【摘要】 根据地层压力的预测理论和Eaton方法的原理,针对此方法中参数众多且获取困难的问题,主要分析了静水压力、上覆岩层压力和正常趋势线速度的获取问题。以东营地区为实验对象,采用Eaton方法预测该地区的地层压力。实测数据和预测数据对比结果表明,预测结果精度较高,能有效地指导现场钻井施工。更多还原

【Abstract】 According to the prediction theory of formation pressure and the principle of Eaton method,the problem of obtaining of the hydrostatic pressure,the overburden pressure and the normal trend line speed are analyzed in view of the many parameters and difficulties in this method.The Eaton method was used to predict the formation pressure in the Dongying area.The comparison between the measured data and the predicted data shows that the accuracy of the prediction results is high and can effectively guide the drilling construction.更多还原
