油田水是一个复杂的化学体系,它与地层深部油气藏存在许多相关的信息。油田水分类作为油田水地球化学的一个重要命题,它不仅是个理论问题,而且是个找油的实际问题。已经有过很多研究,其中苏林分类法有较广的影响。苏林认为:CaCl_2和 NaHCO_3型水是油田水型。稍后的舍尔勒分类,考虑了水中阴阳离子的排列顺序以及硫酸盐的饱和程度。这些分类系统对于我国的一些油田 Oilfield water is a complex chemical system that has much to do with the deep reservoir in the formation. As an important proposition of hydrogeochemistry in oilfields, oilfield water classification is not only a theoretical issue, but also a practical issue of finding oil. There have been many studies, of which the Surin taxonomy has a broader impact. Surin that: CaCl_2 and NaHCO_3 type of water is oilfield water. Later Scheler classification, taking into account the order of the anions and cations in the water and sulfate saturation. These classification systems for some of our oil fields
