Calculation Model for Adhesion Resistance in Differential Pressure Sticking of Downhole String

Calculation Model for Adhesion Resistance in Differential Pressure Sticking of Downhole String

Differential pressure sticking is one of the main causes for significantly increased non-production time and cost.The existing research on differential pressure sticking often relies on empirical summaries of field da-ta or laboratory tests，while the current theoretical model research also fails to...
