油田单井最低产量分析方法研究

RESEARCH ON ANALYTICAL METHOD FOR MINIMUM WELL YIELD OF OIL FIELD

在油田经济评价中,单井产量的高低是一个很重要的参数,它直接影响开发建设投资的大小和油气经济评价的最终效果。文章通过对影响油田单井产量的参数进行分析和测算,运用投资和成本之间的关系,建立相应的数学模型,测算出油田开发单井最低产量,并对最要的影响因素进行敏感性分析,确定各自对油田单井最低产量的影响程度。其分析和计算方法可以用于石油和天然气开发建设经济评价初期的测算,方法简单、易行,具有较强的可操作性。

In economic assessment of oilfield, the quantity of well yield is an important parameter. It influences the investment's magnitude of development & construction and the ultimate benefit of oil & gas economic assessment directly. Through analyzing and calculating the parameters which influence well yield of oilfield, the paper establishes the corresponding mathematic model with the application of relationships between investment and cost, calculates the minimum well yield of oilfield, and carries a sensitive analysis on the important influencing factors in order to determine each factor's influencing degree to the minimum well yield of oilfield. Its analytical and calculating method can be used into the surveying of economic assessment on petroleum and natural gas development & construction in initial stage. The method is simple, feasible, and has strong operability.
