川东北双庙场构造嘉二段储层综合预测
|
摘要
双庙场构造嘉二段储层以白云岩储层为主;白云岩储层物性较好,主要为裂缝孔隙型储层,储集空间主要为晶间溶孔、裂缝.文中根据构造应力场理论、地震波频率衰减及裂缝检测理论,运用构造应力场数值模拟分析、裂缝各向异性属性分析、FVO分析、叠前弹性波阻抗反演及衰减属性分析等方法,充分利用现有的地质、钻井、测井资料和叠前、叠后地震数据,对双庙场构造嘉二段储层开展联合预测,搞清了裂缝发育与地层岩性、应力分布以及构造发育之间的关系,明确了裂缝的走向、密度及白云岩有利储层发育部位,预测了有利储层的分布范围.实际资料应用表明,用该套方法识别裂缝孔隙型储层是有效和可靠的,可以检测出有利的储层发育带.
The Jia-2 member of Shuang Miao structure is a dolomite-dominated reservoir.This kind of dolomite reservoirs shows characteristics of good physical properties including fracture-pore type and reservoir space of intercrystalline solution pores and fractures.Based on the theory of tectonic stress field,seismic frequency attenuation and fracture detection,this paper has done researches on unified prediction of the Jia-2 reservoir that has applied a series of metods including numerical modelling of the tectonic stress field,fracture anisotropy,FVO,prestack elastic inversion and attenuation attributes by thoroughly utilizing available data of geology,well-drilling,well log and seismic data of prestack&poststack.Not only the predication result has revealed the strike and density of fractures, the relationship among formation lithology,stress distribution and tectonic development,but also are forcasted the locations of favorable dolomite reservoir as well as favorable reservoir distribution ranges.Practice has proved that these methods are effective and reliable,and can be applied to the recognization of favorable zones in the fracture-pore reservoirs.
