摘　　要：充填防砂在稠油水平井的开采方面获得了成功应用,水平井压裂充填技术是在此基础上将充填防砂技术从充填发展到压裂充填,增加了酸洗清除泥饼工艺,并移植到稀油水平井上进行应用。以河南油田泌304区为例进行了研究,水平井压裂充填完井技术综合应用了精细滤砂管完井、酸洗、压裂充填等工艺技术,所有工序通过一趟管就可以完成,施工非常方便,地层污染小。通过安平2井等4口井的实施,产能比同层开采直井提高了3～10倍,且稳产效果好。The technique of packing sand control has successfully applied in the development of horizontal heavy crude oil wells.The fracturing and packing technique of horizontal wells was developed from the techniques of packing and then the fracturing packing,and the technique of acid cleaning of mud cake was added to it,and then it was transferred to the horizontal thin oil wells.Well Bim304 was taken for instance,the techniques of fracturing packing completion of horizontal wells,synthetical use of the technique is introduced in screen completion,acid cleaning,fracturing packing etc.All working process were completed only by one pipe string,it was very convenient with less formation damage.It is used in 4 wells such as Well Anpin 2,etc,the production increase is 3 to 10 times that of the production in the same zone compared to the straight wells.
