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

Abstract

The embodiment of the invention relates to the field of formation testing, and discloses a formation testing data transmission method, an electronic device and a computer readable storage medium. According to the method, the fountain code encoding mode is used, the overground decoding receiving end is made to receive logging data correctly with the probability as high as possible. Meanwhile, the redundancy of transmitted data is reduced, and the timeliness and reliability of wireless electromagnetic wave logging data transmission are greatly improved through the limited transmission capacity of a downlink channel. When a new feedback adjustment transmission parameter is determined, a two-stage parameter adjustment strategy combining coarse adjustment and fine adjustment is adopted, and thecoarse adjustment link approximately determines the length range of a coded code word of well logging data to be transmitted after coding according to the resistivity of a measured stratum. In the fine adjustment link, specific transmission parameters, namely the coded code word length, are calculated according to the state detected by the word error rate of the uploading channel. The two-stage adjustment strategy improves the determination speed of the feedback parameters and improves the data transmission performance.

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...
