油田开发综合含水经济极限研究

A STUDY ON THE ECONOMIC LIMITS FOR COMPOSITE WATER CUT IN OIL FIELD DEVELOPMENT

在社会主义市场经济体制下的油田开发，要研究其经济规律，提高开发经济效益。油田开发综合含水经济极限的研究，就是试图解决油田进入中高含水开发期后的经济界限问题。作者采用注采平衡的开发原理和投入产出的经济原理，推导出经济极限含水单井模型，进行了实例计算，得到了油田在中高含水的条件下开发是有经济效益的结论。

Economic regularities in the oil field development under marketing economic condition in a socialism system should be studied for its economic profit. A study on the economic limits for composite water cut is carried for the economic profit of oil field development by the determination of the economic limits of composite water cut in the middle-later stage of oil field development. By an application off the balancing of water injection and oil producing as well as the input-output theory in economics, the author derived a model of economic limits of water cut for a single well. An actual example is presented in this paper and a conclusion is arrived that economic profit will be obtained in the development of an oil field under middle-high water cut stage.
