液体火药高能气体压裂技术研究和在深层油气藏中的应用

高能气体压裂技术是最近发展起来的一种新型增产技术。从生产实际出发，根据中原油田油藏埋藏深、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。介绍了液体火药的优点、作用机理、配方、种类，以及选并原则和施工工艺。1997年至1999年在16口井进行现场试验，工艺成功率100％，截至1999年10月底，已累积增油6650t，取得了较好的效果。实践证明，液体火药高能气体压裂技术可极大地提高深层油气藏的采油效果，对于改善深层低渗透油气藏的开发状况具有广阔的应用前景。表3参2（叶显军摘）

The high energy gas fracturing technique of liquid explosive and its application in deep-seated oil and gas reservoirs

High energy gas fracturing (HEG) technique is an oil enhanced technique that was developed recently. This paper gives its basic mechanism and actual production situations. For deeply seated and lowly permeable oil reservoirs in Zhongyuan oil field, a series of liquid explosives were developed based on the application of HEG of solid explosive. This paper gives their action mechanism,formulation and series, as well as the well-choosing methods and operation techniques of liquid explosives. Its application in 16 oil walls in 1997 and 1999 totally increased oil of 6650t. This proves that high energy gas fracturing technique can improve the production effectivenere of deep-seated oil and gas raservoirs and have a broad application potential in deep low permeability oil and gas reservoirs.
