在钻井现场使用新型PDC钻头前要对其特征(包括布齿特征、结构特征、技术特征和适应性特征)进行分析,为优选作好准备;利用电测声波曲线和自然伽马曲线,是一种较为科学的优选PDC钻头的方法;使用新型PDC钻头要注意以下事项:钻头选用与水利设计、钻前准备、下钻、井底造型、钻进试验与钻进、起钻。 The features (including cloth teeth, structural features, technical characteristics and adaptability characteristics) should be analyzed and optimized for use prior to the use of the new PDC bit at the drilling site. Using the electrical sounding and natural gamma curves is a A more scientific way to optimize the PDC bit; the use of the new PDC bit should pay attention to the following matters: bit selection and water conservancy design, preparation before drilling, drilling, bottom modeling, drilling test drilling and drilling.
