摘要
介绍了采用旋转射流水力喷射钻径向水平井的原理及技术关键． 对该技术进行了室内破岩试验、地面全尺寸模拟水平钻进试验以及现场井下破岩钻井试验， 结果表明旋转射流的破岩能力完全可以满足径向水平井的要求． 现场试验的成功表明了该项技术是可行的， 并对开采我国东部油区剩余油、提高采收率有十分重要的现实意义．
The principle and the key points of the spining jets with hydraulic jet for drilling radial horizontal wells have been stated.The technique have been used for breaking rocks and ground full?scale simulating horizotal drillings in laboratory tests as well as for breaking rocks in the field test.The results have shown that the capacity of the spining jet for breaking rocks can entirely meat the demands of the radial horizontal wells.The feasibility of the technique has been indicated by the successful field tests.
