| 摘 要： | 在对海上油田进行油气资源评价时,使用泵抽式电缆地层测试能快速获得储层的渗透率,节约大量的测试成本,降低作业风险.从渗流力学的基础理论出发,在充分考虑测试流量非稳定性和地层渗透率非均质性的前提下,建立了非稳态非均质球形流渗透率解释模型,并开发出基于渗透率正演压力原理的试井数值计算方法,能够提高电缆地层测试渗透率解释结果的可靠性和计算精度,同时满足现场在线解释的实时性要求.研究成果在一种新型泵抽式电缆地层测试器(ERCT)的测试资料解释中得到了验证.

| Abstract: | Due to the low cost and risk,pumping cable formation permeability tester is widely us ed for the evaluation of oil and gas resources in off-shore oilfields.Considering the instability of test flow-rate and the heterogeneity of formation permeability,a spherical unsteady heterogeneous flow permeability interpretation model is derived from the basic principles of fluid mechanics in porous media,and a numerical well testing algorithm based on the permeability forward-modeling pressure principle is put forward ... |
