The Reseach Of The Different Types Node Pressure Of Gas In Jingbian Gas Field

Jingbian gas field is the main gas field of Changqing gas field, From the field in general terms, most wells are producing water, The bottom hole pressure gas back has a substantial increase,the gas production declining, some wells even appear Bottom hole liquid situation,which may cause serious flooding, resulting in gas cut-off,this paper, under the specific circumstances of Jingbian, which study the calculation of node pressure gas wells and liquid carrying capacity of shaft. Then according to Jingbian field actual data,calculate the comparative analysis of the accuracy of each method, by setting the node of each link of the pressure loss,the study determined for different diameters, bottom hole pressure is different, the minimum liquid production is different, and the larger diameter, nozzle diameter, the greater the pressure loss of the entire production system the smaller the diameter of the smaller, gas nozzle The smaller, the greater the pressure loss of production systems, high yields can not be normal production. The reasons for the modification of different measures to reduce the pressure loss of gas well production, to ensure normal production of gas wells.Finally, according to the practical needs of different gas field of Jingbian well, through a variety of production system analysis of the pressure loss.in the different working parameters, the formation of different wellbore fluid flow patterns, and form a lower pressure loss as the goal of reasonable working system.
