At present, with the continuous development of oil and gas development technology and the continuous improvement of oil and gas reservoir evaluation capability, new oil and gas reservoirs are continuously discovered in various sea and land basin sunken deposition areas worldwide.
The current oil and gas reservoir blocks are distributed in various high, medium and low latitude climates of all continents around the world, including low latitude equatorial rainy climates, tropical marine climates, tropical dry and wet climates, tropical monsoon climates, tropical arid and semiarid climates and the like; subtropical arid and semiarid climates in mid-latitude, subtropical monsoon climates, subtropical humid climates, subtropical marine climates, and the like; secondary polar continental climates at high latitudes, and the like.
In order to facilitate oil and gas exploitation, the oilfield exploitation working party can set up a pipe storage center nearby to perform open-air piling management of the pipes. The special petroleum pipe and auxiliary materials (not limited by the pipe, can be used for surface coating, such as protection ring, packing belt, screw thread grease, etc.) have different corrosion rates under different environmental conditions. Namely, under different environmental conditions, the effective life deviation of the pipes and auxiliary materials of the same material is larger.
However, the current evaluation means and evaluation modes and evaluation equipment cannot accurately feed back the validity period of the petroleum special pipe and auxiliary materials under certain environmental conditions. Because of improper or even incorrect collocation, the corrosion rate is too fast or even increases due to the inability to adapt to the local environmental climate, resulting in damage to the structural integrity and sealing integrity of the oil-specific tubing, and thus failure or greater risk of use.
For example, chinese patent publication No. CN204086100U discloses a deep sea corrosion environment simulation device, which transmits the rotation motion of a magnetic stirring motor to a magnetic stirrer through a belt, and at the same time, the magnetic stirrer drives a plurality of stirring paddles inside the autoclave body to achieve the purpose of simulating the flowing state of seawater and realizing the accelerated corrosion of a test sample.
