摘要

聚合醇对油气层的伤害性小

具有抑制性强

润滑性好

荧光级别低

不干扰录井

可生物降解

毒性低、价格低廉等优点

被应用于国内外油田钻井作业中。本文综述了国内外对聚合醇在抑制性、润滑性、流型调节三个方面研究进展

以抑制性为主

重点阐述了聚合醇抑制机理学说:浊点理论、渗透理论和吸附理论

三种学说很好的论证了聚合醇的抑制性能

但是都存在一定的局限性。针对现场应用出现的问题

介绍了近些年聚合醇在疏水改性、纳米材料改性、离子液改性几个方面的研究现状

其抑制性与稳定性都得到了提升。同时也对聚合醇今后的发展走向及应用前景进行了展望。

Abstract

Polyalcohol has the advantages of less damage to oil and gas reservoir

strong inhibition

good lubricity

low fluorescence level

no interference with logging

biodegradability

low toxicity and low price. It is applied in oil field drilling operation at home and abroad. In this paper

the research progress in inhibition

lubricity and flow pattern regulation of polyols at home and abroad is reviewed. The inhibition mechanism of polyols is mainly elaborated: cloud point theory

permeation theory and adsorption theory. The inhibition performance of polyols is well demonstrated by the three theories

but there are some limitations. In view of the problems in field application

the research status of hydrophobic modification

nano material modification and ionic liquid modification of polyols in recent years was introduced in detail

and its inhibition and stability were improved. At the same time

the development trend and application prospect of polyols in the future were also prospected.
