Abstract

The invention provides a set cement curing mold. The set cement curing mold comprises a top plate, a plurality of partition plates, a bottom plate, connecting rods and a curing cylinder. A curing cylinder is clamped between every two of the top plate, the plurality of partition plates and the bottom plate; the grouting holes in the two corresponding plates are communicated with the curing barrel;when set cement curing is carried out, cement is poured from the grouting holes in the top plate, all the curing cylinders in the whole mold can be filled with the cement, then all the plates can be tightly pressed and locked through the connecting rods so that the sealing performance of cement forming can be guaranteed, the connecting rods are detached after cement curing forming, the top plate and all the partition plates are knocked out in sequence, and set cement with the complete structure can be obtained. The dynamic gas corrosion experiment device comprises a curing kettle, a rotary base, a heater and the set cement curing mold, set cement with a complete structure is tested in the dynamic gas corrosion experiment device, and the corrosion condition and the service life of well cementation cement paste injected into an actual stratum can be reflected more truly.

Description

technical field [0001] The invention relates to the technical field of cement stone maintenance, in particular to a cement stone maintenance mold and a dynamic gas corrosion experiment device. Background technique [0002] Nowadays, the exploitation of oil and gas resources needs to drill the formation and establish oil and gas passages from the ground to the reservoir. In the process of drilling the formation, in order to stabilize the well wall and seal the formation fluid, it is necessary to inject cement slurry into the gap between the casing and the formation to form cement stone to protect the wellbore and make the drilling work go smoothly . Because the formation contains a large amount of corrosive media, the corrosive media reacts chemically with the cement stone, resulting in an increase in the permeability and porosity of the cement stone, and the structural integrity of the cement stone is destroyed, and then the corrosive medium penetrates further, Corrosion o...
