| 摘 要： | 钆中子寿命测井是在硼中子寿命测井改进中发展起来的一种油藏动态监测新技术,采用"测-渗-测"方式,通过向地层渗入钆溶液改变井筒附近地层水的俘获截面获取地层剩余油信息.通过试验研究.探讨了钆中子寿命测井在低孔低渗油藏的适应性,提出了相应的测井工艺,建立了相应的确定产层剩余油饱和度的解释模型.

| Abstract: | Gadolinium neutron lifetime logging (GNLL) is a new technique used for detecting reservoir performance, which is developed by the improvement of boron neutron logging. The technique of logging-infiltrate-logging is used to capture the data of remaining oil by changing the captured cross-section near the wellbore through infiltrating gadolinium solution into the formation. The adaptability of GNLL in low porosity and low permeability reservoirs is discussed in experiment and corresponding logging process is proposed, related model for determining the remaining oil saturation in the pay zone is established. |
