Abstract

Provided is a while-drilling imaging logging data transmission method and system. The data transmission method comprises a while-drilling imaging logging data compression method. The data compressionmethod comprises the following steps that the obtained while-drilling imaging logging data are pre-processed, and a while-drilling imaging logging data matrix is obtained; SVD decomposition is performed on the while-drilling imaging logging data matrix, and a plurality of data components are obtained; and a preset number of data components are selected from the data components, the selected data components are encoded, and the encoded data are transmitted to the ground end. According to the while-drilling imaging logging data transmission method and system, single-depth point transmission canbe carried out, multi-depth point transmission can be carried out as well, the while-drilling imaging data compression function can be rapidly and efficiently realized, the data rate is reduced, and the while-drilling imaging data transmission can be conveniently carried out by utilizing the mud pulse with limited transmission capacity so as to meet the requirement of real-time evaluation of the while-drilling stratum.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a method and system for transmitting imaging-while-drilling logging data. Background technique [0002] Horizontal wells are the main way to improve single well productivity and oil and gas field recovery in unconventional oil and gas reservoirs. However, due to factors such as complex structures and differences in reservoir properties, there are often large differences between actual drilling and design, resulting in high-quality reservoirs. Low and long drilling cycle make the efficient development of oil and gas fields more difficult. The geosteering technology while drilling is an important means to solve this problem. [0003] Geosteering while drilling is a technology that uses data such as logging while drilling (LWD) and measurement while drilling (MWD) to judge the formation information encountered in real time and adjust the structural m...
