考虑海拔和空气湿度对空气钻井流量的影响

Considering How Altitude and Air Humidity Influence the Air Drilling Flowing Velocity

本文重点讨论了空气钻井流量模型的建立,为空气钻井提供了必要理论依据,修正以往的模型,考虑地面海拔以及空气湿度对空气钻井流量的影响。根据所建立的模型编制应用软件,计算空气钻井最小流量。结合现场实践,达到指导实际空气钻井的目的。

This paper makes an important discussion about the foundation of air drilling velocity model which provides necessary theoretic basis for air drilling.It also rectifies former models and considers the impact that altitude and air drilling have on the air drilling velocity.It compiles an applicant software according to the established model and calculates the lowest air drilling velocity,attaining the goal of guiding the actual air drilling.
