Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plugging equipment, and specifically relates to a geological exploration hole sealing device. BACKGROUND

[0002] In the field of geological exploration, drilling operation is one of the key means to obtain underground geological information. In order to ensure the accuracy of exploration data and the smooth progress of subsequent related operations, it is essential to effectively seal the hole. The existing geological exploration hole sealing device has certain limitations in design and application, mainly in terms of adaptability.

[0003] Most of the common hole sealing devices on the market can only adapt to fixed diameter geological exploration holes. In actual geological exploration process, due to the differences in different geological conditions, exploration purposes and drilling equipment used, the diameters of the exploration holes formed are often different. Such single adaptability hole sealing device is difficult to play a good hole sealing effect when facing exploration holes with different diameters.

[0004] For example, when the diameter of the exploration hole is slightly larger than the adaptability diameter of the hole sealing device, the device cannot closely fit the hole wall, which may lead to loose sealing, and the mud, debris and other external materials may penetrate into the hole, affecting the accuracy of subsequent exploration data collection and possibly damaging the instruments and equipment placed in the hole. When the diameter of the exploration hole is smaller than the adaptability diameter, the hole sealing device cannot be smoothly installed into the hole, or even if it is forcibly installed, it will change the original structure of the device due to excessive extrusion, affecting its normal sealing function and service life.

[0005] Such hole sealing device that can only adapt to fixed diameter exploration hole has poor universality and flexibility in actual application, greatly limiting its use in diversified geological exploration scenes, increasing the cost and time cost of exploration operation, because special hole sealing devices are often needed for exploration holes with different diameters, and when special conditions require sealing of non-standard diameter holes, additional corresponding devices need to be customized, which undoubtedly brings many inconveniences and additional burdens to geological exploration work.

[0006] Therefore, a geological exploration hole sealing device is proposed. CONTENT OF THE UTILITY MODEL
