| titleOfInvention | A kind of drilling fluid inorganic organic polymer inorganic agent and preparation method thereof |
| abstract | The present invention provides a kind of inorganic organic polymer inorganic agent of drilling fluid, wherein, the inorganic agent is formed to be polymerize by sulfonic acid monomer, carboxylic acid monomer, non-ionic monomer and inorganic material in the presence of initiator；And bentonite is included in the inorganic material.Inorganic organic polymer inorganic agent provided by the invention is respectively provided with stronger filtrate reducing effect in fresh-water drilling fluid, salt-water drilling fluid, saturated salt-water drilling fluid and compound salt-water drilling fluid.It also has stronger caving-preventing ability, can effectively control shale hydration to disperse, control clay pulping, permeability resume figure is high, has preferable reservoir protection effect.And its simple production process, raw material sources are wide, promotion prospect is wide.The present invention also provides a kind of preparation method of drilling fluid with inorganic organic polymer inorganic agent. |
