东北石油大学本科生毕业设计（论文） 摘 要 海洋油层深部调剖技术自20世纪70年代初开始大规模的商业应用，研究发展很快，现已成为高含水期油田改善水驱效果的主导技术。目前，针对海洋油藏开发出的调剖剂和堵水剂种类繁多，应用较为广泛的是油溶性树脂。施工时，可将水基树脂悬浮液与压裂砂混合后挤入地层，在地温下树脂可在一定时间内自行交联，将水层堵住。本文简要介绍了油溶性有机树脂的室内实验分析结果，并对将油溶性树脂加入钻井液中进行了实验分析。通过对树脂的主要性能及钻井液的性能指标进行分析评价，发现油溶性树脂的油溶率可达95%以上，耐高温，软化点在80-120℃之间，对钻井液的性能有改善的效果。对比实验发现，④ 关键词：耐高温；油溶性树脂；海水钻井液 Abstract Since the beginning of 1970s, marine reservoir deep profile control technology has been used to large-scale commercial application, which obtains shoot development .And now it has become a dominant technology to improve the water flooding effects of oil field in high water-cut period. Currently, the developed profile control agents and blocking agents for marine reservoi are various, of which oil-soluble resin is more extensive. When constructing, we can first mix water-based resin slurry with sand after fracturing, and then squeeze them into the strata. Under the temperature, resin can be self-crosslinking within a certain period of time. Then the water layers will be blocked. This paper describes briefly the laboratory analysis results of oil-soluble organic resin, and make a analysis after accede in the sea water drilling fluid . Through analysising and evaluating the main performance indicators of the resin, we found that the oil rate of the Resin is more than 95%, high temperature, the softening point is between 80℃ and 120℃,and it is useful for sea water drilling fluid. The results show that, comparing with similar products, the number Four resin owns more advantages. Conclusions from the experiment are drawn as follows: the resin can be capable of offs Keywords: high temperature; sea water drilling fluid; oil soluble resin 东北石油大学本科生毕业设计（论文） PAGE I 目 录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc263769526 第1章 概 述 PAGEREF _Toc263769526 \h 1 HYPERLINK \l _Toc263769527 1.1海水钻井液技术的形成与发展 PAGEREF _Toc263769527 \h 1 HYPERLINK \l _Toc263769528 1.2 油溶性树脂研究的目的及意义 PAGEREF _Toc263769528 \h 3 HYPERLINK \l _Toc263769529 1.3 国内外研究油溶性树脂的现状 PAGE
