n: an equation that can be used to make calculating the maximum amount of casing pressure to expect when a gas kick is circulated out of a shut- in well more accurately reflect reality.
کنتور حجم
a reservoir drive mechanism provided by the expansion of solution gas in the oil.
n: 1. actual volume of fluid put out by a pump, divided by the volume displaced by a piston or pistons (or other device) in the pump. Volumetric efficiency is usually expressed as a percentage. For example, if the pump pistons displace 300 cubic inches (4,916 cubic centimetres),but the pump puts out only 291 cubic inches (4,769 cubic centimteres) per stroke, then the volumetric efficiency of the pump is 97%. 2. for compressors, the ratio of the volume of gas actually delivered, corrected to suction temperature and pressure, to the piston displacement.
جریان سنج حجمی
n: The rock be breaked into big blocks,when bit weight per unit area equal to or exceed the hardness of rock.
n: The loss caused by the leakoff of high pressure liquid at the gapping of piston and cylinder liner,valve and valve seat or piston rod and where its sealed.
n: a method of well control in which bottomhole pressure is kept constant when circulation is not possible and gas is migrating up the hole. Bottom- hole pressure is maintained slightly higher than formation pressure while the gas is allowed to expand in a controlled manner as it moves to the surface.
n: A kind of ways of well control when snubbing service,which blowoff or imput same volumic drilling fluids to complement the difference in pressure.
n: pooling of leased tracts willingly undertaken by all the parties involved, both working interest owners and royalty owners.
n: standards established generally by private sector bodies for use by any person or organization. Includes what are commonly referred to as industry standards and consensus standards, but does not include professional standards of personal conduct, institutional codes of ethics, private standards of individual firms, or standards mandated by law.
