Analysis of Reasonable Casing Head Pressure on High-Gas-Oil Ratio Artificial Lifted Wells

Gao 52 Chang X is in the Changqing oilfield,in 2007 to invest in developing the high-gas-oil ratio,the difference between reservoir pressure and saturation pressure is small in this district,the flowing pressure always lower than the saturation pressure.The normal production wells were influenced by the gas.Usually control the sets of casing head pressure is under the field experience,the casing head pressure ranging from 1~5MPa.Production data indicate that casing head pressure is too high or too low,all affecting oil production fluid situation.This paper is based on production data and by multiple linear regressions to determine a reasonable set of casing head pressure on Gao52 highgas-oil ratio production wells,as well provides the necessary theoretical basis for production management.
