摘要
介绍了旋转式井壁取心系统的组成及其工作原理。针对旋转式井壁取心仪器,设计了地面控制软件,该软件可实时跟踪伽马或0.4 m电极曲线,准确定位取心位置,同时采用时间驱动记录取心过程中泵压等参数。分析了软件中取心深度定位、深度驱动与时间驱动交替运行、网络通讯、双缓冲绘图等关键技术的具体实现。2009年在任91井的实际应用表明,该软件的准确性和实时性达到了旋转式井壁取心系统的功能要求,运行稳定可靠。
Introduced are the system composition and working principle of rotary sidewall coring tool. Designed is a kind of surface controlling software for the rotary sidewall coring tool, which can track GR or 0. 4 m electrode in real time, locate core points accurately, and record pump pressure and other parameters during coring operation through time-driven approach. Analyzed are the realization of key technologies, such as coring depth location, alternative operation of depth drive and time drive, network communication and double buffering cartography. Practical application in Ren91 well in 2009 shows that its accuracy and instantaneity reach up to the designed demand and its operation is stable and reliable.
