sand control screen

we can produce all kinds of screen pipes which is according to the horizental well

Screen pipe is a large size precision mipor sand-filtering tube, which owns great advantages, such as large filtering area, low flowed friction, strong block-preventing, high strength, long service life and so on. Adopting screen pipe for well-completion can protect oil-gas layer effectively, reduce the damage of formation largely during the process of well-completion; also it can ensure a clear connectivity between oil-gas layer and borehole to control sand flow of oil-gas layer effectively and prevent borehole wall collapse, which guarantees long-term production of oil-gas well. It is convenient for both well operation and sidetrack drilling during the later period of oilfield development. Cementing in kick-off section can stop upper water-layer effectively from flow-cross, also can protect upper production-casing. Meantime, it may adopt clean-out, acidating and expanding-containment to go on high-flow and reverse circulation clean-out of well with one trip run. For longer lever section or heterogeneous development formation, it can adopt external packer to product oil with sublevel method for formation and oil layer to improve recovery ratio of reservoir; adopting variable density fluidics can not only defer or inhibit sudden movement of bottom water but also relieve the pollution to oil layer during the process of drilling. Comparing to common well-completion, it can reduce cost largely.
