Sand-Carrying Mechanism and Rheological Characters of PE-SCA101 Transporting Agent
Abstract：In order to solve the difficulty in the stability of carrying slurry used for CRI, a type of transporting agent PE-SCA101 has been developed and its sand-carrying mech- anism and rheological characters are studied. The results indicate that the viscosity of carrying fluid is not a major factor affecting on sand-carrying ability, and that the sand- carrying ability of a carrying fluid is a function of the combination of drilling cutting grain size, carrying fluid viscosity, yield stress, surface activities, sand ratio and so on. If the particle diameter of the drilling cuttings is 161 μm, the dosage of the PE-SAC101 can be 0.2%, and if the sand ratio ranges from 10-25%, a stable sand-carrying slurry will be prepared.
