摘要
浅海油田井筒压力计算的准确性有利于保障油田的高效生产与开发。针对海上油田井筒管柱特点,运用油藏工程软件,建立单井井筒管流模型,选用不同运算方法,计算单井井底压力。通过实例计算,优选出适合于浅海油田的井筒计算方法,并根据A油田实际特点,推荐了相应适合的井筒压力计算方法。该计算方法计算值与实际值相对误差小于5%,可准确反映井筒实际管流特征。
The accuracy of wellbore pressure calculation in shallow-sea oilfield is conducive to the efficient production and development of oilfield.Based on the characteristics of wellbore in offshore oilfield, the wellbore flowing models are established with petroleum software.The bottom-hole pressure is calculated with different methods.The calculation methods suitable for offshore oilfield are optimized by examples.And the best method for oilfield A is recommended.The relative error between the calculated value and the actual value of the method is less than 5 %,which can accurately reflect the actual pipeline flow characteristics of the wellbore.
