Salt-based compound.

Технология

This means that QUICK-STONE ™ within a few minutes passes from liquid to solid state, that blocks the flow of gas, water or oil in the channel faces.

The QuickStone ™ system is characterized by a controlled rapid strength development time, accurate to the minute. The system thickening time depends only on the formation temperature in the area of application. After thickening, the composition is easily removed from the bottom hole zone (easily drilled out), and is also capable of completely dissolving in hydrochloric acid (15% by weight).

During the delivery of material through the pipe space (during the lost circulation control works), the material is in a liquid state, and the prescription is prepared so that after flowing out of the pipe and the estimated filling of the repair zone by the system, the material sets within 2-5 minutes.

Modifications to the QuickStone ™ compound for application depending on the reservoir temperature:

• ArmoBlock™ – 20-50°С;
• QuickStone LT™ – 45-60°С;
• QuickStone MT™ – 61-85°С;
• QuickStone HT™ – 86-150°С.

APPLICATION

• control of circulation losses of varying intensity, up to catastrophic;
• isolation of water and gas kick zones;
• temporary killing of wells;
• elimination of casing leakage;
• installation of bridges for sidetracking-the possibility of pumping the composition through the bit/КНБК/MWD;
• as an alternative to installing a packer-the material does not shrink.

ADVANTAGES

• no formation damage
• Zero static shear stress, solid-impermeable,
• the ability to change the density of the system from 1.40 to 2.00 g / cm3;
• easily pumpable through DP / BHA / MWD / drill bit/ CoilTube;
• shortened WOC time (3 hours);
• easily drilled out without affecting the drilling fluid
• easily removed from the bottomhole zone - soluble in 15% HCl;
• long-term solution - will not deform and break;
• system does not shrink, the average particle size is 7-15 microns;
• the composition does not have thixotropic properties;
• neutral to aggression (hydrogen sulfide, bicarbonate, etc.);
• withstands up to 40% of pollution of organic and inorganic origin (HC, various water-based fluids). These contaminants do not have a negative effect on the shrinkage of the material, on the process of its thickening, changes are observed only in a decrease in the strength properties of the obtained sample.
