Description
Technical Field
The invention relates to the technical field of cable-free storage type logging, in particular to a large file playback algorithm, a system and a device of a pump-out logging mode.
Background
Pump-out logging is a cable-free storage logging technique, in which no "line" is used to convey the instrument to the destination horizon, but the logging instrument is put into the drill pipe without a cable, after the instrument is conveyed to the destination horizon by using a tripping mode, the instrument is pumped out of the drill pipe by adopting a pump-out mode, and the instrument directly enters the stratum mud. The logging instrument is powered by a battery nipple carried by the logging instrument, the leaning arm of the leaning instrument is opened to be close to the well wall during working, data acquisition is carried out, and acquired data are stored in a storage chip of the instrument. After logging is finished, the instrument is started to the ground to read logging data from the memory and is used after matching with depth. The pump-out logging technology is mainly used for safe and efficient logging data acquisition and reservoir evaluation under complex well conditions.
Because the logging construction mode of the pump-out logging is limited, the logging data of the pump-out logging can only be stored in the instrument, and the instrument can be downloaded only after logging is finished and the instrument is lifted out of the ground. The downloaded log data (time and data) needs to be time-depth matched with the time-depth file (time and depth) recorded on the ground to synthesize the final log data (depth and data), and the process is called data playback.
The traditional data playback algorithm is to match the time and data recorded by the instrument as a whole data with the time and depth data of the ground, and is only suitable for the conditions of short logging time and small data volume. When the logging time is long and the data volume recorded by the instrument is large, the traditional data playback algorithm occupies a large amount of memory of the computer, greatly reduces the processing speed, and even can cause the problem of software flashing back caused by the exhaustion of the memory of the computer.
Disclosure of Invention

Aiming at the situation that the memory overflows due to the large data volume of the existing algorithm, the invention discovers that the original playback algorithm is actually the time-based association between the ground record file and the instrument record file by analyzing the original playback algorithm, and the depth and the data do not participate in algorithm calculation in the association process. The following adjustments were made: the original instrument record file is split into two parts by utilizing the data dictionary principle: the first is a data dictionary file composed of logging data in the original instrument record file; and secondly, an index file consisting of the time in the original instrument record file and the index in the data dictionary file. In the time depth matching stage, the index file replaces the original instrument record file to participate in operation. In the final log generation stage, actual data is extracted from the data dictionary according to the index to participate in the operation.
