Study On Recoverable Reserves Evaluation In Sabei Area

About recoverable reserves of calibration and calculation, The E&D Institute has been exploring and doing a lot of work, especially about water flooding, there are many methods, but we require preferably calibration method that can be adapted Sabei area of high water cut. The recoverable reserves estimates method of polymer flooding is still using laboratory experiments and numerical simulation results, but in the production, the eventual recovery is difference, because the reservoir properties of each block are differences. With the development of technologies, it is important to further improve the clear partition blocks, layered ultimate recovery system, which can be provided reliable geological basis to research the partition blocks reserve base, layered system.This paper studies Sabei development zone for determining two flooding recoverable reserves calculation method, the calculation model was established, using the model in the north zone of water at the end of2012, the block polymer flooding, and hierarchical system calculates the recoverable reserves, quantified the recoverable reserves north development zone; Water flooding is studied fine development demonstration area matching adjustment measures evaluation method, the basis of fine potentialities and the basis for the evaluation; The work for adjusting the salt solution and reason able formulation of Mr North development zone annual and long-term production and operation planning is of great significance, at the same time provide reliable material basis for determining fine exploration.
