摘要: 微幅度构造是油田开发中注水未波及的剩余油富集区。X105区块井间存在井网难以控制的微幅度构造,由于规模小,地震识别难。为提高识别精度,从3个方面开展了技术对策研究,以提高基础数据的准确性:开展提高微幅度构造成像精度的地震振幅高保真处理;创新了相位体约束层位解释方法提高砂岩组顶面识别精度;利用厚砂体井震匹配矛盾、"深浅"井震匹配矛盾分析法对微幅度构造进行筛选,去伪存真。应用上述方法,砂岩组顶面识别出断层控制和非断层控制两种成因类型的微幅度构造。在微幅度构造发育部位优选出未波及型和完善注采关系型两类剩余油挖潜区域,部署补充井实现了剩余油有效动用。

Abstract: The micro-amplitude structure is a remaining oil-enriched area that has not been affected by water injection in oilfield development. The micro-amplitude structure in X105 Block is well-developed. Because of its small scale, it is difficult to identify with seismic data. In order to improve the accuracy of micro-amplitude structure recognition, the author of this paper conducts technical research on three aspects to improve the accuracy of basic data. The first is to develop high-fidelity processing of seismic amplitude by improving the imaging precision of micro-amplitude structure. The second is to innovate the method of horizon interpretation of phase-constraints, which improves the interpretation accuracy of the top interface of sandstone formations. Thirdly, "contradiction between deep and shallow stratum" and other well-quake matching relationships are used to screen the micro-magnitude structure and eliminate the false. The above methods can be used to re-recognize the characteristics of the micro-amplitude structural development and guide the development of remaining oil.

Key words: X105 Block, micro-amplitude structure, phase body constraint, well-shake matching contradiction, high fidelity
