| titleOfInvention | Isolation method of water influxes to well |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: isolation method of water influxes to a well includes determination of the well intake under the maximum pressure, injection of a gel-forming compound to the formation with further addition of a compound non-filterable to the formation. The above compounds are pumped down at simultaneous pressure control at the well head. The process holding of the well is made under pressure. Excess of the compound non-filterable to the formation is flushed from the annular space by counter-pressure back-flushing. The gel-forming compound is used with the following ratio of ingredients, wt %: xanthane biopolymer 0.4-0.6, triethanolamine titanate-1 0.5-0.8, water - the remaining part in volume of V gf calculated as per the specified mathematic expression. Injection is made with the permanent flow rate under pressure at least equal to 0.7 of the formation intake. The gel-forming compound is used with addition of precipitated chalk stone as the compound non-filterable to the formation with the following ratio of ingredients, wt %: xanthane biopolymer 0.4-0.6, triethanolamine titanate-1 0.5-0.8, precipitated chalk stone 5-10, water - the remaining part. n EFFECT: improvement of processability and efficiency in isolation of water influxes to the well due to creation of a stronger water shutoff screen. n 1 ex, 3 tbl |
