Description

Technical Field

[0001] The invention relates to the technical field of underground goaf cavity shape measurement, and in particular to a sonar laser integrated cavity measurement system and a cavity measurement method. Background Art

[0002] The acquisition of relevant information on the shape and volume of the salt cavern gas storage cavity is the basis for its construction. Currently, sonar technology is mainly used for cavity measurement in salt cavern gas storage at home and abroad. In the process of salt cavern gas storage construction, sonar cavity measurement is mainly used in three aspects: measuring the cavity shape during the cavity making process of new wells, and adjusting the cavity dissolution process in time according to the measurement results; measuring the shape of old cavities, and screening and transforming the cavities according to the measurement results; measuring the cavity after injection and production operation, understanding the changes in the cavity, and taking relevant measures in time to ensure the safety of the salt cavern gas storage. Summary of the invention

[0003] The inventor found in the long-term cavity measurement process that the existing sonar cavity measurement technology has two main shortcomings. First, because the attenuation of sound waves in gas is much greater than that in liquid, it is difficult to measure the gas cavity and the accuracy is low. At the same time, the measurement distance cannot meet the needs of large-sized cavities. Taking the most representative German SOCON BSF2 sonar instrument on the domestic market as an example, its maximum range in natural gas not less than 15MPa is 80 meters, while the radius of many domestic cavities has exceeded 100 meters, and as the pressure decreases, the measurement accuracy and range are further reduced. On the other hand, since the sonar has large reflection interference at close range, it is impossible to directly detect smaller spaces such as the neck of the cavity. It is necessary to add a reflection tube to artificially extend the reflection distance of the sound wave signal. Therefore, during the construction process, it is necessary to lift the instrument to the ground after the cavity measurement is completed, and then install accessories separately and then enter the well for measurement, which greatly increases the workload on site. Especially in the process of measuring the gas cavity, it is necessary to install a blowout preventer for pressure operation. Each additional lifting process greatly increases the construction risk and cost.

[0004] In order to solve the problems of limited measurement accuracy and distance of the gas cavity in salt cavern gas storage, and complex measurement procedures in small spaces such as the cavity neck, the present invention proposes a sonar laser integrated cavity measurement system and cavity measurement method to achieve low-cost, high-efficiency and high-precision cavity measurement.
