塔中北斜坡鹰山组碳酸盐岩缝洞储集层预测及成藏规律
|
摘要
运用多种储集层预测技术对塔中地区鹰山组风化壳缝洞储集层纵横向分布进行预测和成图,并利用AVO油气检测技术对缝洞内流体性质进行判断。坚持处理-解释-地质一体化的工作模式,建立各种井控储集层地质模型,明确高产井有利储集体地震响应特征。利用大量的地震信息,预测无井区的储集层及油气分布,结合古地貌、露头岩性、缝洞储集层的连续性及后期断裂的切割关系划分缝洞系统及单元,根据实钻井试油成果确定缝洞单元内的油水界面,总结探讨区域油气分布规律。
Many reservoir prediction technologies are used for prediction and mapping of Yingshan fractured-vuggy reservoirs' vertical and lateral distributions in Tazhong area,and AVO oil-gas detection technology is applied to adjustment of the fluid property within fractures and caves.Integrating with processing,interpretation and geology,the various well-control reservoir geologic models are developed.The seismic response features of favorable reservoir bodies in high-yielding wells are given.Lots of the seismic information are used to predict reservoirs and hydrocarbon distribution in no well-drilling areas.The fracture and cave system and units are classified combining with palaeo-geomorphology,outcrop lithology,continuity of fractured-vuggy reservoir and later faulting cutting relations.Finally,the water-oil interfaces in fracture and cave units are determined according to drilling and formation test results,and the regional petroleum distribution is discussed and summarized.
