Abstract: The digitalized model of economic evaluation uses digital information technology like big data and cloud computing to construct the digitalized management system of “three-level operational system”. The model is established in the efforts to formulate the systematic process, create the integrated databank of economic evaluation, develop the software platform for oilfield economic evaluation and construct a number of digitalized modules for economic evaluation of reserves, evaluation of productivity construction and development plans, evaluation of single-well performance, evaluation of treatment results from ineffective wells, and evaluation of benefits from the treatment measures. The oilfield digitalized performance-managing model covers the whole life cycle of the oilfield, focusing on “management of the whole process, analysis of all elements and all-around evaluation”. Liaohe Oilfield uses the digitalized model to eliminate the hurdles among the cross-disciplinary data, increase and invigorate the economic reserve assets, optimize the productivity construction projects, and evaluate the feasibility of development plans. Good results have been achieved in evaluation of single-well performance and treatment of ineffective wells. The performance-based yield was boosted 5.2 percent as compared to the previous year, while the marginal benefit yield and ineffective yield declined 3.3 percent and 1.8 percent separately. The structure of performance-based yield was remarkable for optimization. In addition, the profit-making and performance-controlling abilities of the oilfield were effectively improved, thus fueling high-quality development of the oilfield.
