Y-block separated production string and Y-block commingled production string are the common completion strings of ESP artificial lift. Y-block commingled production string configuration is simple and easy to be operated. Under the same pressure system and fluid property of all layers, all the layers can produce simultaneously. Y-block separated production string is suitable for separated production of single layer of multilayer zones, not to control commingled production or to contrl commingled production, it is commonly conducted by slick line operation.

Production Completion String of Gas Lift

Introduction:

Gas lift production has characteristics of large fluid rate, deep gas lift capacity, corrosion resistance, and easy operation and management, etc. It is suit for high ratio of fluid to gas, deep well, sand production well and deviated well. Gas lift production can form huge production drawdown within wellbore. It is an ideal method of carrying fluid, and can be a steady technology of oilfield development. In addition, the main equipment of production technology (compressor, etc.) is installed on ground, it is easy to check and maintain, less occupancy of deck area, and suitable for offshore oilfield.

Flowing Well Production Completion String

Introduction:

The production completion string of flowing well is simple, and it uses retrievable hydraulic –set production Packer. The tool material (include seal elements) has corrosion resistance in the consideration of detailed tool configuration. It is commonly used with high quality seal, special screw thread of metal to metal seal (such as FOX, NEW VAM, TS-3SB,HSM-2, etc.). Depending on the production requirements, its tool configuration can add chemical medicament injection valve, traveljoint, etc.
