Analysis on Ways to Stimulate the Oil Well by Using Systematic Thinking

On the basis of the concept that an oil well is a process production system, a systematic model is established, which involves the behavior of a pumping well flowing from drainage boundary to wellhead A dynamic simulation is carried out on 17 pumping wells in S block of Zhongyuan oilfield, and the result obtained is analyzed comprehensively The wells mentioned are classified into four categories: lower pumping efficiency, large additional pressure resulted from a completion interval, large pressure difference caused by formation damage at near wellbore and a less total additional pressure draw down Appropriate stimulations for different situations are proposed
