目前在我国已开发油田当中,基本都已经进入了开发中后期阶段,然而在这些油田中,低渗透油田所占比例大于50%,因此有必要对开发中后期低渗透油田进行研究。针对已开发油田,具体采用哪种方法计算储量,大体上是由勘探开发程度、地质特征、驱动类型等情况决定的。计算储量的方法目前有很多,本文针对X油田低渗透的特点,结合各种计算方法的适应性,选取容积法对X油田储量进行复算,所得结论对X油田的进一步认识和开发具有重要的指导意义。
At present, among the developed oilfields in our country, the basic ones have already entered the middle and late stages of development. However, in these fields, the proportion of low-permeability oilfields is more than 50%, so it is necessary to study the development of low-permeability oilfields in the middle and later stages. For developed oilfields, which method is used to calculate reserves is generally determined by the degree of exploration and development, geological characteristics and driving types. There are many methods for calculating reserves. In view of the low permeability of X oilfield and the adaptability of various calculation methods, the volumetric method is used to recalculate the reserves of X oilfield. The conclusion is of great importance for the further understanding and development of X oilfield Guiding significance.
