Sinopec News Network reported on September 22 that the Jiaoye 85-S2HF well constructed by the 50753 Drilling Team of the Second Drilling Company of Zhongyuan Petroleum Engineering Company was under construction.
A single drill bit passed through the Feixianguan Formation, Changxing Formation, and Longtan Formation.
Drilling to the upper part of the Maokou Formation is 289 meters, the footage is 919 meters, the pure drilling time is 52 hours, and the ROP is 17.
67 meters per hour, which greatly breaks the new record of 311.
2 mm ROP in the Jiaoshiba block
.
The Jiaoye 85-S2HF well is a development well deployed by Jianghan Petroleum and Natural Gas Co.
, Ltd.
in the Jiaoshiba area
.
Since the start of drilling, the team has vigorously promoted the "four lifts" work and established a rapid drilling technology research team to ensure the normal progress of underground construction operations from three aspects: engineering technology, environmental protection and safety, and equipment operation
At the same time, the team took the "five inspections and five stricts" special action as an opportunity to strengthen daily safety inspections, early detection and early treatment of equipment problems, and strengthened inspections on key and vital parts to reduce drilling timeliness caused by equipment maintenance.

The Jiaoye 85 platform is a well factory model drilling platform.
Prior to this, the 85 platform has produced 8 wells.
The upper shallow gas is very active, and it is easy to leak and collapse
.
The team uses an anti-collapse drilling fluid system and maintains a high viscosity of the drilling fluid.
