地层坍塌压力剖面的准确确定，对于井眼稳定和安全钻井至关重要，本文建立了地层坍塌压力的计算模型，并利用江汉油田钟市地区的测井资料连续地计算了该地区的地层坍塌压力，与已钻井井径扩大率的对比分析表明，计算模型正确，能应用于江汉油田钟市地区的实际钻井中。
Accurately determining the formation collapse pressure profile is crucial to wellbore stability and safe drilling. This paper establishes a calculation model of formation collapse pressure and calculates the formation collapse pressure continuously using the logging data of Zhongshi area of Jianghan Oilfield , And compared with the well diameter expansion rate has been drilling analysis shows that the calculation model is correct and can be used in Jianghan Oil Field Bell drilling in the actual area.
