摘　　要：针对即将进入高含水期的D油田东河砂岩组油藏,应用油藏工程、数值模拟和矿场统计等方法研究了影响产量递减的主要因素及其变化规律。结果表明:D油田东河油层组的产量递减规律呈指数型递减;影响递减率的主要因素是含水上升率,其次是采液速度;影响初始递减率的主要因素是稳产期末的相关指标。研究成果对油田动态分析和开发调整具有一定的指导意义。In the light of Donghe sandstone group reservoirs entering into high water cut period in the near future in D Oilfield, with the help of the following methods such as reservoir engineering, numerical simulation, field statis- tics and so on, the main factors and their changed laws for influencing the production decline are studied. The re- suits show that the laws of the production decline are accordant to the type of the exponential decline; and the main factor of influencing the decline rate is the rise of the water cut, followed by the liquid production rate ; and further- more the principal factors of influencing the initial decline rate are the relevant indices at the end of stable produc- tion period. The research results achieved above possess a certain guiding significances for the performance analyses and development adjustment of the oilfield.
