application scope
1.downhole tubing and casing leaks;
2.Casing head and wellhead leaks;
3.Solving some of the cementing quality problems;
4.Sealing the injection hole borehole;
5.Repetitive transformation of oil and gas formations to seal old fractures;
6.Sealing water out layer;
7.casing wireline leakage; downhole tool microfracture leakage; casing pipe column microfracture leakage; bare-eye stratigraphic lift bearing pressure.
technical characteristics
The plugging agent is activated under specific conditions, in an environment without differential pressure, the plugging agent does not react and remains in liquid state.
Factors such as pumping time and method do not affect its curing, the construction of plugging is simple and fast, and the pipe column does not stay plugged after plugging and does not drill plug.
1.Liquid chemical plugging agent, easy to pump, simple construction, fast plugging;
2.Pressure difference activation, only at the leak solidification, the rest of the plugging agent still remains liquid, construction safety;
3.The curing reaction is a flexible solid with elasticity and good sealing performance;
4.The plugging agent is non-toxic and non-corrosive (neutral), friendly to the environment;
5.After curing, the plugging agent is resistant to acid and alkali corrosion, oil resistance and long validity.
technical advantage
Liquid chemical plugging agent, easy to pump, good stability, differential pressure activation, only solidified at the leak, the rest of the plugging agent remains liquid and can be washed out, will not form a large volume of solidification, suitable for complex working conditions, will not bring wellbore safety problems;
Short construction period, fast plugging, filling the section of the well where the leak is located can be repaired, from construction to pressure test pass only 3-4 days;The curing reaction product is a flexible solid, elastic, good sealing performance, acid and alkali corrosion resistance, oil resistance, long validity; the plugging agent is non-toxic and non-corrosive (neutral), friendly to the environment.
