本文简单介绍了从70年代中期开始，西方国家研制、使用树脂涂层支撑剂的概况。由于该类支撑剂克服了传统支撑剂砂及陶粒固有的缺点，不仅防止了支撑剂被压碎及吐出的现象．也减少了支撑剂嵌入地层的弊病。另外，使用该类支撑剂还可防止细粉的运移，因此在较高的闭合应力下也能使裂缝保持较好的长期渗透率。目前美国许多油田已大量使用这类支撑剂以代替砂及陶粒。文中通过室内评价及现场使用实例说明它在水力压裂作业中的效天比传统支撑剂好，对油田增产作用显著。经济效益分析表明，它是一类最经济、合理很有发展前迫的新型水力压裂支撑剂。
This article briefly introduced the development and application of resin coated proppants in western countries since the mid 1970s. Since such proppant overcomes the inherent disadvantages of traditional proppant sand and ceramsite, it not only prevents the proppant from being crushed and spit out. It also reduces the drawbacks of proppants embedded in the formation. In addition, the use of this type of proppant also prevents the migration of fines and thus enables the fractures to maintain good long-term permeability at higher closure stresses. At present, many proppants in the United States have extensively used such proppants to replace sand and ceramsite. In this paper, indoor evaluation and field use examples show that it is effective in hydraulic fracturing operation than traditional proppants, and has a significant effect on oilfield yield increase. Economic analysis shows that it is a kind of new type of hydraulic fracturing proppant which is the most economical, reasonable and well-developed.
