标准化钻速法能较好地检测地层压力,但也存在不足。我们对这种方法进行了完善和简化,提出了修正标准化钻速检测地层压力的方法。实践表明,修正标准化钻速法检测地层压力具有精度高、对压力变化反应敏感和易随钻检测等特点。
The standard drilling method can detect the formation pressure well, but there are also some shortcomings. We have perfected and simplified this method and proposed a method to correct the normalized penetration rate to detect formation pressure. The practice shows that the correction of the normalized drilling velocity method for detecting formation pressure has the characteristics of high precision, sensitive to pressure changes and easy to detect while drilling.
