Study On Water-flooding Exploitation Technical Policy For Tight Oil Reservoir.of He Shui Zhuang230Wells Field

Our tight oil resources are wealthy.But tight oil exploration and development are late,especially the development of technology can not meet the requirements of large-scale industrial exploitation. Therefore,it is necessary to carry out research to improve the effectiveness of tight oil development. Based on the analysis of tight oil reservoir geological characteristics and development of dynamic characteristics of He shui Zhuang230well field.and through the research of geological modeling technology,reservoir engineering demonstration and numerical simulation,and finally proposing a reasonable and applicable injection technology policy development of He Shui Zhuang230well field.The main research results are:(1) using geological modeling techniques to complete the structure modeling, facies modeling and parametric modeling and coarsening the model and provide the basis model for the numerical simulation (2) assessing He shui Zhuang230well field development effect with dynamic reservoir data and researching the development of policy limits and finally obtaining the the development of policy limit indexs, such as reasonable development way, the pressure to maintain a reasonable level and reasonably well productivity.(3) fitting the development indicators such as original geological reserves of reservoir pressure, oil production and composite water content and researching the rational development of tight reservoir technology policy on the basis of the model to determine the rational development approach, well pattern research, flooding pressure, flooding-production ratio,formation pressure to maintain a reasonable level.It is important to improve the oil reservoir ultimate recovery and Economic efficiency. This paper is significant to improve tight oil reservoir production,and cost-effective development of tight oil reservoir,and realize long-term and stable development.
