摘要
This paper studies the pore structure,two-phase fluid flow rule,starting pressure gradient and rock compression of the thin zone and lean reservoir by the physical simulation experiment. The result indicates that the pore structure and percolation characteristics of the thin zone and lean reservoir are very different from the middle and high permeability reservoirs.The starting pressure gradient and the pressure sensitivity have great influence on the thin zone and lean reservoir.Only the rational injector producer pressure difference and injector produce distance are chosen and the effective displacement pressure difference is established,the harmful influences of starting pressure gradient and pressure sensitivity can be overcome and the development effect can be improved.
