摘　　要：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。Exactly determining the profile of formation caving pressure is most important for well bore stability and safe drilling. This paper founded calculation model of formation caving pressure and calculated formation caving pressure of this district by use of logging data of Zhongshi district in Jianghan Oilfield. Contrasting with the expanding rate of drilled well hole shows that the calculation model is correct and can be applied in field drilling of Zhongshi district in Jianghan Oilfield.
