脉冲中子氧活化水流测井西区采油厂的应用

随着西区采油厂油田开发的不断深入,调剖的介质也从水发展到聚合物等,由于这些流体介质粘度高,常规的测井方法不能完全适应注入剖面的监测需要,一定程度上影响了油田注采关系的协调。西区采油厂引进的脉冲中子氧活化水流测井技术,是利用高能中子与水中氧元素的活化反应来探测水的流动情况,这一技术不受流体粘度、管柱结构、岩性、空隙结构和大小的影响,能进行磁定位井温、压力、自然伽马等参数的测量。该技术不使用任何放射性示踪剂,因此不会产生沾污、沉淀、污染等问题,是新一代环保型测井新技术。

Application of Pulsed Neutron Oxygen Activation Water Logging in Western Oil Recovery Factory

With the production of Xiqu oil recovery dium water development to polymer from, because these factory development unceasingly thoroughly, the stimulating me- high viscosity fluid medium, conventional logging methods can not adapt to the injection profile monitoring, and impact on the oilfields of injection - production relation coordination. Production of the introduction of the pulsed neutron oxygen activation logging technology was to use water, high energy neutron oxygen and water element to detect the activation reaction of water flow, this technology from fluid viscosity, string structure, lithology, structure and size of the space, can affect on magnetic temperature, pressure, positioning well natu- ral gamma ray and other parameters of the measurement. The technology without any radioactive tracer, would not have contamination, precipitation, and pollution, was a new generation of environmental protection logging new technology.
