Oil and gas field storage bag and preparation method thereof

Abstract

The invention discloses an oil and gas field storage bag, which comprises a bag body; a liquid inlet and an exhaust port are formed in the bag body; the bag body is formed by butting at least a first bag body and a second bag body different in size, and the first bag body and the second bag body combined together in a melt welding manner by heating respective binder layers; a geotechnical cloth layer is bonded below the bag body; the first bag body and the second bag body are both first impermeable membranes capable of resisting acid and basic solution; each first impermeable membrane consists of a first impermeable layer, a second impermeable layer and a third impermeable layer which are arranged in sequence and bonded together, and moreover, black master batches are added to each first impermeable membrane. The first bag body and the second bag body are combined together in the melt welding manner, form a whole, and are not easy to crack; the oil and gas field storage bag disclosed by the invention can be suitable for any hostile environments; by the geotechnical cloth layer, the service life of the bag body can be prolonged, and the bag body can be effectively prevented from being damaged by certain sharp objects.

Description

technical field [0001] The invention relates to an oil and gas field storage bag, in particular to a novel oil and gas field storage bag that is convenient for transportation, quick and flexible, applicable to various environments, and capable of withstanding water injection pressure and acid and alkali concentrated liquid. Background technique [0002] With the rapid development of industrial technology in today's world, as the raw materials of many industrial productions, the use and storage of chemicals came into being. The use of the chemical industry is increasingly developing towards a new level of large-scale and high-efficiency. Now the country has more and more stringent requirements for environmental protection. The extensive use of chemicals and the later solution treatment will inevitably lead to leakage, which is bound to cause environmental pollution. Therefore, the use, storage, and solution disposal of chemicals become the top priority. Nowadays, metal cont...

Problems solved by technology

At present, in the prior art, it is about laying plastic film in the anti-seepage channel to prevent seepage, but the plastic film has poor crack resistance, especially when encountering stones or other sharp objects, it is easy to puncture, and the anti-seepage effect is poor. Moreover, the open film is arranged in the anti-seepage channel, and various substances will leak out over time, making it impossible to store for a long time
