔盆地低阻油气层成因类型多、分布区域广、识别难度大, 通过对其特征分析, 对低阻油气层的成因进行了探讨, 提出相应的识别方法。低阻油气层表现为低电阻、砂泥岩互层、微孔隙发育、粘土矿物类型主要为蒙脱石和伊/蒙混层、钻井显示较弱。伊/蒙混层强附加导电性、高矿化度、高饱和度束缚水、钻井泥浆侵入等是形成低阻油气层的重要因素。目前主要通过测井、录井等技术进行低阻油气层的识别。

Abstract: Low-resistivity layer (reservoir)in Junggar basin features multi-origin, wide distribution and difficult identification. This paper discusses its origin and presents the identifying method. Study shows that low-resistivity layer is characterized by low resistivity, sand-mud interbedding, developed micropore and weak drill show, with montmorillonite and illite-smectite interstratified minerals. And additional conduction, high salinity, high irreducible water saturation and drilling mud invasion, etc. are the key factors for forming low-resistivity layer (reservoir). Well log and logging, etc. are the main identifying techniques for it.

Key words: Junggar basin, low-resistivity layer (reservoir), origin, identifying method
