At present, beach and dam reservoirs are found in the Green River group of the eucause Taber basin, the Ruman cave Galhak group of the Nansudan Melut basin, and the Erdos basin, the quasi-Sago basin, the Tarim basin, the Jianghan basin, the Subei basin and the Bohai Bay basin in China. In order to make up the deficiency of the one-hole underground observation and deeply research the reservoir, the application of the geological thinking of 'ancient theory' to the reservoir body of the modern sedimentary beach is one of the most important research modes. The beach dam is distributed in a shoal lake (sea) area, mainly sandstone is used, a thin argillaceous layer is sandwiched, and the key of the research is to take out the sand deposited on the beach dam, which can furthest retain the underground lithology and the structural distribution.

The gravity sampler samples by means of impulsive force generated by self weight of equipment, has the advantages of simple and convenient operation, limited insertion depth due to the influence of gravity and is mainly used for softer sediments; the vibrating sampler mostly adopts electric drive vibrators to generate a vibrating effect, and has the defects of high electric power loss, limited field working time and being mostly used for harder sediments; the excavation type sampler is mainly used for large-scale surface layer sampling, and has the defects that the deposition sequence, the deposition structure and the structure of sediments are difficult to ensure, and well-preserved long rock cores are difficult to obtain; grab bucket type sampler is used for sediment top layer sample mostly, and simple structure, the shortcoming is that the sample depth is limited, and is big to the sample disturbance, and the leakproofness is lower, can make the sample run off. At present, the column sampler is used most, and part of the column sampler with simple structure lacks an effective sediment sealing device, so that the sediment can cause sample loss when being pulled out; the sampler with a complex structure basically realizes effective sealing of sediments after sampling, but water in samples in a shoreside lake (sea) area is difficult to discharge, and the sampling barrel is difficult to pull out from the ground only by manpower after the samples are taken out, so that no relevant description is provided for how to effectively discharge water in the sampling process and take out the samples from the ground in the current research. In summary, the following problems mainly exist in the current sampler: (1) how to ensure vertical drilling and ensure that the deposition sequence, deposition structure and structure of the sediment are perfectly preserved in the sampling process. (2) How to carry out the row of pressure, drainage and effectual sealing to the sample of taking out in order to guarantee sampling efficiency. (3) How to take the sample to the ground without damaging the deposition sequence, deposition structure and configuration of the deposit after the sampling is finished. Therefore, a fixed-point in-situ coring device and a power lifting device which have a water outlet and can be sealed are needed, and underground sand bodies are taken to the ground surface to the greatest extent.
