基于电缆地层测试资料储层有效渗透率计算方法研究
|
摘要
电缆地层测试资料能够提供地层冲洗带单点的流度,流度是DST测试外最优的储层渗流特征参数。然而测压流度与DST测试渗透率往往不匹配,影响储层产能评价和下一步作业的决策。为此,在电缆地层测试资料流型判断及流度计算的基础上,选取同时存在球形流流动及径向流流动的样本点,利用球形流流度分别建立了油气在2种模式下的视径向流计算方法,实现了对于径向流流型不存在的测压点视径向流流度的求取。最后将求取的径向流流度经过区域相渗资料以及流体黏度处理,得到有效渗透率计算公式,实现了由测压流度到地层有效渗透率的转化。实际应用结果表明利用测压资料换算得到的气相有效渗透率与试井渗透率符合良好,在不同渗透性地层均取得了较好的应用效果。
The wireline formation tester data can provide a single point mobility of flushing zone, and so it is the best reservoir percolation characteristic parameter besides DST. However, the pressure mobility and DST permeability often do not match, affecting the reservoir productivity evaluation and decision-making for the next operation. Based on the pressure flow pattern judgement and mobility calculation of wireline formation tester, the pressure test points both with spherical flow and radial flow are selected, using spherical flow mobility to establish the radial flow mobility calculation method of oil and gas mode respectively to solve the problem for obtaining the pre-radial flow mobility with no appearance of actual radial flow. Finally the effective permeability calculation formula is obtained by the calculated radial flow mobility processed through the regional infiltration data and fluid viscosity, which realizes the transformation of pressure mobility to the formation effective permeability. The results of practical application show that the effective permeability of gas phase obtained from pressure measurement data is in good agreement with DST permeability, and has achieved good application results in different permeable formations.
