n: The gas-holder tank connected with discharge line of reciprocal pump. It is a air cushion aerated by compressive air, used to absorb or decrease fluctuation of pressure and delivery capacity disproportion when reciprocal pump works.

n: The phenomenon that drill bit is damaged by friction due to high rotate speed or small delivery capacity in drilling.

n: Broadening delivery capacity of drill fluid and bit hydraulic horsepower to improve advance rate by using two or more pumps at the same time.

n: The sedimentary centrifugal whose entry presents cylinder and other part presents cone. This kind of centrifugal has bigger delivery capacity comparing with conic centrifugal in the same working parameter, maximal outside diameter and length.

n: The critical well depth is the well depth that The mode of operation of drill pump changes from peak discharge to adjusting delivery capacity. The limited well depth is the well depth that delivery capacity decreases to the minimum delivery capacity for c

n: (DCQ) that daily quantity of gas, formulated on some basis (usually a combination of reserves and delivery capacity or delivery capacity only). that the pipeline company will attempt to take;mayor may not equal the take-or-pay quantity.

n: (DC) the total daily rate that seller maintains and can deliver on demand over an extended period to buyer. delivery gas n: natural gas delivered to a distribution point, such as a gas plant or a city gate. Compare redelivery gas.

n: A method of examining overflowing or leakage in the wellbore. Acquiring difference of circulating rate by computing the difference of delivery capacity and return flow of pump with electro magnetic current meter.

n: the phenomenon that diamand burned out or softened because of overheated caused by scarce delivery capacity of drill fluid versized drill pressure when adamantine drill working under the bottom of well。

n: the drilling pump increase the delivery capacity of drilling fluid with big cylinder liner or increasing the dashing amount
