渤深6潜山带油气藏特征的研究
|
摘要
渤深6井钻探发现了富集高产的下古生界潜山油藏,地震、钻井和成像测井资料研究表明,渤深6潜山带油气藏类型主要有潜山风化壳型和内幕型两类,储集空间以裂缝、溶洞为主。对渤深6潜山带的地层结构和构造特征以及成藏条件进行了分析研究,结果表明,该区下古生界油源充足,运移通道畅通,储层条件良好,是油气聚集的有利区块。对油气分布特点的分析表明,该区油气富集程度受距离油源的远近所控制,因此紧邻油源的潜山断块最具勘探潜力。
A rich and prolific reservoir was discovered in the lower Paleozoic buried hill during drilling well Boshen 6. Study of seismic, drilling, and logging data showed that the Boshen 6 buried hill reservoir can be divided into two types: weathering crust and hill-inside, their reservoir spaces were mainly fractures and caverns. This paper studied the stratal configuration, structural features, and reservoir-forming condition of the Boshen 6 buried hill belt. It was concluded that the lower Paleozoic buried hill was of rich oil source supply, free migration pathway, and favorable reservoir conditions, therefore was a favorable prospect of hydrocarbon concentration. The hydrocarbon concentration varied with the distance from oil sources, which indicated that the buried hill fault blocks near the oil sources were the most potential targets.
