摘要
本文给出了分析模型并对多探头地层测试器测得的压力瞬时值加以解释。多探头测试器有3个探头。伸入探头从地层中吸入流体并产生一个脉冲。所产生的压力响应由伸入探头和两个观测探头测量。一个观测探头位于伸入探头对面,其水平高度和伸入探头相同;另一个观测探头在垂直方向上和伸入探头相隔一定距离但位于同一方位角上。文中讨论了储层各参数对压力响应的影响,通过实例说明了模型的应用。
Xiao Zhongyun. Permeability Determination with a Multiprobe Formation Tester. WLT, 1993.17 (5): 332～337 This paper presents analytic models to interpret the pressure transients measured by a multiprobe formation tester. The multiprobe tester discussed consists of three probes. The sink probe generates a pressure pulse by withdrawing fluid from the formation while the resulting pressure response is measured at the sink probe and at each of two observation probes. One observation probe is positioned on the opposite side of the borehole on the same vertical plane as the sink, and the other is displaced vertically on the same azimuthal plane as the sink. The effect of the various reservoir parameters on the pressure response is discussed. Application of the models is demonstrated through an actual field example.
