阿布卡依克油田为沙特阿拉伯第二大油田,位于沙特阿拉伯东部,于1940年发现。阿布卡依克油田分为 A 区和 B 区两部份。A 区于1946年先投入开发,B 区于1950年才投入开发。油田投产后,由于高的开采速度,使油田地层压力迅速下降至饱和压力以下,形成次生气顶。因此,A 区于1954年开始采用顶部注气,B 区于1956年采用边外注水保持压力开发。随后,A 区也采用了边外注水开发。
Abkhazqueh oil field is Saudi Arabia’s second largest oil field, located in eastern Saudi Arabia, discovered in 1940. Abkhaz field is divided into two parts A and B area. Area A was first put into development in 1946, and Area B was put into development in 1950. After the oilfield is put into operation, due to the high exploitation rate, the formation pressure in the oilfield rapidly drops below the saturation pressure, forming a secondary gas cap. As a result, Area A started to inject gas at the top in 1954 and Area B in 1956 to maintain the pressure by using extra-lateral water. Subsequently, Area A also used outside the water injection development.
