Embodiment 1

[0030] The present invention is suitable for construction materials and construction techniques of residual acid pools in pre-drilling engineering in oil and gas fields, and includes two parts: acid corrosion-resistant mortar and acid-resistant corrosion-resistant coating that has reached the strength required for production and use through laboratory experiments, wherein the acid-resistant corrosion mortar is guaranteed to be The residual acid pool body is in direct contact with the residual acid discharged from the site after the operation is completed without causing damage, leakage, corrosion, etc. The acid corrosion coating has been verified by experiments that its quality meets the requirements for use, which can ensure that the residual acid inside the residual acid pool will not leak from the pool body into the soil under the foundation and cause environmental pollution.

[0031] The invention belongs to a new production technology in the field of petroleum engineering....

Embodiment 2

[0049] The present invention is a material for a residual acid pool, including acid-corrosion cement mortar and an acid-corrosion coating that has been verified to meet the requirements for use. After the construction of the pool is completed, it is painted with anti-acid corrosion paint, and it can be put into production after treatment.

[0050] The acid-corrosion-resistant cement mortar reaches the designed compressive strength, and on this basis, it is guaranteed that the overall functionality of the residual acid pool will remain intact even when the pool body of the residual acid pool is in direct contact with the residual acid solution, and will not be affected by acid corrosion. Large-area leakage occurs when the pool body is damaged, and it has a certain anti-seepage effect.

[0051] The anti-acid corrosion coating ensures that the residual acid liquid in the residual acid pool will not penetrate into the pool body during the use of the residual acid pool, and maintai...

Abstract

The invention discloses a reacted acid pool construction material for the petroleum industry and a construction technology. Acid-corrosion-preventing mortar and acid-corrosion-preventing paint are combined to be used for construction of a reacted acid pool. The acid-corrosion-preventing mortar takes a potassium silicate solution as an addition material and comprises cement, potassium silicate and river sand in the mass ratio being 1:0.5:4, and the molar ratio of the potassium silicate solution is 1.8-2.0; or the acid-corrosion-preventing mortar takes a sodium silicate and sodium fluorosilicate mixed solution as an addition material and comprises the cement, a sodium silicate and sodium fluorosilicate mixture and the river sand in the mass ratio being 1:0.7:4, the mass ratio of sodium silicate to sodium fluorosilicate is 1:0.15, and the molar ratio of the sodium silicate and sodium fluorosilicate mixed solution is 2.2-2.6. The reacted acid pool construction material has the advantages as follows: an acid prevention function is provided for reacted acid pool construction, the completeness of the whole reacted acid pool is guaranteed, the problem of leakage of the reacted acid pool due to acid liquor corrosion is alleviated, and the whole strength and durability of the reacted acid pool are enhanced.

Description

technical field [0001] The invention relates to an acid-resistant material, in particular to a construction material and a construction technique for a residual acid pool in the petroleum industry, and belongs to the field of petrochemical industry. Background technique [0002] The characteristics of production methods, products, production techniques and equipment of the petroleum industry determine some special requirements for safe production. In the production process, a little carelessness may cause potential dangers to lead to major accidents. Therefore, to ensure the normal production of the petroleum industry, safe production is an indispensable prerequisite. At present, my country has gradually increased technological innovations in oil exploration and collection technologies. Technological innovation takes quality, efficiency and safety into account, and increases the safety and reliability during mining and construction. Before oil and gas extraction, it is ne...
