摘要
补偿中子测井,是在中子测井的基础上进行图版校正,克服井眼不规则变化影响的一种中子测井方法。它同时记录长短源距探头的计数值,可在裸眼井或套管井中测量地层孔隙度。其中,Baker Hughes公司的补偿中子测井仪(2446XA)在各油田得到广泛应用,但在测井作业中,也时常出现各种放射源事故,造成人员过量照射,给个人及公司及带来巨大损失。本文就补偿中子仪器及所用放射源(Am-241/Be)展开研究,分析其设计结构及作业中可能遇到的问题,提供了一些解决办法,提高了作业的安全性和时效性。
The compensated neutron logging is a method which based on the neutron logging,can overcome 'affected by the irregular change of the borehole.And records the counts from two different probes, calculated the porosity of the formation in the open hale or casing well.The Baker Hughes Compensation Neutron Logging tool (2446XA)is widely used in oil-fields,But during logging,them are also frequent sourees of radiation accidents,causing people to nvershoot,giving individuals and companies a huge loss.This paper will research compensated neutron logging tool and source (Am-241/Be),analysis the design structural and possible problems during operation,provides a series of solutions,improve the security and efficiency of the logging job.
