In drilling operations, modified starch is used to improve the rheology of the mud system, stabilize it and increase the filtration properties of the mud. The use of modified starch helps to drill the well more efficiently by providing better penetration in the borehole.
Use of modified starches in drilling Its use increases the viscosity of the mud, increases the bearing capacity of the mud in the well and helps stabilize the well walls. In addition, modified starches reduce the settling of mud sediment in the borehole, allowing pumps and equipment to operate more efficiently.
The use of modified starches in drilling is preferred due to their environmental friendliness and low toxicity. In addition, modified starches have a high pH tolerance and are resistant to temperature changes.
Some features of modified starches used in drilling are:
High viscosity: Modified starches increase the viscosity of the mud system and provide better penetration in the borehole.
High stability: Modified starches increase the stability of the sludge system, improving the filtration properties of the sludge.
Low filtration loss: Modified starches provide a smoother surface in the borehole by reducing the filtration loss of mud.
High pH tolerance: Modified starches can remain stable at high pH values and maintain the stability of the sludge system.
Environmentally friendly: Modified starches are environmentally friendly and low-toxic, reducing the environmental impact in the borehole.
