在综合应用多种理论技术和多学科交叉的基础上编制了一个井漏处理系统应用软件。该软件采用系统模拟分析技术, 通过建立渗漏问题多相流方程的数值计算模型和裂缝在流体压力作用下张开延伸的PK 与PKN 模型, 实现了渗漏和裂缝漏失的动态模拟计算。其功能包括钻井井漏设计、现场处理分析和完钻数据处理, 具有效率高、精度好、适应性强等优点,并在中原油田得到了初步应用。该软件采用Pow er Bu ilder 语言开发, 同时具备数据库管理和工程设计计算能力, 结合模块化设计方法、菜单驱动和多文档管理窗口技术, 并将处理结果以文本文件、各类数据库和图形等多种形式输出或打印, 使用十分方便。

Th is paper reports a successful well loss systematic software by in tegrated use of various theories and technologies. This software uses system simulation and system analysis technology to establish numerical model of porous multiphase flow in permeable formation well loss problem and fracture well loss PK or PKN model, finally well loss dynamic simulation has been realized. Its function includes well loss density prediction, drilling site well loss characteristics estimation, off-line drilling data processing at the advantage of high efficiency, good precision and better adaptability. It has been designed by Power Builder language, therefore it provides routine data administration and engineering design capabilities, having the characteristics of using conveniently after integrating modularization design method, menudrive, MDI technology, and various output or print types under textfile, database, and graphics.
