Research On Production Dynamic Logging Evaluation In Geng X Reservoir

In the process of oilfield development,the analysis of the dynamic parameters of reservoir can obtain a series of very important information.Now through the production of dynamic logging we can know dynamic parameters in the process of water injection or liquid production and the failure conditions in the borehole.Mostly there are many complex situations in formations,coupled with the unceasing changes of hydrocarbon reservoir in development process,therefore we need to analyze the change of formation in many ways.Due to the continuous water flooding,the water cut in the formation become complicated,we must make effective comprehensive adjustment measures,to guarantee the efficient oilfield stable production.And dynamic production logging is by understanding the two section,to determine the change of reservoir parameters on the longitudinal characteristics,thus to provide evidence for oil recovery schemes,injection allocation scheme.In the actual process of oilfield development,dynamic production logging must be combined with well test and separate injection wells for studying oilfield.Using temperature,fluid density,pressure and magnetic positioning to determine the water absorbing layer,reservoir properties,dynamic parameter and equipment location.According to the above content,first of all,this paper studies the technology of oil and gas well testing,and the dynamic logging and separate injection Wells production deployment of technology.Pressure is analyzed by the nature of the well itself,the influence of the injected fluid and injection solution;Summarizes the principle of a variety of injection profile logging and interpretation;Sums up the advantages and disadvantages of each kind of water injection allocation method.Through the study on the actual production of the block data processing,using pressure buildup curve and pressure curve chart to determine various dynamic parameters of the reservoir;Through injection profile data processing,combined with the different way of water injection,the relevant methods for improving water flooding effect;Again to separate injection well prepared for statistical processing,it is concluded that more effective water injection scheme.Research shows: through pay attention to the adjustment of injection profile,increase the layered water injection,and improve the stress condition,can effectively solve the contradiction between the layers,improve the accuracy of water injection,and improve the level of formation pressure,finally able to achieve long-term stable yield,improve the recovery efficiency of security.
