Safe drilling technology for ultra-deep gas wells with complex pressure systems using managed pressure and gas-venting density reduction
Marine carbonate oil and gas resources in the western Sichuan region of the Sichuan Basin are buried at depths exceeding 7 000 meters. Vertically, multiple hydrocarbon reservoirs exist, resulting in complex pressure systems where the coexistence of influx and loss may occur within the same open hole...
