The Technical Limit And The Development Index Varying Tendency At The Period Of The Highest Water Cut Stage In Lasaxing Oilfield

This paper is aimed at existing two issues in development index, from the most common type and xipaqiefu curve ,dynamic method which calculates geological reserve has been amended according to reservoir engineering ,but also,the problem about calculating the geological reserve of classified well is resolved ,laying the foundation for analysis and prediction of classified well.Development index anf pedicted model is established by waterflooding curve decomposing and composing under measure condition,which improve predicted accuracy.The characteristic of the highest water cut stage of Lasaxing oilfield is analyzed comparing to the characteristic of development at home or abroad oilfield.Classified critria of the stage of oilfield development is given out.,and will be the basis for all Lasaxing oil development block, all levels of the Department of Well into the development phase, analysis phase of the development trend of the development indicators are given at different stages of development of various types of wells and the technical boundaries of blocks. The strategy was put forward aiming at the development phase of the characteristics of Lasaxing oilfields..
