摘要：

焉耆盆地油田水有CaCl2和NaHCO3两种类型,矿化度为5.5～73.2g/L,呈正向水化学剖面特征,具明显的分区性:CaCl2型主要分布于宝浪苏木构造带的宝北区块的北部地区;NaHCO3型则主要分布在宝南、本布图、种马场区块及宝中区块的部分地区。油田水中有机质丰度均较低,多数在2×10-6以下;有机酸含量很高,一般为2546×10-6～5148×10-6;酚含量一般为0.12×10-6～4.63×10-6。已证实盆地存在自由交替带、缓慢交替带、阻滞带3个水文地质带,北部保存条件好于南部,中部好于盆地边缘。

Abstract:

There are two kinds of oil field water(CaCl2 and NaHCO3) in Yanqi basin, the water mineralization is 5.5～73.2/1,presenting in forward water chemical section character with apparent zoning. CaCl2 type is mainly distributed in northern area of Baobei block,in Baolang Sumu structural belt, whereas NaHCO3 is chiefly distributed in the blocks of Baonan,Benbutu,Zhongmachang as well as some areas of Baozhong block. Organic mater abundance in oil field water is lower(below 2×10-6) while organic acid content is very high(2546×10-6～5148×10-6 and acid content is usually 0.12×10-6～4.63×10-6. Therefore, it is confirmed that there are three hydro-geologic belts in the basin namely; free alternative belt, slow alternative belt and hindered belt, and the preserving condition in the north is better than that in the south and central part is better than that in the edge of the basin.

Key words: oil field water, geochemistry, oil-gas pool, zoning, Yanqi basin
