中国海洋石油渤海公司曹妃甸1-6油田已于1995年5月建成投产,开始直接向天津乙烯工程供油.该油田估算高峰年产量可达31万t,预计生产期限为5年.曹妃甸l-6花岗岩潜山油藏含油面积1.7km~(2),地质储量900万t,为一典型的孤立小油田.该油田的井口平台为一经过改造的可移动式旧钻井平台,利用已停产的渤中28-1的“友谊号”浮式储油轮作为储油装置.利用旧设施投产新油田,这在中国海洋石油总公司尚属首次.曹妃甸l-6油田的发现和建成投产开拓了在花岗岩中找油气的新领域,为海洋石油开发类似的孤立小油田展示了美好前景.
China National Offshore Oil Bohai Company Caofeidian 1-6 oilfield has been put into operation in May 1995, began to supply ethylene directly to the Tianjin ethylene project. The oilfield estimates peak annual output up to 310,000 t, the expected production period of 5 years. Caofeidian l- 6 The granite buried hill reservoir has an oil-bearing area of 1.7km ~ (2) and a geological reserve of 9,000,000 t, and is a typical orphan oilfield. The wellhead platform of this oilfield is a remodeled movable old drilling platform, Bozhong 28-1 “Friendship” floating oil tanker as an oil storage device. The use of old facilities to put into operation a new oil field, which is the first time for China National Offshore Oil Corporation is the discovery of Caofeidian l-6 oil field and put into operation opened up in New areas for hydrocarbon discovery in granites have shown promising prospects for offshore oil-like orphaned oil fields.
