Study On Remaining Oil Distribution And Potential Exploitation Of High Water - Cut Reservoir In

Currently, most of oil fields in our country has been in the high water cut stage, in this stage,the research of remaining oil distribution with has high water content of the continental distribution of water flooding of oil reservoirs,Ultimate goal is to develop the fundamental work is the implementation of tapping the potential measures to improve the recovery of the foundation. Accurate picture of remaining oil reserves and its sub-Distribution range, the adjustment for the oil field, tap the potential to improve the ultimate recovery is of great significance.This in-depth research remaining oil distribution of domestic and international literature on the basis of theory and to the next group of six grams in the area of the reservoir is a high water cut Study in order to drive high-water sandstone reservoir of water distribution and tapping the potential of remaining oil research at the core, based on the high water reservoir performance Analysis, reservoir engineering and reservoir simulation detailed comprehensive study to establish the adaptation of water flooding in high water cut oil field development of the reservoir sandstone Evaluation system for the amount spent and remaining oil potential of comprehensive evaluation system; in the remaining oil distribution based on the area for six Proposed a high-water reservoir characteristics to adjust the design principles of tapping the potential and technical programs.Firstly, the use of reservoir permeability saturation curve according to the nature and water content obtained oil wells in oil saturation region, the anti-plane Reflected the distribution of remaining oil; use of profiles to statistics produced liquid water and a small layer of each use of the degree of its vertical indirect Reflects the distribution of remaining oil; through the production of data analysis and evaluation rank correlation coefficient between two methods of connectivity made wellEvaluation, the residual oil distribution reflects the changes of history; then use the numerical simulation accurately describe the distribution of residual oil Situation; Finally, tapping the potential adjustment measures were demonstrated.
