HDC集流法产液剖面测井仪的研制

产液剖面测井能够提供井下各相流体的分层产量、持水率等参数。针对油田开发后期抽油井过环空产液剖面测井中存在着流量与持水率测量精度下降的问题，提出了集流法产液剖面测井技术。HDC集流法产液剖面测井仪采用涡轮流量计和持水率计一体化设计，金属伞封隔流道，实现流量与持水率2个参数的同时测量。集流测井提高了井筒中流体流速，减小了各相流体间的滑脱速度，改善了流体混合均匀程度，有效地提高了生产测井资料的质量和解释精度。

Development of HDC packer-flow production profile logging tool

The production and hold-up of each zone in borehole can be provided by production profile logging. For annulus production profile logging in pump well, as the accuracy of flow capacity and water hold-up descend in later stage of oil field developing, the packer-flow production profile logging technique is put froward. The packer-flowmeter and the water hold-up probe are designed with an organic whole, metal umbrella to pack flow channel. The tool can measure flow capacity and water hold-up at one time. The packer-flow technique improves the velocity of fluid in bore hole, reduces the slip velocity between phrases, changes the mixture degrees of fluid, thus enhancing the quality of measurement and the accuracy of interpretation.
