The effective permeability can be regarded as the average permeability over the whole production zone influenced by the fluid flow during the well test. 由试井解释得到的有效渗透率,可以认为是油层在测试过程中流动影响所涉及的整个范围内的渗透率的平均值。
The design of location and size of over flow well, and reasons which resulting in the defects such as flow mark near the gate, melt burned and gas leaking from the gas entrance are analyzed, and the solving measures are put forward. 对溢料井的位置和尺寸的设计,以及浇口处流痕、熔料烧焦和气嘴漏气等成型缺陷产生的原因作了分析,并提出了解决措施。
