摘　　要：高能气体压裂 (HEGF)技术是近几年发展起来的一种新型增产技术。本文简述了其原理 ,并从中原油田生产实际出发 ,根据其油藏埋藏深、地层渗透性差的特点 ,在固体火药高能气体压裂应用的基础上 ,开发研制了系列液体火药 ,介绍了液体火药的作用机理 ,液体火药配方研究、种类 ,液体火药的优点 ,以及选井原则和施工工艺。通过 1997年和 1999年在 16口井推广应用 ,工艺成功率达 10 0 %。截至 1999年 12月底 ,已累积增油 6650t ,取得了较好的经济效果。实践证明 ,液体火药高能气体压裂技术可大幅度提高深层油气藏的HEGF措施效果 ,改善深层低渗油气藏的开发状况 ,具有广阔的应用前景。The High Energy Gas Fracturing (HEGF) technique is a stimulation treatment that is developed recently.Combining the production situations with deep,poor permeability of hydrocarbon reservoir in Z hongyuan Oil Field,a series of liquid explosive are developed.This paper introdu ces the mechanism and action of the liquid explosive,and presents its formulat ion,types,advantages,well choosing principle and operation technology.Wide appli cation of the technique in 16 wells in Zhongyuan Oil Field in 1997 and 1999,good results are received,and the success ratio is 100 percent.By the end of 1999,th e accumulated oil production is 6 650 t.It is concluded that the HEGF technique with liquid explosive can largely increase the stimulation results in deep and p oor permeabile reservoirs.
