低渗透油藏经济界限产量计算方法探讨

油藏经济界限产量研究是目前油田改变经营方式的主要依据。只有适时了解目前油田的经济产量界限，及时改变油田开采方式，才能提高油田整体经济效益。根据目前国内财税制度和低渗遣油田开发状况，提出了一种低渗透油田经济界限产量的计算方法。通过实例计算，具有可操作性。该方法对于国内其它低渗透油田经济界限产量的计算具有一定的借鉴意义。

An approach to calculation of economic limit rate for low permeability reservoir

Economic limit rate of a reservoir is the major basis of changing oilfield business scheme. Oilfield economic benefit can be improved only through timely comprehending of economic limit rate and changing of recovery method. In accordance with the current finance and taxation and development state of low permeability reservoir, a calculation method of economic limit rate for such reservoirs has been proposed. Case calculation shows that this method has operability. This is a reference for calculation of economic limit rate of other low permeability reservoirs.
