Purpose of the development: To improve the hydraulic efficiency of the plumes of the wells.

Recommended application field: Plumes of gas and gas condensate wells in the production of which water is present.

Advantages over analogues: Use of inexpensive and domestic chemical reagents. The possibility of introducing a piston into the gas pipeline, both through special launch chambers and without them, as well as the absence of the need to catch the piston at the end of the gas pipeline.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
To combat water stoppers in the plumes of wells, a gel-like viscoelastic piston with an adjustable period of its dissolution in water and in water with condensate is proposed. According to the results of laboratory studies, it is shown that, by varying the formulation of the production of a viscoelastic cleaning piston, it is possible to regulate the duration of its existence from about 40 minutes. up to more than one hour in water and from more than two hours to almost three hours in a mixture of water and condensate. A viscoelastic piston is prepared directly on the field, by mixing water, South Africa and CMC until a uniform mass is formed. After that, the mixture is treated with methanol to reduce the adhesion of the gel to the metal. The piston is launched into the plume of the well, and the composition of the individual components in the piston is selected so that during the period from the start to the exhaust line before entering the gas preparation unit the piston is completely destroyed (dissolved in water).
