In modern drilling operations, the use of drilling polymers and polymer additives has revolutionized the way drilling fluids are formulated and employed. Drilling Polymers effectively flocculate drill cutting, high and low-quality clay, driving them out of the well, and inhibiting their dispersion. Its usage in drilling operations is proven the remove fluid loss, increase drilling mud viscosity, and remove colloidal from deep drilling foundations.
Drilling
Polymers serve multiple purposes in drilling operations, commonly used as
additives in drilling fluids, or as drilling mud. The main purpose of using
this is to control viscosity, also suitable for plumb shafts, horizontal wells,
deep shafts, etc. The absorbency and retention capacity help to minimize waste
disposal costs, treatment time, and environmental impact.
Advantages of Using PHPA-Based Drilling Polymer
PHPA (partially hydrolysed polyacrylamide) are
indispensable polymer in various industries. These water-soluble compounds
possess exceptional flocculation and viscosity-controlling properties.
·
Enhanced Wellbore Stability - It prevents
the formation of collapse and minimizes the risk of wellbore instability.
·
Improved Drilling Fluid Performance – This
polymer is considered a fluid loss control agent that enhances drilling fluid
properties, improves fluid circulation, minimizes fluid loss into the formation,
and promotes efficient drilling performance.
·
Excellent Cuttings Removal – The viscosity-controlling
property supports in effectively transporting drilled cutting to the surface.
·
Removes excess water that surfaces during
excavation
·
Reduce Friction and wear which helps to
extend the lifespan of drilling tools and reduce maintenance costs.
·
Environment-Friendly Solution that
ensures minimal environmental impact, aligning with sustainability goals.
The use of PHPA-based Drilling Polymer not only
ensures enhanced slurry rheology but also lessens mud rings, bit balling, and
clay formation booting-off, with a significant reduction in drill pipe torque
and pumping pressure.
Chemtex Speciality Limited Offers CX Drill,
PHPA-based zwitterionic charged polyacrylates used for the removal of both
inorganic and organic matter, colloidal and particulate suspensions of
impurities.
It is incorporated with water shut-off capabilities that
find extensive usage mainly as viscosifier preparation of stabilizing and
lubricating mud in drilling for deep foundations like piling excavations,
trenching excavations, drilled shaft, auger drilling, reverse circulation
rotary drilling and horizontal directional boring, etc.
When it is mixed with water, forms a clear, solid-free,
viscous, easy-mixing, water-dispersible, non-Newtonian solution that can be
used as a replacement for bentonite slurry during piling excavation as a
viscous borehole stabilizing fluid to prevent reactive shale and clays from
swelling and sloughing.
