Abstract:

This paper describes the principle of optimized tubing string for water drainage-oil recovery technology.Using the basic gas equation,particle mechanics and breaking mechanics of liqrid drop,we derive a mathematical model for continuous water drainage of a gas well and draw the solution nomograph as well.The research achievements are of great significance in increasing the ultimate recovery ratio.

Key words: Gas field development, Ultimate recovery ratio, tubing string optimization, Water drainage-oil recovery, Mathematical model, Nomograph
