Cementing Technology of Salt-Paste Bed

Resumo

During more than 100 years of oil development, cementing technologies have been constantly improved. Depending on the well conditions, the technologies vary in number of stages, cementing mixture composition, and methods to provide leakage-proof and gas-tight cementing, etc. In this paper the authors analyzed the creep law application and its models for the salt-gypsum layer and performed the comparative adaptability evaluation of cementing methods in the salt-gypsum layer.
