  • 摘要
    为了研究压裂液在煤层气压裂中的应用现状,提高压裂液与煤储层压裂技术的匹配从而提高压裂效果,对目前使用的活性水压裂液、交联冻胶压裂液、清洁压裂液和泡沫压裂液的性能与特点,以及各类型压裂液的应用现状进行了分析总结。分析认为活性水和交联冻胶压裂液配置简单、携砂能力强、使用范围广,仍是煤层气压裂液的主要类型;低压、低温、强水敏等有特殊要求的储层可使用泡沫压裂液、清洁压裂液等低伤害的压裂液。结合目前国内外最新进展阐述了氮气压裂液、增能压裂液、纳米压裂液、混合压裂液等新型压裂液的核心技术与特点。氮气压裂液使用液体氮气作为携砂载体,最大限度地降低了煤储层伤害;增能压裂液内部的化学反应产生的热量使其能够自动升温增压,在储层内部产生泡沫,达到和泡沫压裂液类似的效果;通过纳米技术对压裂液原料进行改性从而提高压裂液性能有望在压裂液研究上获得突破;混合压裂液结合了活性水与交联压裂液的优点。最后指出在满足低伤害、低成本、高效环保等技术指标的前提下,成熟压裂液优化和单剂研发、新型压裂液体系的研究突破口、压裂液返排液的回收利用是煤层气压裂液的研究方向。

    in order to study the application of facturing fuid in coalbed methane( CBM )frcturing and to improve the matcting of facturin fuid to coal reservoir and to improve the effect of fracturing.,the present stuation of fracturing fuids inlucing activie water frcturin fruid cross inked gel facturing fuid clean fracturing fuid and foan fracturing fuid was analyzed and summarized. Active water and crosslinked gel racturing fuid which configuration is simple, has stong carying capacity ndwide using range are the main kind of CBM fracturing fuid low pressure,ow temperature,stong water senstity specal requirements resevoir can use lov damage facturin fuid.such as foan fracturing fuid and clean.combining the latest progrss at home and abroad.thecore techmnology and features of the new fracurin fuid s.h as ntrogen fracturing fuid,energized,.nano fracturing fuid,mixed fracturing fuid are expounded in this paper.The ntrogen fracturing fuid usin liquid nirogen ascaner carier mininize the damage of coal sean: energized fracturing fuid can increase heat and pressure by the imtemnal chenical reacton and buble within the reserwor.which is sinilrto that ofoan fracturing fuid efrct, nodfication ofracturing fuid materials with nanotechnogy to improve fracturin fuid peromance is expected o get breakthrough in stucy of fracturing fuid.Mlixed fracturing fuid is a combiative advantages of ative water and cosslinking ractringfud.
