The Production And Management Technology Of Sulige Gas Fields

First, this article determine the classification of the Sulige gas field wells through the studies of reservoir physical parameters and the production of dynamic in Sulige gas field, the Su-14well area, peach2well area and Su-48well area, and through the combination with geological characteristics and development characteristics of gas wells, through dynamic and comprehensive classification to three wells a total of538wells.Then we preferred34wells which are easy to calculate and analysis from three types of wells from three scenic Sulige gas field after comprehensive classifications through all kinds of the wells pressure drop equation and the establishment of the productivity equation. After this we gives a reasonable production allocation of the various types of gas wells.In this process, we consider three factors which are the gas wells do not produce a reasonable allocation of non-Darcy effects production, airflow can carry out of gas condensate water and a small amount into possession of stagnant water, the minimum critical liquid carrying flow and gas well conditions to meet the maximum yield under the minimum wellhead lose pressure conditions in the production process.Third, we simulate the operating parameters of the Sulige gas fields skeleton tube network security by the application of TGNET software and demonstrate the rationality of the parameters of the Sulige gas fields skeleton pipeline network running under normal circumstances.Finally, we identify the large pressure drop pipeline in peaking run through the simulation and analysis of the skeleton pipeline network peaking run parameters in Sulige gas field, and we design vice tube design for these pipelines, thus peaking run skeleton pipe network model is optimized.
