Abstract: Abstract：The development projects of the less than 10 mD ultra-low permeability reservoir and those of more than an average
of 20 mD low permeability reservoir are very different. The lower the permeability is，the higher the start-up pressure there
is，so the development of technique and programme development are influenced. The results show that the results do not meet
the actual situation with the same starting pressure gradient. The results reflect more good ultra-low permeability reservoir
of the actual situation with the application of section starting pressure gradient. Space between wells has little impact on the
calculation of the pressure for higher permeability，but ultra-low permeability reservoir pressure are greatly influenced.
