准噶尔盆地不同类型气藏商业气流标准研究

STUDY ON STANDARDS OF COMMERCIAL GAS FLOWS FROM DIFFERENT TYPES OF RESERVOIRS IN JUNGGAR BASIN

商业油气流是指在现今技术经济条件下,具有商业开采价值的最低单井初期稳定日产量。应用盈亏平衡原理和经济极限产量与商业气流的关系,建立了商业气流的基本计算模型。以准噶尔盆地不同类型气藏的特点和新疆油田的实际生产经营情况,对模型参数进行了界定,从而建立了准噶尔盆地不同类型气藏的商业气流标准和图版。通过对比分析和新疆油田的实际应用,认为准噶尔盆地商业气流和标准图版,符合新疆油田生产实际,具有较强的可操作性和实用性。

Commercial oil & gas flow refers to the minimum daily oil and gas production with commercial exploitation value from individual wells at early production stage under the current technical and economic conditions.Based on the relationship between the break even principle and economic limit production,a basic model is established for commercial gas flow calculation.According to characteristics of different reservoirs and the actual production and operation status,parameters are defined for the model and then the gas flow standards and charts have been established for different reservoirs in Junggar basin.Based on comparison,analysis and the actual application in Xinjiang oilfield,it is considered that the standards and charts for commercial gas flow in Junggar basin are practical and applicable for Xinjiang oilfield.
