Formation test data transmission method, electronic device, and computer-readable storage medium

Abstract

The embodiment of the invention relates to the field of stratum testing, and discloses a stratum testing data transmission method, electronic equipment, and a computer-readable storage medium. In the present invention, the fountain code encoding method is used to enable the ground decoding receiver to correctly receive the logging data with as high a probability as possible while reducing the redundancy of the transmission data, and the limited transmission capacity of the downlink channel is used to greatly improve the wireless electromagnetic wave logging Data transmission timeliness and reliability. When determining the new feedback to adjust the transmission parameters, a two-level parameter adjustment strategy combining coarse adjustment and fine adjustment is adopted. The coarse adjustment link roughly determines the code word length range of the encoded code word to be transmitted according to the measured formation resistivity ; The fine-tuning link calculates specific transmission parameters according to the state detected by the word error rate of the upload channel, that is, the length of the encoded codeword after encoding. The two-level adjustment strategy improves the speed of determining the feedback parameters and improves the performance of data transmission.

Description

technical field [0001] Embodiments of the present invention relate to the field of formation testing, in particular to a method for transmitting formation testing data, electronic equipment, and a computer-readable storage medium. Background technique [0002] Formation testing is to conduct on-off well tests on oil and gas layers during drilling or after well completion to obtain various parameters and fluid properties of formations under dynamic conditions, so as to make qualitative or quantitative evaluations of formations. The two-way transmission system of formation test data is mainly to send the downhole data to the ground control station in real time during the test process, so as to solve the problem of real-time monitoring of the underground construction process and real feedback of the bottom hole situation, so that the accuracy and effectiveness of on-site operation decision-making are greatly guaranteed. , and send a small amount of control instructions to downh...
