Method and device for obtaining state of oil well collapse

The invention provides a method and device for obtaining the state of oil well collapse. The method includes the steps that fluid injecting well mouth pressure of an oil well is obtained; whether or not the fluid injecting well mouth pressure and fluid injecting time meet preset conditions is judged, wherein fluid injecting time is smaller than or equal to fluid injecting stopping time; if the fluid injecting well mouth pressure and the fluid injecting time meet preset conditions, it is determined that an oil well is in the state of collapse. Through the method and device for obtaining the state of oil well collapse, the efficiency of obtaining the state of oil well collapse is improved. 本发明提供种油井垮塌状态的获取方法及装置，该方法包括：获取油井的注流体井口压力；判断注流体井口压力和注流体时间是否满足预设条件，其中，注流体时间小于等于注流体终止时间；若注流体井口压力和注流体时间满足预设条件，则确定油井为垮塌状态。本发明油井垮塌状态的获取方法及装置，提高了油井垮塌状态的获取效率。
