Sediment removal device used for sleeve of underground water-sealed stone cave storage cavern

Abstract

The invention discloses a sediment removal device used for a sleeve of an underground water-sealed stone cave storage cavern, and relates to the technical field of underground water-sealed stone cavestorage caverns. The sediment removal device comprises a fixed pipe string arranged in the sleeve, a suction assembly and a jet spray nozzle. The upper end of the fixed pipe string communicates with the ground. The suction assembly is connected with the lower portion of the fixed pipe string and comprises a suction pump and a motor. The suction pump can suck clear water and sediment. A liquid inlet of the suction pump communicates with the inner portion of the sleeve. A liquid outlet of the suction pump communicates with the inner portion of the fixed pipe string. A rotation shaft of the suction pump is connected with an output shaft of the motor. The jet spray nozzle is arranged below the suction assembly. A liquid inlet of the jet spray nozzle communicates with the liquid outlet of the suction pump through a jet pipe. Part of underground water sucked by the suction pump is sprayed towards the sediment depositing in the sleeve through the jet spray nozzle so that the sediment in the sleeve can be crushed, the crushed sediment is sucked through the suction pump together with the underground water and flows back through the fixed pipe string. The sediment removal device is good in sediment removal effect, high in sediment removal efficiency and low in manual workload.

Description

technical field [0001] The invention relates to the technical field of underground water-sealed cavern storage, in particular to a sand removal device used for sleeves of underground water-sealed cavern storage. Background technique [0002] With the continuous deepening of the contradiction between the supply and demand of crude oil in our country, the establishment of a complete oil storage system has become a top priority. Among them, the underground water-sealed cave storage is one of the main oil storage facilities in my country. The underground water-sealed cavern storage is a kind of storage facility that uses the static pressure of groundwater to realize the stable storage of oil and gas, and is usually set up in places with stable groundwater levels. Specifically, caverns are excavated in the hard rock below groundwater to form oil storage caverns, and then oil and gas are directly injected into the caverns for storage. Since oil and water are immiscible, and the s...
