Benefit Optimization Analysis Of Increasing Production Measures In Oilfield

It is necessary to implement oilfield stimulation in the mid and late period of the oilfield exploitation. In recent years, with the continuous development of oilfield, there are many consequences that the major oilfield have to accept as the high degree of oil extraction, the sharp increase of water content, the small thickness and the low level of the abundance of the remaining recoverable reserves, the relatively low abundance of new replacement, and the decrease of the interests of oilfield. So how to find a job time to implement measures to increase production and how rational allocation of measures, how to improve efficiency and effectiveness of oilfield stimulation and how to get greater interests under the pressure of deteriorating geological conditions and funding tight become the major problem which major oilfield companies have to face. So studying on benefit optimization research is imperative to oil.Based on the analysis of the development procedures of oilfield and the development status in mid and late period, the implement of oilfield stimulation was Summarized indicated firstly, and the main problems about implement of oilfield stimulation and implement production and operation timing analysis and oil analysis and yield measures were summarized in the paper. Secondly, the current oilfield stimulation was briefly explained, and the shortcomings of the traditional evaluation methods were pointed by analyzing the traditional evaluation methods of the effect of oilfield stimulation. According to the different optimization method, the yield increasing measures can be divided into the single well stimulation plan and the optimization of the production plan of the oilfield.. As a result, DEA was introduced into evaluating on the effect of single well stimulation and then evaluation index system and evaluation model were established, and select some oil in an oil well has carried on the case analysis, the evaluation results. Finally, this paper standing in the oil or the entire block measures legitimization point of view,target profit for the purpose of the maximum establish oilfield stimulation optimization model, selection of an oilfield carried out to illustrate the application of optimization model of stimulation measures, and gives obscurity measures recommended optimization. The final conclusion of this paper.
