Abstract:

Starting pressure gradient does not truly exist，which is a wrong phenomen0n in exDeriment．Through theanalysis of some mistakes caused by starting pressure gradient，this paper proved that the starting pressure gradient d0es not exist·With starting pressure gradient，pressure can increase automatically without any liquid injection；the e will be n0unique equilibrium pressure in reservoir，but a pressure distribution with a pressure gradient；reserv0ir Pressure can not return to initial value even after a long time；reservoir pressure distribution will evolve a singularity point mathematica11v：migration of oil and gas can not make progress and accumulation of oil and gas can not take place at all；static liquid will have the ability to suffer from shear stress． All the phenomena above do not agree with the Dractice 0f 0it and gas development，and also do not comply with the principle of science． Without starting pressure adient，the science 0f petroleum will be self-consistent．
