Abstract: The lower heat of hydration and temperature rise of slurry were required for hydrates formation cementing, the traditional experimental methods often result in a great reducing in the application performances. Therefore, the organic and inorganic composites were applied to develop a novel cement slurry, which could be used for hydrates layer in deep-water region or permafrost. Firstly, the micro-encapsulated phase change materials (MPCM) containing low melting point paraffin wax with urea formaldehyde resin shell was prepared by the method of in situ polymerization, the basic performances of MPCM, such as chemical structure, encapsulation rate and phase change properties, were studied. Secondly, the slag and fly ash were firstly added into class G oil well cement to reduced the heat of hydration and temperature profiles through chemical means. Then, the MPCM was added and applied to control the heat evolution and regulate temperature profiles, and a novel micro-encapsulated phase change materials with low melting point slurry was provided. Based on above study, a low temperature profiles and hydration heat cement slurry was developed by using organic and inorganic composites, and the developed slurry could be well applied in deep-water region or permafrost cementing to prevent the destabilization of hydrates.
