查询词典 casing

Based on the study of the geological characteristics of drilling engineering at the Tongnanba belt, it is proposed to adopt optimal gas drilling, foam drilling, vertical drilling, compound drilling, rotary drilling and other drilling-oriented approaches to promote the fast and vertical drilling, to optimize the casing program and determine the appropriate casing sealing points to get proper hole sizes, to optimize drilling fluid performance to improve its anti-sloughing and lubrication capability, to stress bit selection to improve rock-breaking effects, and to take concrete lost circulation control measures to reduce non-productive time.
