Domestic low- permeability oil rich in oil reserves . It is estimated permeability of less than 50 × 10 -3 μm 2 of non- heavy oil reserves in low permeability unused unused reserves of the country's total 40 percent or more. Efficient development of low permeability reservoirs in maintaining our growing energy needs is important. In this thesis, Pakistan 19 block development status , the use of theoretical calculations, numerical reservoir simulation technology combined with the method, a target reservoir numerical model to analyze the residual oil after water flooding distribution , design development of the next step of the target block adjustment programs. Analysis of the geological characteristics Ba19 block and development overview summarizes the current main difficulties encountered in the development and problems ; through fine geological modeling software , the establishment of three-dimensional Ba19 block fine geological model , the model fitting analysis through reserves reasonable. Using the Eclipse reservoir simulation software , to establish a numerical model of the target block reservoir , preferably reservoir properties , rock - fluid properties and other parameters , the fit of the target block 10 years of production history ( pressure , moisture , liquids production injection profile , etc. ) , evaluated the quality of history matching . The results show that after a decade of Ba19 block to develop , water utilization, development effect gradually worse ; Pakistan 19 block heterogeneity serious small layer of each level and remaining reserves mined vary greatly , which II5 layer and II3 reserves the highest level , the next step is to focus on the development of the horizon ; remaining oil distribution is mainly affected by structural highs , faults corner area, reservoir edge , the potential impact of residual oil zones . Numerical simulation results show that the block through the fill hole Ba 19 , adjustment wells drilled , extract , water shutoff profile series of adjustment measures , can effectively improve recovery , in which the II3 and II4 drilled wells fill reservoir Kong extracts measures best results.
