Latest Patents

One of Jiwen Xiao's latest patents is titled "Method of encoding and decoding downlink instructions based on mud flow rate." This innovative method includes both an encoding and a decoding process that allows for the transmission and reception of instructions by controlling the mud flow rate during drilling. Notably, this method does not rely on a fixed voltage threshold for determining '0' and '1' symbols. Instead, it uses the voltage change rate as a standard for judging level transitions, which helps avoid decoding failures that can occur when voltage sampling values do not reach the fixed threshold at greater well depths.

Another significant patent is the "Service table for polling data of downhole transmission device in measurement-while-drilling." This service table architecture includes various parameters such as frame numbers, data item counts, and device addresses. It has been successfully implemented in actual drilling devices, completing field operations for multiple wells. Compared to previous simplified service tables, this innovation supports multiple downhole transmission devices working simultaneously, thereby enhancing drilling efficiency and reducing costs.
