PURPOSE:
Intensification of hydrocarbon production from problem oil, gas and gas condensate wells, in which the flow rate has decreased due to contamination of the bridging agent of the bottomhole formation zone.
TECHNICAL CHARACTERISTICS:
High-energy combustible-oxidizing mixtures are used, the thermal effect of which reaches 15-20 MJ / kg, and hydroreactive substances (HGR) based on sodium, aluminum, lithium and boron.
RECOMMENDED FIELD OF APPLICATION:
Oil, gas and gas condensate fields.
ADVANTAGES:
The high efficiency of the technology is achieved through the use of reactive hydrogen. Unlike other methods of intensification of hydrocarbon production, this technology is complex. It combines thermal, acid and hydrogen methods of influence on the formation. The use of the proposed technology makes it possible to increase the production rate of wells by 1.5-10 times, depending on the reasons for its decrease.
DESCRIPTION:
During a controlled multi-stage thermogas-chemical process, active gases, primarily hydrogen, and acids are formed in the bottomhole zone of the well, which enter the inner space. Thanks to this, the bottomhole zone is effectively cleaned of bridging and the well production rate increases.
