摘要
稠油油田大多数具有高渗透、易出砂的特点。其生产压差较小,引起压力恢复曲线的直线段斜率较小且长度较短,因此很容易受到其它因素的干扰。本文讨论了'驼峰'现象和潮汐对海上稠油油田压力恢复曲线的影响。指出稠油油田容易产生'驼峰'现象,并受潮汐的影响。样板曲线解释方法不适合有'驼峰'现象的压力恢复曲线.而用豪诺法解释为好。
Thick oil fields are characteristically of high permeability,sand production and low pressure drawdown. Besides linear lines of their build up curves commonlv have small shope and short length, and therefore are subject to distortion bv a number of factors. This paper discusses effect of 'humping pressure' and marine tide on build up curves as they frequentlv present themselves in a thick oil field offshore. In addition, the paper recommends Horner method regarding interpretation of a 'humped'build up curve to which the method of type match is believed to be less applicable.
