Study on the Model Applicability of Wellbore Pressure Disteibution Rule in Aeration Drilliing

更新时间:2015-07-27

【摘要】In order to be adapted to the development of the low-pressure drilling,aerate drilling technology was developed.It has advantages of high-capability of carrying cuttings,reducing the leakage,greatly improving the mechanical drilling speed,protecting low-pressure oil and gas reservoir,and little formation damage,etc.Guo model and Beggs-Brill model which are gas-liquid two-phase flow theoretical models commonly used in aeration drilling of are compared to analyze the respective advantages and disadvantages.
