摘要: 现行的工业油流标准作为地质储量的起算标准,经过50多年的争论、演化和应用,证明其仍然具有一定的现实意义,部分体现了以经济效益为中心的理念;但对低渗透及特低渗透储层,特别是对于须采取酸化及压裂等增产措施的储层,衡量其是否达到工业油流标准时应使用单井稳定产量。稳定产量与试油初期瞬时高峰产量的比值一般为2/5~1/8,不同地区、不同物性条件的储层有所差异。尽管提高措施强度可以提高试油初期的瞬时高峰产量,但稳定产量的大小最终取决于储层厚度与渗透率的乘积。对于低渗低产储层,由于层间的相互干扰,合层测试产量与分层测试产量之间并非简单的求和关系。

Abstract: The current commercial oil flow standard is only the lowest limit for original oil in place calculation. More than 50 years' practice proved that the current standard for commercial oil flow is still available. The ratio of steady production to testing peak production is usually in the range of 2/5 to 1/8. The ratio value is various for the different reservoirs with variant physical properties in different area. Although the testing peak production can increase when enhancing the fracturing intensity,the steady production of every well depends on the product of net pay and permeability of reservoir. The production of combined test is unequal to the total production of all reservoirs,because of the mutual interference among reservoirs for the low-permeability and low-production reservoir.

Key words: reservoir, crude oil, original oil in place, commercial oil flow standard, fracturing, production testing
