Abstract:

结合高品质地震资料，提出了歧口凹陷友谊地区受友谊走滑调节带控制，形成了大型褶曲断鼻构造，与南侧埕宁隆起物源控制的砂体带匹配良好，构成复式油气聚集带。深化调节带断裂砂体对油气成藏控制作用分析尤为重要，可提高勘探成功率，实现老油区新发展。
The high quality seismic data indicated that Youyi Area in Qikou Depression was controlled by strike-slip regulation, thus a large folded fault-nose structure was formed. It matched well with the sand belt controlled by the provenance of Chengning Uplift on the south side and developed a compound hydrocarbon accumulation zone. It is especially important for a deepening regulation of fault sand on the control of hydrocarbon accumulation for the purposes of improving the success rate of oil exploration and achieving the new development of old oilfields.
