摘要
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。
The salinity of formation water used to be normally measured in laboratory with in-situ forma-tion water sample.The acquired formation water sample only characterizes in-situ movable water rather than unmovable water,both of which there possibly exists distinct difference in salinity.Particularly,such a differ-ence may appear much bigger than before following water flood development of an oilfield.At the result,the measured salinity from the water sample is hard to reflect the total salinity of formation water comprehensively and accurately,thus leading to detrimental effect of corresponding well log interpretation.This study presents a more accurate thought or method for determination of the salinity of formation water,and better results have been gained followed by application of it in Qiuling oilfield.
