Product name: The biocatalytic deplugging throughput enzyme
Near wellbore analysis: The damage of the oil and gas well plugging for the specific circumstances of the damage of the oil and gas layer, in general, in the construction process of drilling, production, workover, water injection, fracturing, a long period of exploitation, there will be varying degrees of damage oil and gas layer original physical - chemical equilibrium, causing formation damage. The main stratigraphic damage caused permeability reduction factors not normally mined following aspects:
Organic components of crude oil in the resin and asphaltene changes in differential pressure degassing near wellbore area and of borehole wells barrel deposition, the formation of the organic scale blockage.
(1) foreign drilling and workover fluid and reservoir rock minerals and fluid compatibility damage clogging.
(2) the capillarity damage, shale hydration swelling damage.
(3) organic scale of the near wellbore and borehole deep, relatively thick asphalt oil, gum, wax and other heavy-duty components during production and shut-in during the deposition causing permeability reduction.
(4) solid particles clogging.
(5) drilling, fracturing, and the perforated completion polymer damage caused by the blockage.
(6) The bacteria produce mucus biopolymer clogging, also intensified inorganic scale, precipitation, flocculation of the organic scale.
(7) embrasure near the near wellbore residual oil, organic dirt with the well into the liquid in the temperature difference changes in the inorganic scale formation of deposits and organic scale composite to increase the flow resistance of the oil and gas layer near wellbore penetration pore, resulting in oil and gas wells not smooth, resulting in decreased permeability.
