Problems solved by technology

The drive head is affected by the reaction force of the mud during the movement, and the uneven pressure changes cause the signal to be rough and have sawtooth waves, which interferes with the signal and affects the later decoding

Abstract

The invention relates to the technical field of wireless inclinometers while drilling, and particularly discloses an anti-interference pulse generator driving head. The anti-interference pulse generator driving head comprises a mushroom head and a flow limiting ring, the mushroom head is connected with the flow limiting ring in a sliding fit mode, one end of the mushroom head is of a first conicalstructure, a second conical structure is arranged on the flow limiting ring, the first conical structure is matched with the second conical structure, and the first conical structure and the second conical structure are both conical. According to the anti-interference pulse generator driving head, by arranging the mushroom head and the flow limiting ring structure, the waveform intensity is adjustable, the anti-attenuation and anti-interference capabilities of the transmitted signal are stronger, the pressure change is more uniform, the signal is more anti-interference, and later decoding ismore facilitated.

Description

technical field [0001] The invention relates to the technical field of wireless inclinometer while drilling, in particular to an anti-jamming pulse generator driving head. Background technique [0002] The wireless inclinometer while drilling is widely used in directional drilling in geological exploration, oil development, coal mining and municipal, transportation, water conservancy and other excavation-free projects. The wireless inclinometer while drilling consists of surface equipment and downhole instrument strings. The data processor of the ground equipment is responsible for the signal transmitted by the mud pulse pressure of the downhole instrument series, data decoding, and transmission to the remote data processor for engineering personnel to use. The downhole instrument string is composed of a probe assembly, a pulse generator, a power supply assembly, and an instrument seat key. The pulse generator is responsible for generating mud pulse pressure in an orderly ...
