The key exploratory well of Sinopec Northwest Oilfield, Shunbei 42X well, obtained high-yield industrial oil and gas, with a daily gas output of 822,000 cubic meters, a daily output of 300 tons of oil, and an oil and gas equivalent of nearly 1,000 tons. It is the first time to achieve a major oil and gas breakthrough in the exploration of the No. 4 fault zone in the Shunbei Oil and Gas Field. The preliminary estimate of the resource scale is over 100 million tons. This clarifies the resource pattern of natural gas in the east of the Shunbei Oil and Gas field and crude oil in the west. The construction of a 10-million-ton-level oil and gas field in 2022 will lay a solid resource foundation.
In recent years, Northwest Oilfield has continued to emancipate the mind, explore boldly, innovate understanding, and innovate technology. In geophysical prospecting, the integration of acquisition, processing and interpretation was implemented to accelerate the implementation and evaluation of targets, independently innovate the "three-layer and one-zone" stereo imaging technology and seismic signal absorption compensation technology, finely portray the three-dimensional characteristics of the 8000-meter underground fault zone, and strengthen the prediction and target of large-scale reservoirs Evaluation. Geologically, deepen the understanding of reservoir characteristics and enrichment laws, optimize well trajectory design, summarize the "two controls, three fixes and four types" well layout method in Shunbei reservoirs, and strive to achieve high production with few wells. In terms of engineering, we have carried out integrated geological engineering research, continuously optimized well structure, innovated and optimized drilling technology, and strived to improve quality, speed and efficiency.
The Shunbei area of ??the Tarim Basin has unique types of oil and gas reservoirs, with an average burial depth of more than 7,300 meters, making it one of the deepest oil reservoirs in the world. Prior to this, the Northwest Oilfield had built a million-ton production capacity in the Shunbei Oilfield. During the "14th Five-Year Plan" period, the Northwest Oilfield will simultaneously conduct large-scale exploration in the Shunbei Oil Region and the Shunbei Gas Region to achieve the goal of basically probing the Shunbei Oil Region and controlling the Shunbei Gas Region as a whole.
