Tank container of multifunctional tank car special for oil field

Abstract

The invention relates to a matching device of a multifunctional tank car special for an oil field in the petroleum industrial field, and in particular to a tank container of the tank car. The tank container comprises a tank body, and a special pipeline for waste liquid recovery is arranged on the tank body; a spraying reducer is arranged on a pipeline end of the special pipeline for the waste liquid recovery inside the tank body, a check valve is arranged on the pipeline of the special pipeline for the waste liquid recovery outside the tank body; and meanwhile, a union connector is arranged on the pipeline end part outside the tank body; a tank mouth pipeline is arranged on the lower part of the back end of the tank body, an end part of the tank mouth pipeline is connected with the union connector through a flange. The matching device of the multifunctional tank car can simplify workflows of a cementing truck and an oil recovery hot flushing well in a past oil-water well operation, reduce labor intensity of workers and improve utilization rate of a vehicle.

Description

technical field [0001] The invention relates to a multifunctional oil field special tank car supporting device used in the field of petroleum industry. Background technique [0002] In the process of oil production, after the oil and water well operation is completed, the construction residue needs to be recovered and transported to the designated location for storage and disposal. During the liquid collection process, the cement truck pumps water and needs to insert the hose line into the tank mouth on the top of the tanker. The recovery hose line is relatively long, and due to the high pressure of the cement truck pump water, the hose line swings greatly in the tank mouth. Even thrown off from the mouth of the tank, there is a potential safety hazard and pollution to the well site. Moreover, during the pipeline connection process, the operator needs to climb up and down the tank several times, which is not conducive to the personal safety of the operator; on the other han...

Problems solved by technology

However, a considerable number of oil and water wells use less liquid, and the liquid supply volume of a single vehicle is sufficient. If the sewage tank is still used for liquid supply, it will inevitably cause unnecessary procedural work such as sewage tank hoisting, tank car pouring, pipeline connection, and vehicle placement. operation, which also has a great impact on the construction cost of single well operation

Therefore, it can be seen that the existing finished tank trucks cannot meet the special construction needs of oil and water well operations in the oil field, nor can they meet the special safety production requirements of the oil field, and are likely to cause environmental pollution on the well site, and cannot meet the requirements of clean and environmentally friendly construction; The existing finished tanker has many construction links, the labor intensity of the operators is high, many vehicles are used, and the construction cost is very high
