摘要

飞仙关组作为川东北地区的主力产气层,储集岩以鲕粒云岩为主,圈闭类型以构造-岩性复合圈闭为主。随着勘探开发的不断深化,飞仙关组鲕滩气藏圈闭识别问题变得十分突出。通过对成藏条件与分布规律的分析,开展了飞仙关组各沉积相对应的地震响应特征、鲕滩型储层的地震响应特征等地震相研究,从而对埋深较大、勘探程度相对较低的五宝场地区进行鲕滩储层分布预测,识别该区构造-岩性复合圈闭,指导五宝场地区鲕滩气藏的深化勘探。图4参5
Feixianguan Formation is the principal gas-producing interval in northeastern Sichuan Basin.And the reservoir is mainly composed by oolitic dolomite and its main trap type is structural-lithological compound trap.As a gradually further E & P,to identify the oolitic shoal gas reservoir of Feixianguan Formation trap becomes outstanding.In this paper,the reservoir-forming condition and reservoir distribution are analyzed;the seismic response characteristics of both different seismic facies and oolitic shoal reservoir are studied;the distribution of oolitic shoal reservoir in Wubaochang area is predicted even the reservoir is featured by large burial depth and relatively low exploration degree;and the structural-lithological compound trap is identified which can guide a further exploration for oolitic shoal gas reservoirs.
