| titleOfInvention | Pentaerythritol polyene monomer to synthesize hyperbranched polymer fluid loss reducer and preparation method |
| abstract | The invention relates to a fluid loss reducer for synthesizing hyperbranched polymers from pentaerythritol polyene monomers and a preparation method, and belongs to the technical field of oil field fluid loss reducer production. It is composed of components such as component A, component B, component C, pentaerythritol polyene monomer, free radical initiator and water. , purify with ethanol, dry and pulverize it into white powder, which is the filtrate reducer product. The ring structure is introduced into the molecule of the fluid loss reducer, which improves the stability of the hyperbranched polymer fluid loss reducer at high temperature, and the temperature resistance can reach 200 °C. It further enhances the ability to resist salt and calcium, the concentration of anti-sodium chloride can reach 30%, and it can also resist compound salt; it has the advantages of green environmental protection, anti-salt, anti-calcium, anti-pollution, anti-high temperature and so on. The invention solves the problems that the existing fluid loss reducer used for oil-based drilling fluid is not environmentally friendly, and the fluid loss reducer used for water-based drilling fluid has poor high temperature resistance performance. |
