摘要
HH -2钻进式井壁取心器是在垂直井壁方向上获取岩芯的机电一体化设备 ,对全面了解岩心在地下的状态并进行油井开发起到了至关重要的作用。文章介绍了该仪器在三维空间确定岩心位置的基本原理 ,阐述了该仪器的主要技术指标。地面控制系统采用 80C5 5 2单片机 ,使控制功能加强 ,元器件减少 ,电路可靠性大大提高。该仪器不仅完成数据采集、控制及计算等 ,还可将计算结果 (方位和倾角 )以模拟量的方式输出。通过现场应用表明 ,收到了良好地应用效果。
HH-2 rotary sidewall coring tool is an electromechanical integrative equipment to obtain coring in the direction perpendicular to borehole wall. The coring tool is developed on the basis of HH-1 rotary sidewall coring tool,and an azimuthal measurement system is enhanced to realize three dimensional determination of core position. The tool core is single chip computer,and the system control is enhanced and reability is improved. The coring tool mainly finishes data acquisition,control,calculation,analog output. The thoery for three dimensional coring of HH-2 rotary sidewall coring tool and circuit disign are analyzed.
