Abstract: Oilfield development process is a continuous potential-tapping process accompanied with a large amount of investment. Whether investment is economically effective and recovered in the expected period is an issue concerned by reservoir and economic workers and by development decision-makers in particular. To improve fund application rate and strengthen management of development investment, SINOPEC Zhongyuan Oilfield Company made the study of single-well economic optimization on the basis of its original economic assessment. Based on comparison and selection of new well economic assessment methods of oil fields both at home and abroad, the company came up with a set of methods for economic performance assessment of new well and single well and economic boundary assessment. It also independently developed single-well economic assessment software, providing the quantitative data for making decisions on investment for new wells. Based on software application, the plans for 284 new wells of this oilfield were brought under appraisal on their economic feasibility. Atotal of 10 low-efficiency wells were excluded while other 39 low-efficiency wells were optimized for thier design plans, reducing the investment scale.Theamount offund saved from investment for low-efficiencydevelopmentwas accumulatedto 95.19million yuan.
