摘要
运用岩心及地层微电阻率扫描成像(FMI)测井资料、常规测井资料、声波时差分形分析及地震资料蚂蚁体追踪裂缝检测技术对百21井区夏子街组二段(P2x2)储层裂缝进行了识别。岩心及FMI测井资料表明,P2x2裂缝产状可分2组,为典型的剪切裂缝;常规测井响应特征可定性反映不同类型裂缝的发育程度,声波时差分形分析识别的裂缝发育段与试油结论基本符合;地震资料蚂蚁体追踪裂缝检测结果显示,P2x2主要存在北西向裂缝发育带和正北向裂缝发育带,且第四小层裂缝发育程度较第三小层高,其识别的裂缝发育段与试油结果中的产油、产水段也基本符合。声波时差分形分析与地震资料蚂蚁体追踪裂缝检测识别的裂缝发育段比较可靠。
By using core data and data of formation micro-resistivity imaging logging,conventional logging data,the fractal analysis of acoustic transit time and ant body tracking for fractural detection,the reservoir fractures in the second member of Xiazijie Formation(P2x)in Wellblock Bai 21were identified.Core and FMI logging data show that the fractures of P2x are typical shear fractures,which can be classified into two groups of occurrences.Conventional logging response characteristics can be demonstrated as the degree of qualitative development of fractures.And the fractural detection results by the method of fractal analysis of acoustic transit time are consistent with the oil testing conclusion.According to ant body tracking of seismic data,the fracture intervals of P2x are mainly developed in NW and N directions,and fractures are more developed in the 4th member that that in the 3rd member.Also,the fracture intervals identified by ant body tracking is matched with oil production and water production zones.The fracture detection technology of fractal analysis of acoustic transit time and ant body tracking of seismic data are reliable.
