Development and application of constant injection pressure automatic control system 增压泵恒压注水自动控制系统的开发与应用
Anaphylactoid experiment, with single intravenous dose of constant injection, observed changes in behavior of animals after administration and the concentration of histamine. 类过敏实验以单次静脉恒速注射给药,观察给药后动物的行为变化和血中组胺含量。
Under such circumstances, maintaining constant injection of water, improving the ground water pressure, when the stress reached the formation fracture pressure, there will be along the perpendicular to the direction of minimum principal stress fractures. 在这种情况下,保持注水量不变,提高地面注水压力,当井底压力达到地层破裂压力时,就会在沿垂直于最小主应力方向产生裂缝。
As a result, it was found that injection speed could be increased through varying nozzle port opening width under keeping constant injection pressure. 实验结果表明,在压力恒定的条件下,可通过控制喷嘴开启量大小获得不同的注射充填速度。
Constant flow blanking plug is an important component in the layered water injection system of oil field, when the injection pressure and strata pressure are changing, it can ensure that the flow rate of injection is nearly constant, so getting the purpose of constant flow injection. 恒流堵塞器是油田分层注水系统中的重要部件,在注水压力和地层压力变化时,它可以保证注水流量基本不变,从而达到恒流注水的目的。
