人们一般以获取地层水样的方法,在室内测定其矿化度。所获取的地层水的水样,仅能代表地层中可流动的水,它不包含地层中不可流动的水。但是,地层中可流动的水的矿化度,与不可流动的水的矿化度可能有很大差异,尤其在油田注水开发以后,其差异将更大。这样,从水样中测定的矿化度,就难以全面而准确地反映地层水的总的矿化度,并且由此可能对测井解释产生不利影响。经研究,提出了一种更准确地确定地层水矿化度的思路和方法,应用于丘陵油田后,取得了较好的效果。 People generally use the method of obtaining formation water samples to measure their salinity indoors. The water sample of the acquired formation water can only represent the flowable water in the formation and it does not contain the non-flowable water in the formation. However, the salinity of flowable water in the formation may vary widely from that of non-flowable water, especially after the development of oilfield waterfloods. In this way, the degree of salinity determined from the water samples can not be fully and accurately reflected in the overall salinity of the formation water and, as a result, may adversely affect logging interpretation. Based on the research, a new idea and method to determine the salinity of formation water more accurately are put forward. After applying in the hilly oilfield, good results have been obtained.
