摘要
将油田开发全过程作为经济评价期，根据谢尔卡切夫公式计算最终累计采出油量及相应的伴生气产量，从而求出总产值、总经营成本，并依据新的税收制度考虑销售税金、资源税、原油商品率、固定投资贷款利率等经济指标，导出了随井网密度变化的总利润的计算公式，进而导出了计算合理井网密度和经济极限井网密度的公式，并对长庆油田的两个含油区块进行了实例计算。
The paper takes the whole process of oil field development as the period of economic evaluation. Acording to Sherkachef formula,the author calculates ultimate recovery of oil and associated gas ,thus to obtain the total production value and operation cost. Economic target such as tax payment,resource tax,commerciality ofmarketable crude oil,interest rate of fix investments are considered according to new tax regime. The author deduces the calculation formula of total profit vs. well density and the formula of rational well density and economic limited well density. Using this method,the author runs calculations of the rational well density and economic limited well density in regions W and Y of Changqing oil field.
