Jet mill bit for improving cuttings carrying capacity in horizontal gas drilling
摘要:Cuttings accumulation is a major challenge in horizontal gas drilling, it may lead to accidents such as wellbore plugging and pipe sticking. The newly-developed jet mill bit (JMB) may overcome the challenge fundamentally by comminuting cuttings into dusk-like scale right after the cuttings are generated. In this paper, the JMB is investigated as an innovative method to improve cuttings carrying capacity in horizontal gas drilling. It presents the JMB's working principle and cuttings-comminuting mechanism, and explains why it is developed based on the analysis of cuttings carrying capacity in horizontal gas drilling. Analysis using field data in the published article demonstrates that the max cuttings that can be carried by the annular gas are dust-like and much smaller than the initial cuttings size in the high angle build section and horizontal sections, it needs several times as much gas injection volume as the current annular gas injection volume to eliminate cuttings accumulation. JMB can comminute cuttings in dusk-like scale and may eliminate cuttings accumulation fundamentally, meanwhile drilling complications such as near bit hole washout, hole deviation, and ice-balling (frozen) of bit can also be avoided in horizontal gas drilling.
