Abstract

The invention provides a drilling directional angular difference measuring device. The drilling directional angular difference measuring device comprises an upper slip assembly, a lower slip assembly,a directional short joint, a lower drilling tool, an alignment device and a dial. The shape structures of the lower slip assembly and the upper slip assembly both are hollow cylinders. The alignmentdevice is mounted on the upper slip assembly. The alignment device is located on the outer surface of the upper slip assembly. An alignment hole of the alignment device is downward. The directional short joint is tightly sleeved with the upper slip assembly. The directional short joint penetrates through the upper slip assembly. The lower portion of the directional short joint is connected with the lower drilling tool. The lower drilling tool is tightly sleeved with the lower slip assembly. The lower drilling tool penetrates through the lower clamping tile assembly. The dial is mounted at theupper end of the lower clamping tile assembly. The dial is perpendicular to the alignment device. The surface of the dial is upward. The drilling directional angular difference measuring device solvesthe problems that manual measurement is difficult, precision is not high, and large errors are caused easily by using manual measurement.

Description

technical field [0001] The present invention relates to the technical field of drilling tool angle difference measurement tools, and more particularly relates to a drilling orientation angle difference measurement device and a measurement method. Background technique [0002] In the process of oil drilling, drilling technologies such as directional wells and horizontal wells have broad application prospects in the field of oil industry, and have become one of the development trends of the world oil industry. One of its key technologies is the precise control of borehole trajectory. Measurement-while-drilling technology is widely used in directional wells and horizontal wells as a tool for real-time monitoring of borehole trajectory. [0003] Before directional well construction, it is necessary to measure the angle deviation between the positioning key of the tool while drilling and the screw bending square mark at the wellhead. At present, the field uses directional person...
