Background
At present, the horizontal well logging at home and abroad mainly uses a crawler as a pushing tool, and the instrument is lifted up for logging after being sent to a target depth. When the instrument enters a highly-inclined well section, the crawler starts to work, and at the moment, the instrument string carried by the crawler is in a power-off state, so that well logging cannot be performed. But the flow measurement principle needs to be measured in the process of putting the instrument into the horizontal section, flow data when the instrument is put down is obtained so as to improve the test precision, and meanwhile, the downward measurement can also reduce the crawling times and improve the construction efficiency.

In order to achieve the purpose, the underground storage direct-reading device comprises an industrial personal computer, a cable, a ground well logging system, a sleeve inserted into the ground, a well logging instrument positioned in the sleeve, a storage direct-reading dual-mode well logging device and a crawler, wherein the storage direct-reading dual-mode well logging device acquires well logging data measured by the well logging instrument and then stores the well logging data measured by the well logging instrument underground or sends the well logging data to the ground well logging system through the cable, the output end of the ground well logging system is connected with the input end of the industrial personal computer, and the well logging instrument and the storage direct-reading dual-mode well logging device are positioned at the lower end of the crawler.
The storage direct-reading dual-mode logging device comprises a storage electronic circuit, a direct-reading electronic circuit and a battery assembly for providing electric energy.
The storage electronic circuit is used for detecting the voltage on the cable, when the voltage on the cable is larger than a set value, the logging data measured by the logging instrument are sent to a ground logging system through the cable, and when the voltage on the cable is smaller than or equal to the set value, the logging data measured by the logging instrument are stored.
The invention has the following beneficial effects:
the underground storage direct-reading device adopts two working modes of storage and direct-reading during specific operation, when the underground storage direct-reading device works normally, the storage direct-reading dual-mode logging device is used for acquiring logging data measured by a logging instrument, the acquired logging data is sent to a ground logging system through a cable, and after an upstream instrument is powered off, the storage direct-reading dual-mode logging device is used for storing the logging data measured by the logging instrument, so that one-time conveying of a crawler is realized, data processing of two different working modes is realized, the problem that most creepers in the prior art cannot carry out down logging during crawling is solved, the underground storage direct-reading device is very suitable for the actual condition of the creepers in the industry, the cost is relatively low, and the underground storage direct-reading device has a good practical prospect.
