摘要: 精选并研究了准噶尔盆地252个活化水样,发现矿化度大、活化系数高、处于活化早期状态的NaHCO3水分布在克拉玛依油田九区—乌尔禾油田—风城油田—玛湖油田一带,同时地层水中微量元素硼(B)、铵($NH_4^+$)、有机氮的含量呈现异常高值分布。这一带正是准噶尔盆地主要的“地幔上涌区”和大断裂通过区。盆地东部另一“地幔上涌区”的五彩湾油区一带,也有较多活化水出现。过去评价地下环境的封闭性只靠CaCl2型水的“变质系数(rNa/rCl)”,现在对NaHCO3型水所在的环境也可评价其封闭性;有活化水的存在,可望找到油气藏;并可以推测有否轻质油藏、判断油气藏的相对形成期。

Abstract: 252 activated water samples have been picked and analyzed. It is found that they are characterized by high salinity, high acti-vated coefficient,and NaHCO3 formation water in early state of activation is mainly distributed along District 9 of Karamay oilfield-Wuerhe oilfield-Fengcheng oilfield-Mahu oilfield, with trace elements of boron (B), ammonium (NH4+), and abnormal high content of organic carbons. This area is just situated in zones where mantle is bulging and a great fault goes through in Junggar basin. In eastern part of the basin, there also exists a Tantle bulge zone”called W ucaiwan oil region in which much activated water occur. In the past, to evaluate subsurface occlu-sion property only depended upon the ratio of rNa/rCl of CaCl2 formation water. Nowadays, we can even evaluate the subsurface occlusion property of NaHCO3 water. Appearance of activated water implies the hopes for finding out hydrocarbon reservoirs, presuming if a light oil pool is found, and estimating the possibly formed period of a hydrocarbon reservoir.

Key words: Junggar basin, formation water, NaHCO3 water type, CO2, activation, boron (B), ammonium (NH4+)
