Economic Evaluation And Research Of Daqing Oilfield Polymer Flooding

Under present market economic situation, economic evaluation of the development technique for oilfield is becoming more and more important. How to calculate with polymer flooding? How to analyze and account the investment and cost? In order to appraising the program accurately and completely, How to select the proper parameters and methods in the process of evaluating? How to carry on the economic analysis to the program? This article will discuss the above-mentioned issues, and try to establish the basic frame of solving these issues.The result calculation of development project is the base for the economic assessment. Polymer flooding evaluation start from its production behavior, the methods and simulation parameters of polymer flooding performance are determined. The character of cost efficiency is analyzed and the process of polymer flooding economic factor. The economic board-line of single well and comprehensive water cut, the alert point of oil marginal cost and per ton cost and economic production are studied.Polymer flooding evaluation state firstly economic assessment index and also calculation method of effective index. On the base of two results with polymer flooding and water flooding, five evaluation methods are investigated. The cost conventional and after measure parameters are presented.In the practical application, above will analyze and the discussion method applies north the Daqing Oil Field west three areas in the polymer development zone technology economic evaluation, has obtained the concrete appraisal result and the benefit analysis result.In brief, in this paper, a set of basic framework for analysis and research of oil development economic evaluation is established through discussion and research of oil production calculation, polymer flooding technical and economic analysis. It is very meaningful for the large-scale application of polymer flooding.
