Fiber reinforced plastic screen pipe completion technology of coalbed methane horizontal well

According to the fiber reinforced plastc screen pipe completon technicue with the stable maintained well a. igh eficient sand prevention.,ust prevention and anti-coosion.safety and economic realization of the pipestring reenterto complete the ru ellfushing and other advantages.based on the f.er reinforced plastic screen pipe completion techique as a new completion tfechnique an inovated design was conducted on the completon ofthe coaled metod hoizonta open welland PE screen pipe completion technology.The analysis on the fier reinfoced plastic sceen pe completion feaures and advantages shoved thth fi r renfocedplasic screen pipe with low frction factor would be favorable to the pipe string down sting operation.the f.er reinfoced lasti: screen pipe with a igh strength wouldcbe favorable to ensure the integration of the horizontal secional channel and could realize the tu e lfushing operation at thelate horzontal ell ection and the fi erreinforced plastic screen pipe with non-metallic material would be favorable to the savety mining operation at the lave of mine.T he fibrinoced platit sceen poe with a wash pipe as an internal pipe could set up drlling mud crculaton in the vwhole operaion process coul ffectively andlethe jaming phenomenon occuredin hescreen pipe down setting process,could eaize well fushing with high pressurized hyraulic jting and coud tnost reduce thersevoi faire ocurd it he previous operation process.The technique was appied to construct 32 gas wels io Shan i calbed imetan stie a total length of sc.een pipe down eting was 4 62 m and the successful rate was 100%./n adtition,the technique could play a promotion ole to the colbed methane development and calbed methane horzontal completion t chnique and technology development.
