Research On Oil Well Production Characteristics And Developped Plan Of Shajiagou, In The Eastern Of Shanbei Slope

Based on the research and understanding of the basic geological features of Triassic Yanchang group Chang 6 oil group in Shajiagou area, eastern of Shanbei slope of Ordos Basin, the thesis analyzed the characteristics of production and development of this area from multiple angles such as development sequence, development methods, characteristics of formation pressure, capacity conditions, production performance, reservoir fracturing evaluation and so on, and studied the distribution of the remaining oil combined with the geological reserves calculations, and proposed effective development proposals to next production for the area.Ganguyi oil field Shajiagou area is typical of low porosity and low permeability reservoir, which mainly relys on natural energy to achieve production of industrial oil flow since there was oil production statistics in 1983. It shows characteristics of fell fast production and deficit formation pressure, and pressure is 0.3MPa only currently. Fracturing to reservoir is the main means of production and development, and fracturing has a relatively significantly increased yield to production of study area through the study of dynamic characteristics of production. Research area Chang 6 reservoir geological reserves is 620×104t, and recoverable reserves is 68.26×104t, and cumulative oil production 56.22×104t, and the remaining recoverable is 12.04×104t, and Chang 613 and Chang 612 small layer total remaining recoverable resources is 8.45×104t among these resources, which is the good intervals for development potential of remaining oil in this area.
