The gas will effect the pump efficiency of deep well-pump, if the amount of the gas of oil well is large, even gas locking occurs.

如果油井产出气量较大，则这些气体对深井泵的泵效将产生很大影响，严重的井甚至发生气锁。

The increased gas volume in the wellbore resulted in frequent gas locking of the ESP, which resulted in little to no liquid flowing past the motor and through the pump.

随着井内气体量增加，进一步造成ESP频繁气锁，最终泵只能举升少量甚至举升不出液体。

The BP deal guarantees Sempra gas at a discount to the price on the U.S.-Mexico border, locking in a nice spread.
