长庆油田三叠系油藏产量递减规律研究

运用数学方法与油藏动态相结合，对三叠系不同类型油藏的递减规律展开研究，建立了低渗油田双曲递减方程的渗流理论，并运用数学逐次逼近法判断递减类型，确定了三叠系不同类型油藏递减规律，制定了不同类型油藏产量递减规律图版，指出了影响递减的主要因素，为油田开发调整、综合研究及产量预测提供依据。

Production Decline law of the Triassic reservoir in Changqing Oilfield

Through combination of mathematical methods and reservoir performance, study production decline law of different types of Triassic reservoirs, a percolation theory of hyperbolic decline equation for low permeability Oiltleld was established. By application of mathematical successive approximation law to judge decline type, identified different types of Triassic reservoir decline laws formulated different types of maps reservoir production decline, pointing out that the main factors affecting the decline, adjusted for oilfield development, research and production forecasts consolidated basis.
