摘要
靖边油田孔隙度小、渗透性差,传统爆燃压裂后容易形成近井致密,在固体火药高能气体压裂应用的基础上,开发研制了液体火药,介绍了液体火药的作用机理和选井条件,计算了液体火药的注入位置。靖边油田现场试验表明,工艺成功率达100%,施工后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低渗透油藏的措施效果,具有广阔的应用前景。
Because of small porosity and low permeability of Jingbian oilfield,the rock near the borehole is easy to be tight after the traditional HEGF.In order to solve this problem,a new HEGF with liquid powder is developed.In this paper,the liquid formula is studied,the mechanism of new technique,the injetting position and the well selection conditions are introduced.The oilfiled results show that the construction success rate is 100%,also it has better economic results.Practice has proved that this HEGF technology which can greatly improve the effects of low permeability reservoir has a broad prospects.
