摘要:
渤海西南部A构造夹持在渤中凹陷主洼和西南次洼之间,成藏条件优越。但由于钻前含油气性指示不明,影响了井位部署,导致该区勘探进展缓慢。常规地球物理方法研究往往基于叠后地震成果资料,而叠后地震资料本身丢失了与含流体性质息息相关的AVO、横波、密度等信息,导致检测效果不理想。本文从叠前CRP道集出发,多方位挖掘地震资料隐含的流体信息,开展了常规地震内部属性提取、叠前地震AVO属性分析、叠前地震弹性参数求取、电阻率反演,并优选出含油气性敏感参数,建立了多层面关系,预测了含水饱和度体。最终利用优选出的参数进行了含油气性地震多参数综合检测,并形成了地震多参数综合含油气检测技术。该技术在A构造应用效果较好,成功指导了井位部署,助推了该区油气重大发现,同时为渤海其他类似构造提供了技术借鉴。
Abstract:
The A structure in the southwestern Bohai sea is included by the main sub-sag and the southwest sub-sag of Bozhong Sag, and its reservoir-forming conditions are excellent. However, the deployment of well locations was hindered by the uncertain pre-drilling oil and gas-bearing indicators, which results in slow exploration progress in this area. The conventional geophysical methods are often based on the poststack seismic data, and the poststack seismic data itself is absent of information that is closely related to fluids-bearing properties, such as AVO, shear waves and density, which leads to an unsatisfied detection effect. Starting from the prestack CRP gather, by virtue of multi-directional exploring the fluids information hidden in seismic data, this paper carried out the conventional seismic internal attributes extraction, prestack seismic AVO attribute analysis, prestack seismic elastic parameter determination and resistivity inversion, optimized the oil/gas-bearing sensitivity parameters, established a multi-level relationship, and predicted the water saturation body. Finally, the comprehensive multi-parameter seismic oil and gas detection was carried out by using the optimized parameters, and a multi-parameter comprehensive oil/gas-bearing seismic detection technology was formed. This technology has achieved a good application effect in structure A, which successfully guided the deployment of well locations, promoted the major oil and gas discoveries in this area, and provided technical references for exploring the other similar structures in the Bohai sea.
