The invention relates to a well cementation
cement sheath performance
simulation experiment device and an experiment method. The experiment device comprises one set of
cement cake circulation device, one set of
cement sheath performance detection device and one set of cementing face shearing force experiment device. The experiment method comprises the following steps of: simulating the manufacture process of a well cementation
test sample under the practical underground warm-pressing condition; detecting the sealing performance and the
corrosion resistance of the cement ring; detecting the sealing performance and the
corrosion performance of the cement ring; and detecting cementing face shearing force between a casing
pipe test sample and the
cement sheath and cementing face shearing force between the
cement sheath and a stratum
test sample. According to the invention, because the adopted casing
pipe test sample has the same size and the material with the casing
pipe material applied in the practical well cementation, the adopted stratum test sample is a standard artificial stratum test sample, the
porosity-permeability characteristic, the strength characteristic, and the fluid characteristic and the like of the adopted stratum test sample are same with the stratum characteristic in the practical well, the invention can be used for truly simulating the dynamic variation of full-size well cementation, and the
simulation condition is accurate. The invention can be widely applied in
simulation experiments of various well-cementation dynamic variations.
