摘要
鲁2块油藏是吐玉克油田原油粘度最大、埋藏最浅的稠油油藏。本文通过对鲁2井脱气原油物理性质和流变特征的物理模拟实验,确定了稠油类型,通过对不同温度下脱气原油的剪切应力、剪切速率、对应粘度的测试,及各参数对应关系的分析确定了不同温度下流体的流变类型、触变性特征和流变模式,并且分析了不同温度下的流体对油田开发的影响,为油田的开发设计提供了依据。
Lu-2 reservoir is the heavy reservoir in Tuyuke Oilfield which the viscosity is the highest and the buried depth is the shallowest. Through the physical simulation test of physical property and rheological behavior of degassed crude of Well Lu-2, the heavy oil categories were determined. By means of testing shear stress, shear rate, correspondence viscosity of degassed crude in various temperature, and analyzing correspondence relation of the parameters, the paper also determined the fluid rheological category, thixotropic behavior, rheological pattern in different temperature and the influence upon oilfield development, and provided the basis for the oilfield development and design.
