摘　　要：注钆中子寿命测井能否进行压裂缝检测,国内外很少见到这方面的报道和应用。针对该问题,进行了注钆中子寿命检测压裂缝的试验。从井眼影响、径向探测深度及有效裂缝内钆浓度方面进行了一系列试验,获得了大量的试验数据和认识。Whether injection of gadolinium neutron lifetime logging can be used to detect the induced fractures is rarely reported.A series of tests are done to study the feasibility from borehole effect,radial depth and the Gd concentration in the effective fractures.A large amount of test data and understanding are obtained from the tests.

关 键 词：注钆中子寿命测井 井眼影响 径向探测深度 有效裂缝
