Well Longping-1 is the first horizontal well drilled in the bedrock formation of Songliao Basin in Daqing Oilfield. The designed MD is 4532.72m (TVD: 3111.50m). The exploration purpose of the well is to explore how to greatly improve the natural gas productivity of the weathered crust bedrock reservoir in the ancient central uplift zone through horizontal wells. In order to tackle the potential difficulties and risks in the process of drilling, optimization was performed of well structure design, well trajectory design, drilling parameters, and bit selection with the ROP enhancement experiments. The full well average ROP was 5.15m/h with an significant increase by 45.89% compared with the designed value, which provides valuable experience for exploring the basal structure in this area.
