Shengli Oilfield shale oil achieves a strategic breakthrough in the first batch of predicted reserves of 458 million tons

The reporter learned from Sinopec Shengli Oilfield that the Jiyang shale oil exploration of Shengli Oilfield has blossomed at many points, and the first batch of forecasted oil reserves of 458 million tons has been fully explored and developed

As of October 28, Shengli Oilfield has drilled 4 special exploration wells for shale oil.

It is understood that the burial depth of Jiyang shale oil in Shengli Oilfield is more than 3,000 meters, and some shale oil and gas reservoirs are more than 4,000 meters deep, and the underground temperature exceeds 170℃.

At the Shengli Oilfield Exploration and Development Research Institute, the reporter saw a sample of shale oil extracted from more than 3,000 meters underground: a small half bottle of black crude oil was contained in a transparent glass bottle, and the crude oil could not flow when the bottle was turned upside down

According to Wang Xuejun, a senior expert in Shengli Oilfield, for more than 10 years, scientific and technological workers have been committed to tackling key problems, innovating and establishing a shale oil accumulation and enrichment model in continental faulted basins, developing shale oil breakthrough target optimization evaluation technology, and uncovering shale oil The true face of the "hiding place"; research and development of excellent and fast drilling technology, which allows horizontal wells with a horizontal section of more than 2000 meters to be drilled efficiently below 3,300 meters; the formation of fracture network fracturing technology allows shale oil to be manufactured in millimeters artificially It flows out on the “highway”, which greatly improves the productivity of a single well
