摘　　要：通过油藏工程计算，研究了注水开发中无因次采油指数和溶解气驱时无因次产油量的变化及影响因素，对中原油田老井自然递减因素进行分析，提出了减缓自然递减的建议。The author studies the changes and influence factors of dimensionless prodctivity index in waterflood development and dimensionless oil production in dissoved gas drive by the calculation of reservoir engineering. The influence factors of natural decline of old well in Zhongyuan Oidfield are analyzed,and the proposal to reduce natural decline is given at last.
