摘　　要：循环压耗是制约钻井技术的关键因素,RMD技术作为一种极具潜力的新型油气井钻井方法,能够有效提升钻井效率。本文对RDM技术中直井段泥浆循环压耗计算公式进行了推导,分析了温度变化对泥浆主要流变参数的影响并将其代入计算公式中,发现直井段循环压耗总体上与温度呈反比的趋势,考虑地层温度纵向变化的直井段循环压耗为以20℃为固定温度的直井段循环压耗的88.5%。因此在实际工程中考虑地温对泥浆循环压耗的影响十分必要。Pressure loss of drilling mud is a critical factor restricting drilling technology.RDM technology,as a highly promising novel method for oil and gas well drilling,can effectively enhance drilling efficiency.This study derives the calculation formula for circulating pressure loss of drilling mud in vertical section with RDM technology,analyzes the effect of temperature variations on the primary rheological parameters of the mud,and incorporates these effects into the calculation formula.It is found that the pressure loss of drilling mud in the vertical section generally exhibits an inverse relationship with temperature.When considering the longitudinal variation of ground temperature,the pressure loss of drilling mud in the vertical section is 88.5% of that calculated at a fixed temperature of 20℃.Therefore,it is essential to account for the influence of ground temperature on pressure loss of drilling mud in practical engineering applications.
