Description
technical field [0001] The invention relates to the technical field of PDC drill bits, in particular to a self-adjustable PDC drill bit. Background technique [0002] As we all know, PDC bit is an important tool for oil drilling on land and sea for China National Petroleum Corporation, China Petrochemical Corporation, and China National Offshore Oil Corporation. It is a high-tech product introduced by my country at the end of the last century. It is used for drilling in homogeneous soft to medium hard formations. It has the advantages of fast speed, long life, and low cost per unit footage. [0003] However, during the drilling process of today's PDC, due to the possibility of drilling into some relatively hard materials, the drilling position of the drill bit is slightly deflected, and only this slight deflection, after a long period of drilling, will make the The drilling angle changes greatly, but it is difficult for the staff on the ground to know the working status of ...
