Sinopec News Network News On July 12, the relevant technical staff of Shandong Hehuitong Energy Technology Co.
, Ltd.
came to the Heavy Oil Research Institute of Shengli Oilfield Petroleum Engineering Technology Research Institute to exchange views on the forward-looking "active aerosol enhanced oil recovery technology"
.

Aerosol refers to the liquid or solid particles of 0.
002-100μm uniformly dispersed in the gas to form a relatively stable suspension system.
Active aerosol is to pass active agents such as viscosity reducers, foaming agents, oil washing agents, and expanders through the gas mist It is transformed into a dispersed phase fluid
.

The production-increasing principle of this technology is: aerosol can enter the high permeability zone preferentially to form foam for temporary blocking and turning; the active component can improve the efficiency of oil washing; using nitrogen with high compression energy as the medium, the active aerosol can continue to diffuse and increase energy

At this exchange meeting, the technical staff of Hehuitong Energy Technology Co.
, Ltd.
introduced in detail the technical principles of active aerosols to enhance oil recovery, as well as the use of ordinary heavy oil reservoirs, medium and low permeability sandstone reservoirs, and fractured-cavity carbonic acid.
Application examples of salt rock reservoirs
.

The two parties held discussions on technical issues such as the formation principle of aerosols, their migration rules in oil reservoirs, and the applicable limits of aerosol technology

This technical exchange enables researchers to have a deeper understanding of the technology of enhanced oil recovery by active aerosols, and provides new references and references for the low-carbon and profitable development of heavy oil reservoirs in the future
