METHOD OF DISTRIBUTION OF OIL WITHDRAWAL BETWEEN BLOWER AND GAS-LIFT WELLS Russian patent published in 2009 - IPC E21B43/00 E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to process of optimal withdrawal of production from wells operated by blowing and gas-lift methods. The essence of the invention is like follows: the method consists in measurement of technological parameters of wells such as gas consumption, oil yield, buffer pressure, watering, in conversion of parameters and processing, then in building static models of a well, in experimental investigation of process parameters of the well, in checking model adequacy; in development of algorithms of oil withdrawal distribution between wells. By regulating diameters of connecting branches such mode of well operation is established that the total oil yield of concrete blowers and gas-lift wells will satisfy a required production quota for oil withdrawal for a group of wells or for oil field cluster. Also the sum of actual gas consumption for blowers and working gas for gas-lift separate wells is reduced to a minimum providing trouble-free operation of wells and not allowing process troubles on them.

EFFECT: increased efficiency of method due to optimisation of operation modes of blowers and gas-lift wells.
