| 摘 要： | 利用电缆地层测试预测试压降数据进行渗透率解释，能够快速获得储层参数，为下步正式测试工作提供参考。对于大排量电缆地层测试器，在较薄储层测试时，压力很快传播到储层上下不渗透边界，流体的流动形态也从球形流动过渡到圆柱形流动，而目前还没有针对电缆地层测试的球形流一柱形流复合流动压降解释模型。为了通过电缆地层测试压降数据快速获得可靠渗透率参数，指导进一步的精确测试参数选取。应用渗流力学理论和方法，建立了电缆地层测试球形流一柱形流复合流动压降解释模型，利用该模型，可以提高薄层测试时压降渗透率的解释精度。

| Abstract: | Formation pressure drop data acquired by WFT were used for permeability interpretation and for rapid obtaining reservoir parameters and providing reference to testing operation.For displacement wire-line formation testers operating in thinner reservoirs,pressure was quickly transferred reservoirs without permeable boundaries,flow types were transformed from a spherical type to cylindrical type,but there was no model for interpreting the composite flow.To solve this problem,new interpreting model is established for spherical-cylindrical composite flow of WFT with high displacement,and it can improve permeability precision for WFT interpretation. |
