摘 要:在油气田开发生产过程中,加密调整井边际效益变化规律遵循加密井边际产量递减规律、加密井边际成本变化规律和加密井效益变化规律。随着油田开发程度的加深,资源劣化加剧,加密调整井增产及增加可呆储量的效果不断变差,边际成本不断上升。应用这一规律,可对油气生产过程加以控制,确定合理井网密度和单井增油界限,提高油气田开发经济效益。In the process of oil and gas field development, the changing laws of infill-adjusting well marginal efficiency follows the laws of its marginal production decline, marginal cost changing and efficiency changing. With the increase of oilfield development, oil resources are getting poor, the effect of infill-adjusting well production increase and increase of recoverable reserves are becoming poor, marginal cost continuously rises. The laws could be used to control oil and gas production process, establish rational well pattern spacing and single-well oil increase limit as well as to raise economic efficiencies of oil and gas field development.
