On October 24, the "Shunbei 53-2h well" in Northwest Oilfield was successfully drilled with a depth of 8874.4 meters, setting a record for the deepest directional well in Asia, 29.97 meters higher than the world's highest peak, Everest.This also broke the Asian well depth record of 8725 meters set by "Shunbei 55x well" three months ago.
It is reported that both records are from team 80117 of Sinopec Shengli Petroleum Engineering Company Tarim branch.
"Shunbei 53-2h well" is a four opening evaluation horizontal well in shuntogole low uplift area of Shunbei block in the hinterland of Taklimakan Desert. The original design depth of well is 8338m, and it is deepened to 8874.4m according to the geological needs.
Shunbei area is one of the deepest onshore oil and gas fields in Asia. There is no relevant technology and experience to learn from at home and abroadThe underground geological conditions are complex and the drillability is very poor; the fourth spud drilling has serious downhole leakage; the bottom hole pressure is high and the well control risk is high.
next step,The team will challenge the depth of 9000 meters in Shunbei block, continue to refresh the record.
