Under the condition of controlling reasonable drilling fluid viscosity and shear, increase the yield stress and make the dynamic plastic ratio remain above 0.5 to strengthen the rock carrying capacity of fluid system. 3) Lubrication and Anti-stick Technology Drilling fluid speaking, there are three ways to reduce horizontal wellbore friction: ①Assure the hole clean to lower the drilling fluid solid content. ②Reduce the filter loss to lower the mud cake thickness and form a thin and compact mud cake. ③Add lubricating materials to reduce the friction coefficient between drilling tool and borehole.

One of the most important issues is the selection of materials for well casings and piping to handle brines, steams, and brine/steams mixtures.
The chemical composition and characteristics of geothermal fluids have great influence on the degradation process of the used materials.
In geothermal plants carbon steel and martensitic stainless steel are normally used for pipelines and turbine materials.
Both materials suffer from corrosion damage in the presence of condensed steam at low pH values.
Two different materials were studied: ASTM A-53 grade B, which is normally used for surface pipeline, and API-L80 carbon steel, which is used for casing pipe.
