摘要: 根据对饶阳凹陷长洋淀潜山勘探实践的归纳总结,初步形成了一套针对深潜山的勘探思路:分析该区综合地质特征和复杂的油水关系,确定勘探目标;充分运用高精度三维地震采集技术和叠前时间偏移处理技术,提高地震资料的品质;精细地震资料解释,准确落实圈闭。对油源、储层、封盖条件进行综合评价,从而构建了一个新的成藏模式"新生古堵古储",以此落实了新的潜山圈闭——长3井潜山。经综合论证后设计钻探的长3井在雾迷山组获得高产油气流。

Abstract: According to the exploration in Changyangdian buried-hill of Raoyang sag, systematic ideas aiming at buried-hill exploration are developed preliminarily. Firstly, the comprehensive geological characteristics and complicated relationship between oil and water are analyzed, and exploration targets are determined. Then high-precision 3D seismic acquisition techniques and pre-stack migration processing techniques are fully utilized, and the quality of seismic data is improved. At last, accurate seismic data interpretation is made and accurate trapping is fulfilled. Based on the comprehensive evaluation on oil sources, reservoirs, and sealing conditions, a new accumulation model-new source, paleo sealing and reservoir formation- is developed. Finally a new buried-hill trap, i.e., the Chang 3 well buried hill is fulfilled. Plenty of oil and gas stream is obtained in Wumishan Formation.

Key words: Raoyang sag, Changyangdian, deep buried-hill, exploration technology
