Pipe Based Screens                                                                                                                                                               Company Profile:
Oasis Oil Tools Co.,LTD, located in the industrial park of high-tech enterprises in Fengquan District, Xinxiang City, covers more than 20000 square meters with total RMB 15 million investment. Oasis now has more than 150 staff, among them 6 persons are senior engineer. After many years’ efforts, now OASIS has developed into a  professional and famous manufacturer, which design, manufacture and sell water well screens/johnson screens, oil well screens and sand control well screens, bridge slotted well screens, pipe based well screens, perforated pipe (base pipe), gravel pre-packed well screens, wedge wire screens,  passive water intake screens etc. water, oil and gas well filtering products as well steel tubes and pipes and industrial parts.
The pipe base screens are used for deep water well application and oil field application. It is used for sand control in wells with high pressure and high traction value due to the depths. Pipe based well screens consist of base pipe, all-welded wedge wire screen and supporting rod. The base pipe is perforated or slotted API casing pipe. The base pipe can be stainless steel or carbon steel API 5CT casing. The all-welded wedge wire screens are welded together with base pipe by supporting rod.Having the API casing inside a wire wrap screen jacket is supporting the screen and enhance the cabapities and high tensile strength Loads. Pipe base 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%. Jacket slot size is between 0.15mm to 3mm.

Features of pipe based screens
Higher filtering accuracy. All-welded wedge wire screens as screen jacket with V 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 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’ requirements.
4. The excellent technique makes the mass production with high efficiency and low cost available.
