Oilfield block development assessment, yield prediction and pre-warning are now the hot topics in the field of oilfield development. Building a monitoring indicator system is the first step to achieve this. We addressed the problem of the lack of single well production data by using the SPSS (Statistical Product and Service Solutions) Missing Value Analysis and cubic spline interpolation. The equation for calculating weights was improved and the missing values were filled based on interpolation. The oilfield block monitoring indicators were characterized by using different techniques for single well production monitoring. The former included water absorbing capacity, oil production capacity, fluid producing capacity, seepage capacity, and pressure-maintaining capacity. The latter included water injection profile, production profile, well log interpretation and pressure monitoring. Finally, a case study was performed on fault block reservoir III in No.1 district of GD oilfield. The degree of correlation between each monitoring indicator and oilfield block development indicators was calculated so as to verify the monitoring indicator system of oilfield blocks.Keywords
