海月东坡-盖州滩断裂带油藏特征及油气检测

Reservoir Characteristics and Oil and Gas Detection of the Eastem Slope of Haiyue-Gaizhoutan Fault Zone

为了尽快在海月东坡-盖州滩断裂带形成规模储量,开展了油藏特征分析以及油气检测技术的应用,明确了区内油气成藏特点及分布规律,为井位部署提供了依据。研究表明,盖州滩断鼻构造带以构造油气藏为主,海月东坡以地层-岩性油气藏为主,主要目的层为东营组二、三段和沙河街组一、三段,自盖州滩断鼻到海月斜坡含油气层位逐渐变老,且由气层为主转为油层为主;海月东坡和盖州滩断鼻构造带均是有利的油气富集区。

In order to form large-scale reserves in the eastem slope of Haiyue-Gaizhou beach fault zone as soon as possible,the reservoir characteristics analysis and the application of oil and gas detection technology were carried out,and the characteristics and distribution law of oil and gas accumulation in the area were clarified,which provides a basis for well location deployment.The study shows that the fault nose of Gaizhou beach is dominated by structural oil and gas reservoirs,while the eastem slope of Haiyue is dominated by stratigraphic-lithologic oil and gas reservoirs.The main target layers are the 2nd and 3rd members of Dongying Formation and the 1st and 3rd members of Shahejie Formation.From the fault nose of Gaizhou beach to Haiyue slope,the oil and gas bearing horizons have gradually become older and have changed from gas to oil.Both the eastem slope of Haiyue and Gaizhoutan fault nose structural belt are favorable oil and gas enrichment areas.
