摘要： 浅水三角洲薄砂层是重要的岩性油气藏勘探新领域，但砂体薄、横向变化快，沉积结构特征难以识别，制约了该类沉积体的勘探开发。以准噶尔盆地莫索湾凸起芳草湖地区为例，通过地质-地球物理综合分析，深化地震沉积学分析技术。采用“准层序组内高低频旋回波形分离技术”、“去除地层切片干涉效应技术”和“地质体与沉积背景属性融合技术”等3项技术，开展了浅水三角洲地震沉积学特征研究，并总结了浅水曲流河三角洲沉积模式。研究表明：①白垩系清水河组一段发育多个四级层序，反映湖平面周期性变化；②下切水道、扇状砂体广泛发育；③白垩系清水河一段浅水曲流河三角洲沉积体系发育3套储盖组合，是潜力较大的勘探层系。浅水三角洲薄砂层地震沉积特征识别技术的应用，助推了风险井位上钻，并取得较好的勘探效果，为该区增储上产提供了技术保障，同时对其他类似地区的薄砂层识别具有较好的借鉴意义。

Abstract: Shallow water delta thin sand layer is an important new field of lithologic reservoir exploration. It is difficult to identify the sedimentary structure of shallow water delta due to thin sand bodies and rapid lateral variation,which restricts the exploration and development of this kind of sedimentary body. Taking Fangcaohu area of Mosuowan uplift in Junggar Basin as an example,the seismic sedimentological analysis technology was deepened through comprehensive geological and geophysical analysis. The seismic sedimentological characteristics of shallow water deltas were studied,and the sedimentary models of shallow water meandering river deltas were summarized by using three technologies, such as high and low frequency cycle waveform separation in parasequence set, remov-ing interference effect of stratigraphic slice and attribute fusion of geological body and sedimentary background. The results show that:(1) Multiple fourth-order sequences are developed in the first member of Cretaceous Qingshuihe Formation in Fangcaohu area,reflecting the periodic change of lake level.(2) Incised channels and fanshaped sand bodies are widely developed.(3) There are three sets of reservoir-cap assemblages developed in the shallow meandering river delta sedimentary system of the first member of Cretaceous Qingshuihe Formation, which are exploration strata with great potential in this area. The application of seismic sedimentary characteristics identification technology of thin sand layers in shallow water deltas has promoted the drilling of risk wells and achieved good exploration results. This technology provides technical support for increasing reserves and production in this area, and it can provide reference for the identification of thin sand layers in other similar areas.

Key words: seismic sedimentology, undercut channel, waveform separation, de-interference effect, attribute fusion, Qingshuihe Formation, Mosuowan uplift, Junggar Basin
