摘要
YB地区雷口坡组发育大型的岩溶气藏,其储层发育与中三叠统古风化壳岩溶地貌密切相关。这里结合勘探实践,从古地貌分析入手,研究储层发育的有利区,通过大量的钻井资料对研究区储层的物性特征、储集空间特征、测井响应特征,以及地震响应特征综合分析,明确了储层发育的控制因素。在此基础上开展了这种古风化壳岩溶储层的综合预测方法探索,识别出储层发育区。
The YB area Leikoupo formation developed the large-scale karst reservoir,the reservoir development is closely related to the ancient weathering crust karst topography in the Middle triassic.Combining the exploration practice,studying the favorable area of reservoir from the paleogeomorphology analysis,Through a large number of drilling data,comprehensively analyzing the physical properties,reservoir space characteristics,logging response characteristics and seismic response characteristics,the controlling factors of reservoir development is defined.The comprehensive prediction method exploration of the weathering crust karst reservoir is carried out based on the above analysis,and the development of reservoir is identified.
