【摘要】 侵入岩体油气藏是火成岩油气藏的重要类型之一。传统上对侵入岩体各亚相带的研究和判断,主要通过钻井取心来认识。本文以惠民凹陷西部沙三段已钻遇侵入岩体的实钻资料为依据,尝试性地对沙三段侵入岩体各亚相带及热解触变质带的地震、电测响应特征进行研究,总结出一套较为实用的通过岩屑录井、钻时录井手段识别所钻遇的各亚相带和进行侵入岩体顶、底界卡定方法,现场应用效果很好。更多还原

【Abstract】 Irruptive rock body reservoir is one of important volcanic rock reservoirs.Traditionally,various subphase belts for irruptive rock body are studied and analyzed by mainly drilling well and coring.This paper is based on practical drilling data of drilled irruptive rock body in western Sha III segment of Huimin Depression,rock body subfacies in this phrase and seismic,electric logging features in pyrolysis metamorphic belt are analyzed,so as to summarize a set of practical methods,which identify drilled various subfacies and irruptive rock top and bottom boundary by cuttings log and drill time logging.更多还原
