Improvement Of Sabei Development Area And Three Kind Of Water Lfooding Injection Increase Technology Research

Three types of reservoir is the main reservoir and the two reservoir in Daqing oil fieldoutside of all layers in Sabei development area, three types of reservoir effective thickness ina river is less than1meters, a permeability of less than100×10^-3μ m in thin and poorreservoir and surface reservoir, geological reserves of about12530×104t, total SA northernhair geological reserves of20.44%. The current development of mainly water floodingdevelopment, two, three times water flooding exploitation object encryption key. But becauseof the sand body types include front sheet sand, and more layers, thin thickness, lowpermeability reservoir, the plane change, residual oil distribution is scattered, resulting inthree kind of water flooding is difficult to dig potential. Conventional measures of effect is notideal, restricted three reservoir exploitation.In order to solve the problem of three types of reservoirs, fully explore the potential ofresidual oil in different wells, remaining oil distribution features, study and formulate a set ofsuitable for three types of reservoir at present well pattern mining conditions of water drivedevelopment of increasing production and injection technique, the" control of the efficiencyand improvement of" three types of reservoir water flooding development effect have animportant and far-reaching significance.
