浅谈高气油比机采井正常生产时的合理套压

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

高52长X区块是长庆油田2007年投入开发的高气油比油田，该区地饱压差小，生产流压均低于饱和压力，油井正常生产时受气体影响较大，通常根据现场经验控制套压在1～5MPa。生产数据表明，套压过高或过低均影响油井的产液情况。以不同套压下测试的生产数据为基础，通过多元线性回归，确定了高52高气油比机采井正常生产时的合理套压，为油井的生产管理提供了必要的理论依据。

Gao 52 Chang X is in the Changqing oilfield,in 2007 to invest in developing the high-gasoil 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 15 MPa. 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.
