摘要
高压射流辅助钻井破岩一直是石油天然气钻井界研究的重要课题。文章对产生高压射流的增压方法进行了分类 ,介绍了井下增压的两种方法及原理 ,即井下机械增压方法和井下水力增压方法。重点阐述了提出的井下水力增压的原理、方法及初步探索的阶段性成果 。
High pressure jet to crack rocks for assisting drilling has always been an important research subject explored by the well drilling sector.The article classifies the boosting methods which create high pressure jet flow,and introduces two methods and principle for down hole boosting,which are down hole mechanical boosting method and down hole hydraulic boosting method.The article mainly describes the principle,method, and the preliminary research results of down hole hydraulic boosting,which establish the theoretical base to study the down hole hydraulic booster
