Product Description:
Stainless steel gravel prepack well screens have two types. One type consists of two layers wedge wire
screens and the middle filter. The other type consist of perforated base pipe or slotted API casing pipe and outer screen jacket. The base pipe can be stainless steel or carbon steel API 5CT casing. Having the API casing inside a wire wrap screen jacket is supporting the screen and enhance the capabilities and high tensile strength Loads. Base pipe can be made from API pipe seamless casing spiral or stainless steel casing. Opening area for the base pipe is up to 15% and for the jacket is up to 30%. Johnson type jacket slot size is between 0.15mm to 3mm.
dvantages of Johnson type stainless steel prepack well screens
1. Higher filtering accuracy: all-welded wedge wire screens as screen jacket with vee opening design makes the filtering accuracy higher, which can control sand better.
2.Excellent strength and resistance to deformation: The base pipe inside, the outside can be protected with the protection jacket added according to requirements, the integrated strength of the perforated base pipe only decreases 2~3% compared with the standard casing/oil tubing, so the pipe based well screens have enough integrated strength to resist to the pressure caused by strata. Even if some part of the well screens deformed, the slot of this part will not be widened, which makes higher sand control reliability.
3.More choices: the material of screen jacket can be stainless steel or carbon steel, the material can be chosen as per customers’ requirement.
4.The excellent technique makes the mass production with high efficiency and low cost available.
5.The smaller slot will increase the oil and gas production especially in horizontal well.
