摘要:
 为实现水平井段沿程产出剖面及油水两相持率的连续监测，从电学、声学、光学等角度开展研究，形成了水平井产出剖面光纤监测方法和示踪剂监测方法。这两种方法均将传感器或示踪剂预置在完井管柱上，可实现水平井产出的连续监测。光纤监测方法在X23A20H1井首次实现了每米水平井段油水产出剖面高精度的实时和全油井生命周期的连续监测；示踪剂监测方法首次在L11C7H3井 的5个封隔水平段油水产出剖面进行了2~3年的连续监测，效果良好。该方法为水平井段水淹分析、剩余油分布研究和水平井出水治理措施的制定提供了直接而又丰富的资料，同时也为不具备传统送入式测试法作业条件的水平井各相产出剖面监测成为可能。
Abstract:
 o realize the continuous monitoring of production profile and oilwater twophase holdup along the horizontal well section, the optical fiber monitoring method and tracer monitoring method of production profile of horizontal wells were developed after researches from the electric, acoustic and optical perspectives. In both methods, sensors or tracers are preset on the completion string, which can realize the continuous monitoring of horizontal well production. The optical fiber monitoring method realized a highprecision, realtime and lifecycle continuous monitoring of oil/water production profile per meter of horizontal well section in Well X23A20H1 for the first time. The tracer monitoring method was successfully used, for the first time, to continuously monitor the oil/water production profiles of five isolated horizontal sections of Well L11C7H3 for 23 years. These methods provide direct and abundant data for the analysis of water flooding in horizontal well section, the study of remaining oil distribution and the solution to water production in horizontal wells, and also make it possible to monitor the production profile of each phase of horizontal well without the conditions for tests based on traditional conveying method.
