Abstract

The invention provides a novel method for winding an antenna of a downhole instrument. The method for winding the antenna of the novel underground instrument has the following steps: S1. Material preparation: (1). Antenna housing body, antenna coil, skeleton and antenna fixed joint; S2. Process: (1) Drilling groove: drilling device through the antenna housing The main body of the antenna cover is drilled so that an antenna cover slot and a plurality of antenna slots are formed on the main body of the antenna cover, and the plurality of antenna slots are distributed in a circular array; (2) Drilling gaps: The skeleton is processed by equipment. , to open the toggle gap; (3) Fixed point: open an antenna fixed point on the skeleton. The new method for winding the antenna of the downhole instrument provided by the present invention can adapt to the harsh environment in the well, and is assembled on the main body of the antenna cover through high temperature heating, so that the firmness is higher, and the risk of loosening is avoided, thereby reducing the workload, Advantages of cost and probability of maintenance.

Description

technical field [0001] The invention belongs to the technical field of downhole instrument antennas, and in particular relates to a novel winding method for downhole instrument antennas. Background technique [0002] At present, wireless measurement while drilling technology is the main direction of petroleum engineering technology development, and it is an advanced measurement instrument commonly used in international drilling. Wireless transmission mainly transmits electromagnetic waves through the antenna coil wound on the drill collar. Due to the high temperature, high pressure, high corrosiveness, strong vibration and high wear and tear in the underground working environment, the antenna coil is usually protected by a cover. [0003] However, in the prior art, the traditional antenna coil cover is usually a detachable structure, which is convenient and simple to wind the antenna coil. Due to the harsh underground environment, the cover has the risk of loosening, requir...
