渗透性好的井压力恢复时,一般关井4天达到径向流。低渗井关井10天,仍有80%以上的井不出现径向流直线段。图版拟合解释资料时,此类数据多解性强,只能提供末点静压,影响压力资料的应用。本文应用安塞油田的等轴双曲线压力预测方法,进行适用性探讨。 When the well with good permeability resumes pressure, the radial flow is normally reached 4 days after the well is closed. Low-permeability wells shut-in 10 days, there are still more than 80% of wells do not appear radial flow straight section. Plate version of the interpretation of data, such data more than strong, can only provide the end point of static pressure, the impact of pressure data applications. In this paper, Ansai oilfield isometric hyperbolic pressure prediction method, the applicability of discussion.
