1) pressure loss
压耗
2) annular pressure loss
环空压耗
1.
Casing program design of mega-extended-reach wells is complex,and in order to design in reason its casing program,based on the principle of pressure balances in the casing program design in the vertical wells,the relationships among pore pressure,fracture pressure and annular pressure loss in the long open-hole section with high inclination in mega-extended-reach wells are discussed.
超大位移井井身结构复杂,为合理设计其井身结构,从垂直井井身结构设计的压力平衡原理出发,针对大斜度井段垂深变化小且裸眼井段很长、大斜度裸眼井段最容易在测深最大处被压裂的特点,通过计算钻井液的当量循环密度,研究了超大位移井大斜度裸眼井段的地层压力、破裂压力和环空压耗之间的关系,得出套管最大下深及允许最大环空压耗的计算公式。
3) system pressure consumption
系统压耗
4) cyclic pressure dissipation
循环压耗
1.
Accurate calculation of cyclic pressure dissipation is the basis of programming of bit hydraulics optimization.
循环压耗的准确计算是钻头水力参数优化程序设计的基础。
5) low pressure and low consumption
低压低耗
1.
Furthermore the features of the upturning situation in gas industry are as follows:development and operation of small air separation plants with low pressure and low consumption;emerging central oxygen supply in region ;seeking for coordinate dev.
