The output of shale oil in Jiangsu oilfield exceeds 50,000 tons

Jiangsu Oilfield actively promotes the strategy of developing both natural and natural resources, strengthens shale oil exploration and development, and achieves a breakthrough in oil and gas resources. As of July 28, the cumulative production of shale oil exceeded 50,000 tons.

They innovated a block-type shale oil fracture network fracturing technology system, thousands of meters underground in the fault block shale rock, pressure a "highway", so that shale oil hidden in tiny pores through the artificial fracture network into the wellbore.

In May this year, the shale oil well - Huaye 7HF well successfully completed 32 stages of fracturing, the vertical depth of more than 4,200 meters, the average sand intensity of more than 4.2 tons/meter, the fracturing vertical depth, the amount of sand added to a single well, the average sand intensity, and the total amount of carbon dioxide injected in Subei Basin, the highest 4 records. On June 9, the Huafye 7HF well used a 3mm oil nozzle to discharge the liquid, and saw a high-yield industrial oil flow.
