Paper presented at the International Petroleum Technology Conference, March 23–April 1, 2021
Paper Number: IPTC-21362-MS
... Abstract In view of the high shut in pressure of gas wells in Kuqa mountain front ultra-high pressure block where the highest shut in pressure of KeS X is 115MPa, the 105MPa casing head currently used can not meet the shut in demanding, so the risk of well control is high. A new 140MPa mandrel...
