P-WAVE AZIMUTHAL AVO ANALYSIS AND ITS APPLICATIONS TO LH11-1 OIL FIELD FOR FRACTURE DETECTION

摘要: LH11-1油田是我国近海最大的生物礁滩油田,受台地多期演化及后期成岩改造作用的影响,其碳酸盐岩储层物性横向变化大,非均质性强,由裂缝引起的各向异性特征明显。为了尽可能获得储层内裂缝的发育程度和分布情况,以叠前高分辨率三维地震资料为基础,利用P波方位AVO技术,通过正演找出最能反映流花地区碳酸盐岩裂缝发育情况的属性,预测了其储层裂缝的分布。

Abstract: The LH11-1 oil field is the biggest offshore bioherm (biobank) oil field of China. The carbonate platform has suffered multi-phase evolution and diagenesis. The physical properties of the carbonate reservoirs change drastically in lateral direction, showing a strong heterogeneity, which is obviously controlled by fracture systems. In order to acquire more information about the development of fractures and their distribution pattern as detail as possible, the method of P-wave azimuthal AVO based on high resolution 3D seismic data are applied in the carbonate reservoirs of Liu Hua oil field to finding out the most sensitive seismic properties for fracture detection, and distribution pattern prediction.
