Product Description
Base pipes and screen jackets and sand control well screens
Base pipes and screen jackets, which is also called sand control well screens, which is used in the oil well, gas well and water wells. The base pipes screen jackets is constitute of API standard base pipes and the Johnson type well screens as the jackets wrapped outside of the base pipes.
Sand control screens is a new efficient technology of the mechanical sand control with excellent performance in practice by its high permeability, high strength, high deformation a adaptive capacity, high reliability and good anti-corrosion property.
Pipe based screen combines the hydraulic efficiency of a continuous slot screen with the strength of a pipe. This pipe strength allows smaller wrap wires to be used, yielding greater open area. Longitudinal support rods direct inflow to the nearest pipe perforation. Screen and pipe are welded together to make a rugged, reliable unit for deep vertical wells and long, horizontal remediation of supply wells. Fittings are available to meet most well design and installation requirements.
The pipe based screen is recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
Base pipes can be manufactured using stainless steel grades or API 5CT carbon steel casing. OASIS uses prime pipe, thoroughly cleaned and de-burred after perforating.
Sand control Screen Features Materials and Anticorrosion Ability.
1. For common wells, the base pipe is API casing or tubing (J55, N80, L80,etc.). Sand control filtration jacket and protective shroud are made of high quality stainless steel.
2. For special wells in H2S, CO2 or C1 corrosive environment, the base pipe is anti-corrosion casing or tubing, even is stainless steel tubing. Sand control filtration jacket and protective shroud are made of high quality stainless steel.
3. Have anti-corrosion ability to acid, alkali, or salts.
