| titleOfInvention | Method for elimination of high-pressure well flows |
| abstract | FIELD: well drilling. SUBSTANCE: injected in well in two portions is bridging material. First portion contains cement, calcium chloride and water, and the second portion contains synthetic latex and ucramine - surfactant based on neutralization product of fatty and naphthenic acids with amino compounds. Additionally injected between portions of bridging material and after injection of bridging material is fresh water. Bridging material is injected until building up the pressure of 5 MPa. Initial ingredients of bridging material are used in the following amounts, mas. cement 67, 84; calcium chloride 3.0; synthetic latex 2.0; ucramine 0.02; water 27, 14. EFFECT: higher efficiency. 2 dwg, 1 tbl |
