  • Can a new cement fluid loss additive resist high temperature and high salt content?
  • To solve the problems, a novel cement fluid loss additive HTF-200C, which can resist high temperature and high salt content, was synthesized using the monomers of 2-acrylamido-2-methyl-propane sulphonic acid (AMPS), N, N-dimethyl acrylamide (DMAA) and a new compound with double carboxyl by the method of aqueous solution polymerization.
  • Why is it difficult to hydrolyze cement slurry in China?
  • At present, the normal fluid loss additives in China, which often have relatively poor ability of salt-tolerance and high temperature-resistance [4,5] , are easy to hydrolyze with the increase of temperature and result in far delayed solidification of cement slurry , so it is hard to satisfy the needs of ce- menting complicated strata.
  • Can acrylate latex be used as a polymer cement modifier?
  • Acrylate latex modified by the silane coupling agent VTS had excellent performance on fluid loss control, as well as mech. properties for oil well cement. These results have a potential significant value for the development of a new polymer cement modifier with high thermal stability and durability.
  • Why is HTHP important in well construction?
  • The High-Temperature/High-Pressure (HTHP) fluid loss of a drilling fluid is very important in well construction because it has a direct correlation with the cost of maintaining the fluid and success of drilling the well. The HTHP filtrate value is set to minimize hole instability, filtrate invasion, and prevent differential sticking.
