摘要
以渤中凹陷西次洼427地区西部陡坡带为主,开展了石南陡坡带高精度层序地层格架下的沉积体系研究和岩性圈闭识别研究。研究发现,渤中凹陷西次洼427地区西部陡坡带东营组发育3个4～5级基准面旋回,基准面旋回控制砂体发育,地震相、地震属性和地震反演均表明,基准面上升旋回的下部是砂体发育的有利位置,砂体富集,每期砂体向西尖灭,形成岩性侧向尖灭型岩性圈闭,且每期旋回形成的岩性圈闭叠合性好。该岩性圈闭通过勘探实践获得了巨大成功,对渤海海域其他类似地区的岩性勘探提供了重要的借鉴。
According to the comprehensive analysis of seismic and logging data,high-resolution sequence stratigraphy and lithological traps in sequence framework were researched in Dongying Formation of the 427 slope in Bozhong Sag. The results show that there are three base-level cycles of 4-5 order sequence in Dongying Formation. Sandstone reservoirs control the base-level cycle. Sandstone reservoirs with relatively good properties occurrs mainly in the lower of the base-level rise cycle,which is pinch-out from east to west and form lithological traps. Multi-stage lithological traps overlay vertically. The lithologic trap obtains the thremendous success through exploration practice,lithological exploration of other similar in the Bohai Region offers an important reference.
