Abstract： In economic evaluation on natural gas reservoir， applied mainly are internal rate of return， net present value， investment payback period and other technical economic index to evaluate the development benefit. In development phase， gas reservoir exploration and productivity construction has been completed and operation costs will have direct effects on the economic benefit of gas reservoir development. Applied are basic principles of technical economy and established is a model for operation cost economic limit in combination with income and expenditure in gas reservoir development. Through this model， obtained are a set of relational data between operation cost economic limit， single well daily output， well depth and the price. Applied is the software SPSS for multivariate linear regression of these data and obtained is mathematical model of the relationship between operation cost economic limit， single well daily output， well depth and the price， which provides a simple method for calculation of operation cost economic limit in gas reservoir development.
