高凝油油藏注水开采温度场变化规律
摘要
Abstract
Some high pour point oil reservoirs have high wax content, wax precipitation point and set point. Wax deposition may damage reservoir porosity and permeability, and normal temperature water injection may change the seepage law. 2D water flooding physical simulation experiment is conducted to study the effect of different water temperatures and vertical well patterns on temperature field distribution, and the distribution of oil saturation in different well patterns is analyzed through numerical simulation. The research shows that water injection temperature has big influence on temperature field. It is suggested that the temperature of injected water shall be higher than the wax precipitation point for high pour point oil reservoirs developed by waterflooding, and five - spot pattern is preferable.关键词
