| titleOfInvention | A kind of production method of new oil base drilling fluid organic rectorite |
| abstract | A kind of production method of new oil base drilling fluid organic rectorite, the main component of the organic rectorite is rectorite, quaternary ammonium salt.Its production craft step is：A, sodium/lithiumation pretreatment；B, organise reaction；C, filtering, washing；D, ageing, drying, crushing.It is pre-processed it is an advantage of the invention that employing sodium salt and lithium salts composite modification technology and carrying out sodium/lithiumation to calcium base rectorite raw material, improves the colloid rheological property of organic rectorite product；It employs controllable high temperature to organise technique, is fully advanced the chemical reaction for the cation exchange that organises, the quality of organic rectorite is more stable；Employing filter wash technique, removal organises the remaining soluble ion of cation exchange reaction product, further improves the high-temperature stability of product, meanwhile, also reduce the impurity content of product. |
