Research on water driving state evaluation and adjustment technology based on streamline
Institute of Geology, the Third Oil Production Plant, Daqing Oilfield Company, Daqing 163113, China
The general reservoir engineering method is the injection volume and production between the regular injection-production well pattern (five-point method, seven-point method, nine-point method, etc.), geometric average calculation or kh method. The accuracy of the calculation results is low and it is difficult to reflect the political enemy dynamics of reservoir heterogeneity and correctly evaluate the water characteristics of reservoir development and characteristics. Problems of water injection, distribution and well efficiency are not solved. We can intuitively understand the dynamic flow characteristics of fluid in underground by using the oil-first device technology, and combined with the basic principles of reservoir engineering, a method of hydraulic reservoir dynamic evaluation is proposed. Using this method, many variables such as drainage area of oil well, flooding velocity, flooding swept area between oil Wells can be evaluated quantitatively, and the development effect of oil field can be evaluated accurately. According to the analysis of the characteristics and factors of the distribution of the wire, the corresponding adjustment measures are taken to make the dominant wire weaker and the weak wire stronger, and finally achieve the purpose of improving the recovery rate.
Key words: water drive evaluation / Streamline numerical simulation / Development adjustment
