面向对象的测井仪器动态库设计

Design of Objectoriented Logging Instrument′s DLL

测井仪器有不同的种类,使用的测量原理、刻度方法和测量手段也各不相同。在不改动系统软件的前提下,要求测井地面系统能方便快捷地配接各种测井仪器。动态链接库技术是按照一定规范和接口约定,编写一种新的测井仪器操作库,动态安装到测井系统中,增强了可复用性、可维护性,达到动态添加新仪器的目的。

There are kinds of logging instruments with di ff erent principles,calibrations and measuring methods which are being continuousl y improved, so, the surface logging system should be easily implanted with all k inds of downhole instruments without modifying their software. Introduced is DL L(Dynamic Link Library) technology. A new logging instrument operating library w hich is installed into well logging system dynamically has been developed accord ing to some standards and interface criteria. So the reusability and maintenance of the system is enhanced. The system meets the requirements so that the new DD L is conveniently implanted to the instruments dynamically.
