| 摘 要： | 在充气泥浆流体流动特性的基础上,建立连续油管钻井作业的摩阻计算模型,计算地面滚筒压降。井内压降,计算结果表明连续油管作业压耗比常规钻井中的压耗高,对钻井注入压力有较高要求。

| Abstract: | In this paper,coiled tubing drilling friction model is established on the basis of the fluid flow characteristics of aerated mud,the ground roller pressure drop and the well pressure drop are calculated,the results show that the coiled tubing pressure drop is higher than the regular drilling,giving the higher requirement on injection pressure. |

| Keywords: | coiled tubing under-balanced aerated mud friction injection pressure |
