摘要: 在一定条件下,井底净化效率是影响钻速的重要因素。喷射钻头如果具有完善的井底流场设计,就能够及时地、连续而且稳定地有效净化井底,减少以至消除岩屑在井底的重复破碎现象。研究表明,要进一步发掘喷射钻井技术的潜力,仅仅对现有工作方式进行选择和在水力参数上进行调整是有限的、不够完善的。

Abstract: On some conditions the efficency of cleaning of the bottom-hole is the most important factor that affect the rate of penetration. If the design of the bottom-hole flow field is perfect, regrinding of cuttings can he reduced, and even eliminated. Our sturdy shows that in order to develop the potentiality of jet drilling it is not enough only to make a choice of the existing approaches and adjust the hydraulic parameters
