In oil production engineering, layered gas production is an important mining technology. While the interlayer pressure of natural gas well differs big, the interlayer interference forms. It is difficult to exploit the low pressure layer and control the high pressure layer. Developing a technical pipe string with integrating layered gas production can solve the above problems. This technical pipe string changes throttling area by striking, solves the conflicts between each layer, mines each layer uniformly and enhances recovery. It applied to Tai 4-28 gas well in Sebei-gas-field which is located in east of Qaidam basin perfects the 4th department of shallow layer well pattern, forms new capacity, controls each layer pressure and capacity smoothly, protects the reservoirs effectively, achieves good effect in practice.
