摘要:
要:渗透率低于 10 mD 的特低渗储层与平均渗透率大于 20 mD 的低渗储层开发技术政策界限和开发方案制定等
有很大的差别,渗透率越低,其启动压力成倍增加,这就影响了开发技术和方案的制定。应用分段启动压力梯度进行
分段计算并进行对比,计算结果表明:用同一启动压力梯度计算的结果不符合实际情况,而应用分段启动压力梯度计
算的结果更能很好地反映特低渗储层的实际情况;井距对较高渗透率的驱动压力计算影响并不大,但对于特低渗储层
的驱动压力计算则影响很大。

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.
