摘要：

珠江口盆地H油田主要发育三角洲前缘沉积,储层厚度薄、横向变化快,对岩性边界及砂体连通性的认识不清,严重制约了油田的高效开发。地震波形指示反演能够充分利用地震波形的横向变化信息建立井插值模型,井间预测能力较好,特别适合横向变化快、非均值性强、薄互层储层的高精度预测。而地震沉积学方法则是在等时地层格架指导下,利用地震属性切片对储层的横向展布特征进行精细刻画,对地质体沉积规律进行演绎,对于垂向上不可分辨的薄储层的平面沉积特征具有较好的检测效果。综合上述2种方法,形成了一套针对海相薄砂岩储层精细描述和沉积特征刻画的技术流程,并在H油田取得了良好的应用效果,为研究区剩余油预测和调整挖潜提供了有效的技术支撑。

Abstract:

H Oilfield in the Pearl River Mouth Basin mainly develops delta front deposits. Its reservoir thickness is thin, the lateral change is fast, and the understanding of lithologic boundary and sand body connectivity is not clear, which seriously restricts the efficient development of oil field. Seismic waveform indication inversion can fully use the lateral changes of seismic waveforms to carry out high-frequency component estimation, and establish the interpolation model which is more consistent with the sedimentary characteristics. This method has good inter-well prediction ability, and is particularly suitable for high-precision prediction of fast lateral changes, strong non-average, and thin interbedded sand and mudstone reservoirs. While for another method, seismic sedimentology, is to use the seismic attribute slice to describe the lateral distribution range and sedimentary characteristics of the reservoir under the guidance of isochronous stratigraphic framework. It has a good detection effect on the plane sedimentary characteristics of thin reservoir which cannot be resolved vertically. Combined with the above two methods, a set of technical processes for fine description and sedimentary characterization of marine thin sandstone reservoirs is formed and has achieved good application results in H Oilfield, meanwhile provides effective technical support for remaining oil prediction and potential tapping adjustment in the study area.

Key words: oilfield development, seismic waveform inversion, seismic sedimentology, reservoir prediction, seismic attribute
