Experimental Study On Producing Wells In Sulige Gas Field Management And Drainage Gas Technology

Sulige gas field is the low yield, low pressure, low permeability, low abundance, strong heterogeneity of complex gas field, with the development and expansion of the scale of the deepening, increasing water production wells, water production increases, gas production capacity universal low, drainage work have become increasingly prominent.To carry out this study four aspects of drainage gas, mainly from fluid technology to optimize well Mopai bubble discharge drainage, new technology and new technology, process analysis, analysis of the applicability of the research work, comparative analysis of the effect of gas drainage process technology to carry out the process suitability and economic evaluation in order to establish the Sulige gas field of gas drainage technology series, to guide the field of low-yielding wells inefficient management and steady production. Meanwhile, the paper also fluid and gas production on water analyzes, water control countermeasures for further discussion, in which the foam drainage gas technology, coiled tubing gas drainage technologies, plunger gas lift gas drainage technologies other technology methods were studied in detail, and gas lift compressor method, nitrogen gas lift method and the single well supercharging to enhance the ability of gas drainage methods are analyzed, and finally, in consideration of the impact of the situation down the column Calculation of the parameters.
