基于ABAQUS的深海复杂地层钻具钻进数值模拟研究
ABAQUS-Based Numerical Simulation Study on Drilling Tools in Complex Deep-Sea Formations
摘要
Abstract
In response to the challenges of deep-sea complex deep-sea formation drilling,a three-dimensional numerical model of the deep-sea formation-drilling tool system has been established based on the ABAQUS software platform so as to simulate the drilling process of the drilling process in different formations,thus verifying the applicability of the equipped drilling tools for deep-sea operations.By applying different drilling speed and weight-on-bit(WOB)parameters to the drilling tool,the rate of penetration(ROP)and the pressure distribution on the drill bit under varying conditions can be successfully obtained.The increase in feed rate is greater at low drilling speeds and high drilling pressures in hard formations,while the increase in feed rate is smaller at high drilling speeds and low drilling pressures.The pressure on the drill bit decreases as the drilling speed increases,with the decrease gradually accelerated.In hard formations,the decrease in pressure remains relatively stable and consistent,with the pressure reduction ratio increasing by merely 0.6%.关键词
