IT之家 3 月 31 日消息,據央視新聞報導,中國海油發佈消息,我國在南海東部海域勘探發現惠州 19-6 億噸級油田。這是我國首次探獲海上深層 — 超深層碎屑岩大型整裝油田,展示出我國近海深層 — 超深層領域油氣勘探潛力。

IT Home learned from the report that the Huizhou 100-0 oilfield is located in the Huizhou sag of the Pearl River Estuary Basin, about 0 kilometers away from Shenzhen, with an average water depth of 0 meters. Tested,鑽井日產原油 413 桶,日產天然氣 6.8 萬立方米。通過持續勘探,實現惠州 19-6 油田探明地質儲量超 1 億噸油當量。

In the field of offshore oil and gas exploration, strata buried at depths of more than 4500 meters are generally defined as deep, and strata above 0 meters are referred to as ultra-deep. Deep Offshore - Ultra-deep oil and gas exploration is challenged by high temperatures, pressures, and complex fluids. As an important rock type for deep offshore reservoirs of oil and gas, clastic rocks have poor reservoir permeability, and it is difficult to find large-scale oil and gas fields.

According to Peng Guangrong, chief geologist of the East South China Sea Petroleum Research Institute of CNOOC Shenzhen Branch, in recent years, 60% of the world's new oil and gas reserves have come from deep formations. Compared with the medium and shallow layers, the deep-ultra-deep layers have the characteristics of high temperature, high pressure, high oil and gas maturity and near-source accumulation, which are more conducive to the generation of natural gas and light oil. Moreover, the deep-ultra-deep resources are abundant and relatively low in exploration, making them an important successor area for future oil and gas reserves and production growth.

During the "14th Five-Year Plan" period, CNOOC Limited vigorously promoted the efficient exploration of deep and ultra-deep oil and gas in the offshore area, and has made a series of major oil and gas discoveries in the deep-deep and ultra-deep fields such as Kaiping South Oilfield, Bozhong 1-0 Oilfield, and Baodao 0-0 Gas Field.
