| titleOfInvention | Spherical polymer treating agent for high-temperature-resistant drilling fluid and preparation method thereof |
| abstract | The invention provides a spherical polymer treating agent for drilling fluid. The spherical polymer treating agent for the drilling fluid is prepared from the following raw materials in parts by mass: 40-56 parts of an oil phase; 40-56 parts of a water phase; 2-5 parts of an initiator; 2-5 parts of a cross-linking agent. The spherical polymer treating agent for the drilling fluid is three-dimensional spherical in appearance, and the particle size is 100-500 nm. From the experimental results of the embodiments 1 to 3, it can be seen that the spherical polymer treating agent for drilling fluid obtained by the present invention has a slightly reduced viscosity and a slightly increased fluid loss after high temperature aging of bentonite slurry, while the common polyacrylamide and xanthan gum have no viscosity and no fluid loss reduction effect after high temperature aging; the spherical polymer treating agent for the drilling fluid, which is obtained by the invention, can obviously maintain the viscosity of the drilling fluid in a normal range when added into the drilling fluid, and has low filtration loss; common polyacrylamide and xanthan gum have no viscosity after being aged at high temperature, and have very large filtration loss. |
