摘要
本文模拟港西聚合物驱试验区的实际油藏条件,结合井组先导性试验中暴露出来的主要问题,应用室内物理模拟试验技术,开展了聚合物驱油剂与油层适应性试验。研究了聚合物驱油剂增粘性、抗机械降解性、稳定性、注入性及驱油性与油层的适应性。并通过聚合物分子量和油层渗透率的配伍性研究,建立了港西四区不同渗透率油层聚合物的驱油特征和驱油剂的优选标准。本文还研究了不同分子结构聚合物的驱油性能,并优选出了适用于港西四区聚合物驱工业性试验用的聚合物驱油剂。
According to the problems discovered in the pilot polymer flood test in Gangxi oilfield, a suitability test for the polymer used in the development of this reservoir was carried by applying in-house physical modelling technique under a simulation reservoir condition. The characteristics of polymer under reservoir condition used as viscosification,shearing stability, stability, injectivity and oil displacement ability were investigated and the standard for polymer screening compatible to different permeability layers in the reservoir in No. 4 area, Gangxi oilfield was set up. Oil displacing ability polymer with different molecular structures was also investigated. Finally, the most suitable polymer used for oil displacement in No. 4 area Gangxi oilfield was suggested.
