PETROCHINA(SH:601857) Zhong Guo Xin Wen Wang·2025-06-17 15:09Core Insights - The successful trial production of the Yingye 1H well in the Dongyue Temple section has resulted in high industrial oil and gas flow, achieving a daily production of 8 tons of oil and 30,000 cubic meters of natural gas, providing new momentum for the Daqing Oilfield's exploration and production in the Sichuan-Chongqing area [1][2] Group 1: Production and Exploration - The Yingye 1H well demonstrated significant oil and gas invasion and large fracturing scale during drilling, although the well's low formation pressure led to suboptimal trial production results, keeping it in a shut-in state [1] - The Daqing Oilfield's second oil production plant has not abandoned the exploration of this well, emphasizing the importance of geological understanding of the undeveloped layers in the Dongyue Temple section [1] Group 2: Technical Improvements and Management Strategies - The company has conducted extensive technical research, analyzing drilling core data, trial production dynamics, and pressure measurement data, concluding that the well's reservoir is well-developed, and the short trial gas time and low recovery rate were the main reasons for the initial underperformance [1] - The Daqing Oilfield's second oil production plant has implemented differentiated management strategies to enhance oil and gas production, including optimizing production systems and managing scattered gas production rates, resulting in an additional 399 million cubic meters of gas from 16 optimization adjustments [2] Group 3: Revival of Idle Wells - The company is exploring strategies for the revival of long-idled wells by collecting and analyzing seismic, logging, drilling, and production data, and has developed geological plans for the revival of 8 wells, with the first batch of 4 wells expected to be implemented in the second half of the year [2]
