摘　　要：现有的电缆地层测试产能评价方法在测试参数设计方面对储层特征、流体类型等影响因素考虑较少，严重影响储层产能预测的可靠程度。从储层产能评价的基本原理出发，结合仪器自身的工作特点，针对高渗、中低渗、两相和稠油储层分别建立了探头直径及测试点数的优选原则、测试压差和流量安全计算模型，给出最短测试时间和取样时间的设计方法。提高了泵抽式电缆地层测试的工作制度设计水平，现场应用效果良好。The following influencing factors such as reservoir characteristics, fluid types and so on are seldom considered in current productivity evaluating method of wireline formation test, thus the reliability of the above prediction is seriously suffered. Starting from the basic principles of the evaluation, the optimized rules, testing pressure drawdown and the calculating model of the flow rate are respectively established for probe diameter and tested points by integrating the working characteristics of the instruments concerned in respect with high-permeability, middleand-low permeability, two-phase and heavy oil layers. Finally the designing method for the minimum test and sampling times are presented. All the achievements above enhance the design level of the working system for the formation test by pump-out wireline and moreover the practical application results are much better.
