国内产液剖面测井技术面临的挑战与取得的新进展

摘要

With regard to the challenges and urgent problems in the producing profile well logging technology used in the domestic onshore oilfield, the logging technologies were studied respectively in the high water-cut well, the low yield liquid well , the horizontal well , and the well under the condition of oil-gas-water three-phase flow.Meanwhile, the following instruments were also developed: the high resolution water cut meter and the electromagnetic flow meter applied in the high water cut well , the production profile logging tool based on separation method applied in low production and low permeable reservoirs , the optical fiber gas hold-up tool in the oil-gas-water three-phase flow oil well, and the same layer injection-production storage water hold-up meter in special string .The above instruments were tested by means of large multiphase flow devices , and they were improved through optimization design .The field tests have also been done , which based the foundation to solve the problems in the production profile well logging .%针对国内陆上油田产液剖面测井技术面临的挑战和亟待解决的问题，重点开展了高含水井、低产液井、水平井及油气水三相流条件下测井技术研究，开发出了应用于高含水油井的高分辨率含水率计和油水两相流电磁流量计、应用于低产低渗油田的分离式产液剖面测井仪、用于三相流测井的光纤探针持气率计、应用于水平井的水平井测井新技术及针对特殊管柱工艺的同层注采储存式含水率计。借助大型多相流装置进行实验研究，对仪器结构进行了优化设计，并开展了现场试验，为解决多相流产液剖面测井难题奠定了方法基础。
