摘　　要：借助新研制成功的钻井液高温高压密度模拟实验装置 ,建立了泡沫钻井液高温高压密度特性模拟实验方法 ;并针对 3种欠平衡泡沫钻井液配方 ,分别开展了高温高压密度特性模拟实验研究 ,得出稳定泡沫钻井液体系密度随温度和压力的变化规律 。By means of simulating instruments recently developed, the experimental method of measuring the density of foam fluids under high temperature and high pressure (HTHP) conditions is established. Based on three kinds of under balanced foam fluids, studies on HTHP Density Characteristics Simulating Test are made and the effects of the foam drilling fluids static density changed with temperature and pressure obtained. The research establishes the strong foundation for the further studies of accurately predicting the static downhole pressure of under balanced drilling fluids.
