设计了一种监测钻井参数的实时软件系统。这种软件系统采用汇编语言,并启用8087(或80287)数值处理器,用汉字显示,便于数据监测与采集,钻井动态数据可直接存储在磁盘上,随时监测钻井工况。现场使用证明,该程序能满足钻井工程需要。文中论述了软件系统的功能设计原理,分析了钻井参数的变化情况及确定方法,介绍了数据转换模块的特点。 A real-time software system for monitoring drilling parameters was designed. This software system uses assembly language and enables the 8087 (or 80287) numerical processor to be displayed in Chinese characters for data monitoring and acquisition. Drilling dynamic data can be stored directly on the disk to monitor drilling conditions at any time. Field use proved that the program can meet the drilling needs. In this paper, the functional design principle of software system is discussed. The variation of drilling parameters and the determination method are analyzed. The characteristics of data conversion module are introduced.
