油气田开发单井经济产能界限模型研究

在油气田开发过程中，单井产能的高低是影响油气田开发效益的主要因素，影响油气田单井产能的因素有：油藏构造及复杂程度、油藏储量丰度、油层性质（孔隙、渗透率、含有饱和度等）等。通过对油气田开发单井总投入与总产出的分析，建立了单井经济产能界限的模型，并结合油气田的实际情况，选取相应的参数，进行单井开发经济产能界限的计算和敏感性分析。为油气田加强单井管理、搞好目标成本分析，提供了数量化的、与经济效益相结合的依据。

Research on Single Well Economic Productivity Boundary Model in Oil and Gas Field Development

In development of oil/gas field, the single well productivity is a main factor to affect the oil/gas field development benefit. The factors that affect the single well productivity have: reservoir structure, abundance of reserves, reservoir properties (pores, permeability, oil saturation etc.) etc. Based on the analysis of total input and total output in single well development, the economic productivity boundary model in single well was established, and in combination with practical situation of oil/gas field, the calculation of economic productivity boundary and reservoir sensibility analysis in single well development were carried out by selecting corresponding parameters. The calculation and analysis results supply basis for enhancing the single well management and make target cost analysis.
