摘　　要：受特殊地质结构的影响,碳酸盐岩测试出水情况十分复杂。根据出水状况及其地球化学特征,将测试水划分为7种类型。以塔里木盆地轮南奥陶系碳酸盐岩古潜山油气藏为例,根据测试水的地球化学特征,参考地层水标准参数和测试水分类,确定了测试水的来源。影响测试水分析的主要因素是取样条件。正确地应用测试资料、全面地了解测试地层的地质特征和测试水产状是准确确定真正水源的关键。这种判别碳酸盐岩测试水的方法,对类似地层也有参考意义。Because of the special geological structures in Tarim basin,it is quite complicated that the case of formation water comes forth by carbonate formation testing. The water coming from carbonate rocks or reservoirs could be divided into seven aqueous types by its geochemistry characteristic and water status. The source of the water has been confirmed according to its geochemistry characteristics, reference formation water charaeteristic parameters and water classification by taking the carbonate buried hill reservoir of Ordovician in Lunnan area of Tarim basin as an example. The main factor that influences the water analysis is the sampling condition. It is concluded that the key to properly determine the real aqueous source is to rightly use the infnrmation from formation testing and comprehensively understand the geological characteristic and the water occurrence. This method for distinguishing formation water and searching for the real aqueous sources is of some significance to other similar strata for reference.
