| 摘 要： | 井底环空循环吸入式粒子射流钻井是解决硬地层破岩钻井效率低下的有效途径。采用所研制的井底围压试验装置,试验探索井底环空循环吸入式粒子射流破岩的规律。结果表明:随着围压的增大,粒子射流破岩效率逐渐减小;随着射流压力、粒子直径和硬度的增大,粒子射流破岩效率逐渐增大;随着喷距和粒子质量分数的增大,射流破岩效率呈现先增大后减小的趋势;井底环空循环吸入式粒子射流高效破岩钻井方法确实可行。

| Abstract: | Using the particle jet drilling technology with circulatory suck-in bottom-hole annulus fluid is a way to solve the problem of the low rock breaking efficiency in hard formation.The rock breaking rules of particle jet circulatory suck-in bottom-hole annulus fluid were studied with the ambient pressure experimental equipment designed.The results show that the rock breaking efficiency decreases with the ambient pressure increasing.The rock breaking efficiency of particle jet increases with the pressure,partic... |
