罗家寨气田飞仙关组储层测井评价

罗家寨气田由罗家寨构造和磙子坪构造组成,是四川东北部地区的主力气田,三叠系飞仙关组是四川盆地继石炭系后最优质的接替储层,在勘探初期对该构造就采用先进设备获得了大量优良的常规和成像测井资料,基于这些测井资料,对罗家寨气田的储层划分标准、流体性质判别和单井产能预测等方面进行了深入分析,认为:罗家寨气田飞仙关组储层为白云岩溶孔-溶洞型鲕滩储层,储集空间包括多种孔隙喉道、溶洞和裂缝,罗家寨构造属孔隙型储层,磙子坪构造为裂缝-孔隙型储层.为罗家寨气田进一步的开发提供了依据.

RESERVOIR LOGGING EVALUATION OF FEIXIANGUAN FORMATION IN LUOJIAZHAI GAS FIELD

Luojiazhai gas field is composed of Luojiazhai structure and Gunziping structure, and is the most important gas field in northeast Sichuan. Feixianguan Formation reservoir in Triassic is the best carboniferous successor in Sichuan basin. On the initial exploration, a lot of excellent image logging data and regular logging data are obtained . The following conclusions are obtained based on analysis of the criteria for the classification of the reservoir, fluid properties of discrimination and single well productivity forecast, i. e, Feixianguan Formation reservoirs are dolomite Karst pores and caves oolitic shoal reservoirs, reservoir spaces include a variety of pores, caves and fractures. Luojiazhai structure is porous reservoir and Gunziping structure is fractured-porous reservoir. All above-mentioned provide the basis for further development.
