中国海油在渤海发现秦皇岛27-3重大油田，新增探明石油当量超亿吨。

秦皇岛27-3油田位于渤海中北部海域，平均水深约25 m。主要含油层带为新近系明化镇组，油性为中稠油。

QHD27-3-3发现井完钻深度1570m，共钻遇油层48.9m。该油田经测试单口井每天可生产约 742 桶原油。通过持续勘探，秦皇岛27-3油田探明地质储量已达1.04亿吨油当量。

☆黄岛27-3油田是我们十年来在渤海中北部取得的又一个探明地质储量过亿吨的重大发现。“该油田的成功发现，进一步展现了渤海复杂走滑断裂带的油气勘探潜力。”中国海油勘探副总干事徐长贵表示。

CNOOC has made a major oilfield discovery of Qinhuangdao 27-3 in the Bohai Sea, adding over 100 million tons of oil equivalent proved in-place volume.

The Qinhuangdao 27-3 oilfield is located in the north-central waters of the Bohai Sea, with an average water depth of approximately 25 m. The main oil-bearing play is the Minghuazhen Formation of Neogene, and the oil property is medium-heavy crude.

The discovery well QHD27-3-3 was drilled and completed at a depth of 1,570 m, which encountered a total of 48.9 m oil pay zones. The field has been tested to produce approximately 742 barrels of crude oil per day from a single well. Through continued exploration, the proved in-place volume of Qinhuangdao 27-3 oilfield has reached 104 million tons of oil equivalent.

“Qinhuangdao 27-3 oilfield is another major discovery with proved-in-place volume over 100 million tons that we made in the north-central Bohai Sea in a decade. The successful discovery of the oilfield further demonstrates the oil and gas exploration potential in the complicated strike-slip fault zones of the Bohai Sea,” said Xu Changgui, Deputy Chief Exploration Officer of CNOOC.
