利用短期关井压力数据确定地层压力

DEFINING FORMATION PRESSURE IN SHORT-TERM CLOSED-IN PRESSURE PARAMETER

    摘要
  • 摘要: 地层压力是油田勘探开发中一项必不可少的基础参数。目前,确定地层压力的方法较多,但它们通常都是利用较长时间的关井压力数据来求取地层压力。通过分形油藏压力不稳定试井理论的研究,提出了一种使用短期关井压力数据确定地层压力的新方法。实践证明,这种方法与常规的Horner法相比,精度相同、方法简便、适用范围广,具有广泛的实用价值。

     

    Abstract: Formation pressure is an indispensable parameterfor oilfield. Now, a lot of methods can define formation pressure, but they usually based on parameter of long-term closed-in pressure. In this paper, a new method is presented to define formation pressure in short-term closed-in pressure, which based on the research about theory of unstable well testing of fractal reservoirs. To compare the normal method of Horner, this kind of method is accurate, quick, wide and useful.
