老油田高含水期可采储量及增产措施经济评价方法

注水开发油田依据含水高低和产油量的变化趋势可以划分为若干个阶段,为了取得注水开发油田比较好的经济效益,就要依据油田各阶段的特点,研究重大调整措施的效果和做好经济评价分析,对其影响经济效益的主要因素采取相应的对策。本文着眼于注水开发油田高含水期可采储量及增产措施经济评价方法的研究,主要阐述了井网加密调整经济分析、经济可采储量和增产措施经济产量计算方法。经过多年来的实践,虽然对经济可采储量及增产措施经济评价方法较 多,但本文所阐述的方法是较为广泛应用且切合实际的方法。

THE ECONOMIC EVALUATION METHOD OF RECOVERABLE RESERVES AND STIMULATION MEASURES IN HIGH WATER-CUT MATURING FIELD

Water flooding reserve can be classified into different stages according to water cut and oil production variations.To pursue more benefits from water flooding reserve,it is necessary to analyze the important adjusting measures and make correct economic evaluation in accordance with characters of different stages so as to take measures in response to the main influence factors.This paper mainly analyses the recoverable reserves of high water-cut stage and economic evaluation methods of well stimulation, expounds the economic analysis of pattern encryption adjustment and introduces the calculating methods of economic recoverable reserves and economic production of well stimulation.Through many years′practice,there have been a lot of evaluation methods of economic recoverable reserves and well stimulation,but this paper introduces a method which is closer to reality.
