摘　　要：以新疆油田分公司老油田为例,从谢尔卡乔夫公式入手,结合经济评价期的研究,推导出计算老油田经济极限井网密度和老油田最优经济井网密度计算方法。该方法对老油田井网加密,特别是高含水期老油田零星井加密具有较强的实用性,使用该方法可使决策者最大程度地规避开发投资的风险。This study takes old oilfields of PetroChina Xinjiang Oil as examples,begins with Cierkaqov's equation,relates to analysis of economic appraisal stage,gives computations for well spacing density at economical limit and opti-mal economic spacing density of an old oilfield.This method is practical implications for infill development of old fields,particularly to sporadic infill drilling of old fields with high water cut.This method allows decision maker to avoid risk from exploitation investment in a great extent.
