Present situation and development of coalbed methane fracturing fluid

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.
