阿萨姆盆地是印度的主要产油区之一,它几乎占了印度石油产量的一半。现在,这个地区已建成了六个油田(见图1)。该地区主要的含油砂岩是渐新统的巴赖尔组和中新统的提帕姆组。所产原油属重质油并以高蜡为特徵,含蜡量高达10—15％,其中正烷烃范围为C_(22)—C_(36)(表1)。不论在垂向上还是横向上,含蜡量的变化范围都较宽。 这些原油的生油层被认为是布赖尔组而不是提帕 Assam Basin is one of India’s major oil-producing regions, accounting for almost half of India’s oil production. Six fields have now been built in the area (see Figure 1). The main oil-bearing sandstones in the area are the Oligocene Group of the Barrers and the Miocene Teppam. Crude oil produced is a heavy oil characterized by high wax content, with wax content as high as 10-15%, of which n-alkane range C_ (22) -C_ (36) (Table 1). Whether in the vertical or horizontal, wax content of the wide range of changes. The crude oil formations are considered to be the Brigade rather than the Tippa
