Product Description

Product Description

After the perforated interval is filled with the coating material, the wellbore can be cycled to meet the requirements of workover operations. The positive pressure coating can still prevent solid and liquid leakage to the pay zone.

Our Advantages

1, rigid support support for rigid solid particles, straight diameter is greater than the diameter distribution of the air layer pore throat.
2. Elastic seal The seal is elastic gel to eliminate the residual permeability between the rock and the support.
3. Under the action of positive pressure difference, the shielding agent is pressed on the rock surface, and the rigid particles remain and the elastic gel closes the permeability between the rock and the rigid particles.

Elastic modulus of particles with heat When the extension of roll time has increased
Between even more than 30 days, its elasticity The strength can still be controlled in temporary plugging Within the effective range of the agent; Temporary plugging agent Effective time at 180ºC More than 30 days.

Under the conditions of 180ºC and 30MPa pressure difference, the particle can meet the requirements of unidirectional temporary plugging of abnormally low pressure gas layer for up to 30 days.

Typical construction well Case
1. Application in Yacheng 13-1 abnormally low pressure gas field.
The field application of well A13 proves that the shielding temporary plugging can be used at 179ºC high temperature, 30.0MPa large pressure difference and continuously and effectively for more than 48t, and the construction is a complete success.
2. Application in the Shattleuk abnormally low pressure gas field
Field application proved that the shielding fluid could be used at 145 ºC; Under the condition of large pressure difference of 26.0MPa, continuous and effective use for more than 240h.
Nearly 160 Wells have been constructed.
3. Part of construction Wells in Malei Gas field and Dabei Dabat Gas field in Turkmenistan
