以井筒动力学为基础 ,系统地研究了拟均匀流态下气井井筒流体在关井、开井状态下 ,重力、摩擦力、动量、温度及含水对井筒压力分布的影响 ;确立了井口压力与井底压力的关系 ,研究了井筒流体密度的变化规律 ,并用建立的井口压力与井底压力的关系对长庆气田 2 0余口井的静压、流压值进行了推算 ,其值与实测结果接近。该研究成果的应用减少了测压作业次数 ,取得了较好的效果
Based on the wellbore dynamics, the effects of gravity, friction, momentum, temperature and water content on wellbore pressure distribution under wellbore flow were investigated systematically under wellbore flow conditions under wellbore conditions. Wellhead pressure and The relationship between the bottom hole pressure and the wellbore fluid density was studied and the relationship between the wellhead pressure and the bottom hole pressure was used to calculate the static pressure and the pressure value of more than 20 wells in Changqing gas field. The result is close. The application of the research results reduced the number of manometry operations and achieved good results
