曙光油田超稠油分层化学助排技术研究与应用

摘要

针对曙光油田超稠油原油粘度高，采注比低，油层纵向渗透率差异大的矛盾，以“措施到层”为技术思路，开展分层助排技术研究与应用。将笼统助排改为分层助排，实现油层的精细分层处理，使助排技术更具有针对性、合理性、科学性。通过现场应用表明，该技术有效改善了曙光油田超稠油油藏的开发效果，具有广阔的推广前景。%Aiming at high viscosity of crude oil, low injection production ratio and big vertical difference of reservoir permeability in Shuguang oilfield, research and application of layered cleanup technology were carried out, The general cleanup was replaced by layered cleanup, the fine layered processing of reservoir was realized, which could make the cleanup technology be more targeted, reasonable and scientific. Field application shows that the technology can effectively improve the development effect of super heavy oil reservoir of Shuguang oilfield, has broad popularizing prospect.
