On February 22nd, it was learned from Southwest Oil and Gas Field Company that the drilling of Well 201H8-9 was successfully completed, with a drilling cycle of 64.4 days, of which the fourth drilling cycle was 13.6 days. At the same time, it broke the record for the shortest drilling cycle in the Yuxi block and the fourth drilling cycle in the Zu201 block, achieving a significant breakthrough in the efficiency of deep shale gas drilling operations.
Based on historical well seismic data, combined with real-time corrected geophysical data, fine crack prediction is carried out to accurately identify the “double sweet spots” of geological engineering. Within the “platinum target”, targets with high mechanical drilling speed and low rotational vibration are selected, and the wellbore trajectory is precisely controlled to be smooth; Select high-quality rotary guide tools and attack PDC bits with strong stability, monitor the equivalent density and friction coefficient at the bottom of the well in real time, monitor the cleanliness of the wellbore, reduce complex accidents, and ensure drilling safety. Continuously optimizing the operation processes of connecting columns, issuing instructions, and circulating cooling, scientifically reducing the density of drilling fluid, significantly improving the efficiency of pure drilling, and laying a solid foundation for improving drilling speed and efficiency.
