摘　　要：塔河油田A区位于塔北隆起带阿克库勒凸起中。该区域奥陶系海相碳酸盐地层由于经历了加里东与海西两期大的构造运动,发育形成了一些列埋藏较深,非均质性较强的缝洞体系。针对这种特点,以约束稀疏脉冲反演为核心技术,综合运用地震、测井和地质资料,重点分析针对碳酸盐岩缝洞体储层的子波提取、井震标定、地质模型建立等关键技术环节。通过研究识别了研究区致密碳酸盐岩顶部风化壳和内幕缝洞体结构,并指出该方法应用的局限性。The area A of tahe oilfield is located in the akkule uplift of north tahe uplift belt.The ordovician Marine carbonate strata in this region developed a series of cavern systems which is deep-buried and highly heterogeneous fracture due to the two major tectonic movements of caledonian and hercynian.For the characteristic mentioned above,the basic process of constrained sparse pulse inversion with Jason software as the platform,integrated use of seismic,logging data,to solve the key problems such as wavelet extraction,well calibration,establishing geological model.The results show that:Constrained sparse pulse inversion results have good corresponding relationship with seismic reflection data characteristics,accurately recognizing the weathered crust at the top of the Ordovician carbonate and the successful prediction of cave body,meanwhile,point out the boundedness of this retrieval method.
