摘要

盆地流體是沉積盆地中非常活躍的因子，盆地流體的水文地球化學特徵主要是受控於油、氣、水、岩的相互作用。油氣田水的來源及成因是非常複雜的，因此結合水同位素、主要離子、微量元素及放射性同位素綜合分析來解釋油氣田水的成因與來源是必要的方法。本文闡述如何利用其相互間的地球化學特性追蹤油氣移棲的路徑、判別沉積環境、進行區域地層對比及利用區帶水動力作用尋找可供鑽探的有利區域。

The basin fluid is the very active factor in the sedimentary basins, the hydrogeochemistry is mainly controlled by fluid- rock interaction. The source and genesis of the formation water are very complex. It is necessary to combine the water isotopic components, major ions, trace elements and radionuclides to explain the genesis and source of the formation water. This study described applying interrelationship of geochemistry characters to research the formation water, in order to trace fluid flow direction, discriminate the sedimentary environment, carry out the regional stratigraphic correlation, and use the hydrodynamic effect to find the favorable area for drilling.
