| Due to fault-block developmental, complex and heterogeneous serious,the complicated fault-block oilfield often showed the obvious contradiction between layers during the development process,which needs to continue to take measures to adjust in order to ensure stable productivity.In-depth research of the relevant literature for the development of complex fault block oil reservoir characteristics and the residual oil distribution, then systematic analysis the energy to maintain of Gao6 fault block, output variation, water drive conditions, and so on, Using a variety of method to evaluate the water drive position, predict recovery, and the extent through the use of reserves, Degree of well control, water flooding control, oil production rate and water rate increase parameters of the analysis, development of oil fields to make the evaluation results.Actual data collection of Gaoji oilfield, use the reservoir engineering and imulation method of combining study the development of complex fault blocks the effect of various factors, geological factors, including heterogeneity, sedimentary facies, micro- structure, reservoir rock and fluid properties, porosity and permeability structure, oil-water viscosity ratio, reservoir rock wettability, etc.; reservoir engineering factors, including the direction of water injection efficiency, well density and stratification exploitation; the injection process parameters of the water injection pump efficiency and speed of development effectiveness is relatively obvious.Well detailed study of a complete deployment of strata subdivision development, horizontal well technology, high angle directional wells, acid fracturing, water injection and other technologies in the Gao6 fault block, the development effect of the block to improve the feasibility, summarized the various technology to improve the complexity of the role of fault block reservoir development and the application development stage.
