| titleOfInvention | Resin coated sand for realizing steering fracturing, and preparation method and application thereof |
| abstract | The invention provides resin coating sand for realizing steering fracturing, which comprises the following preparation raw materials in parts by weight: 100 parts of main material, 0.1-1 part of silane coupling agent, 10-15 parts of polyether amine resin or sulfonated polyether amine resin, 1-3 parts of polyvinyl alcohol, 1-10 parts of hyaluronic acid modified poly-thioether ketone and 0.1-2 parts of chitosan; the main material is selected from one or more of quartz sand, shell powder, silicon dioxide and titanium dioxide. The resin coating sand provided by the invention belongs to a high-strength plugging material, and is free from backflow, so that steering fracturing is realized, the construction efficiency and the oil and gas production of an oil and gas well are greatly improved, and the market prospect is good. |
