Design of a high-performance pressure-preserving controller for in situ pressure-preserving coring in deep oil and gas extraction

Pressure-preserving controllers (PPCs) are crucial components of in situ pressure-preserving coring (IPP-Coring) devices for deep oil and gas extraction, and their ultimate pressure-bearing (UPB) capability determines the upper limit of their ability to acquire oil and gas reserves. However, due to...
