Study On Deep Profile Control And Flooding Technology In Jinhai Oilfield

The main problem of Jinhai oil production plant of Hainan three block now faces: the reservoir exploitation degree is high,the existing condition adjustment is difficult;the reservoir heterogeneity is serious,the water drive degree difference;high pressure injection.The above problems seriously restrict the normal exploitation of the block,and there are some remaining recoverable reserves in the block,we take measures to exploit the recoverable reserves and improve the recovery of the block.In this paper,through the analysis of the geological characteristics of the block,the systematic evaluation of the effect of the development of the system can be carried out on the depth of the block adjustment technology.First we on this block of residual oil potential and distribution were analyzed using the dynamic analysis method and numerical simulation method,analysis data by the geological conditions and the current mining method,the deep profile control technology can be implemented in this area.According to the comparison of the gel system of two kinds of drugs in laboratory,it is suggested that the phenolic resin gel system composed of low molecular weight polymer is recommended.Through the analysis of the advantages and disadvantages of the common chemical adding device and the comparison of field test data,the reasonable scheme of optimizing the dosing device is selected.According to the characteristics of the block,the two groups of oil wells in the 23-13 block are optimized to carry out the displacement experiment,and the corresponding operating parameters and the testing scheme are worked out.
