PARAMETER OPTIMIZATION OF FORMATION PRODUCTIVITY TEST BY PUMP-OUT WIRELINE
摘要
Abstract
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, middle-and-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.关键词
