The Novel Fluid Loss Additive ANMG1305 for Oil Field Cementing

Abstract

Fluid loss additive is the main component of the cementing fluid. This article use monomer the monomers of 2-acrylamido-2-methyl-propanesulphonic acid (AMPS) and N, N-dimethyl acrylamide (DMAA) by the method of aqueous solution polymerization to synthesis the novel fluid loss additive ANMG1305. Discuss the amount of initiator, the molar ratio of monomer, reaction temperature, which the influence on the properties of the polymer. Through the infrared spectrum, thermo-gravimetric analyzer, viscometer, such as instrument on its microstructure and properties were characterized. We know that all the monomers are involved in the reaction and the polymer has an excellent thermal stability though the microstructural characterization and application performance of the novel fluid loss additive.

Synthesis and Properties of Dispersive Type High Temperature Filtrate Reducer Used in Oil Well Cement

“…Conventional filtrate reducer water soluble polymer may boost the mud viscosity, and influence the mud pumping, so the dispersant is input into mud to improve the rheological property, and this causes the ingredients complex. The existing dispersible filtrate reducer is short of the ability of resistance to high temperature and salt [3]. Through analyzing the effect of oil well cementation dispersant and filtrate reducer, we could add the functional group which has the ability of dispersing, and adjust the molecular weight of the filtrate reducer to overcome this fault.…”
