The Formation Evaluation Tool (FET) introduced in the paper represents a new generation of formation evaluation systems developed and manufactured by China Oilfield Services Limited (COSL), CNOOC, using a FET technology transfer from Crocker Research, Australia. The system has been applied successfully in the Bohai Sea and South China Sea. For instance, a multilayered oil and water system has been confirmed with the aid of accurate formation pressure tests, even in very thin beds and edge water reservoirs, overcoming the difficulty of determining this kind of oil-water and gas-water contacts. Moreover, the FET pumping and real-time fluid monitoring function allows acquiring a true sample of formation fluid unpolluted by drilling mud which plays an important role in determining the fluid properties of the target stratum and analyzing the fluid component. The principles and purpose of the Formation Evaluation Tool (FET) will be briefly introduced and successful examples of the application of the technology will be described in detail in this paper. 相似文献

地层测试评价仪(FET)及其在中国海域的应用 总被引:3,自引:0,他引:3
地层测试评价仪(Formation Evaluation Tool)是中海油田服务股份有限公司引进澳大利亚 CROCKER公司技术而自行开发、制造的新一代地层测试评价系统。该仪器已经在中国近海渤海、南海等海域取得了成功应用,其精确地层压力测试能帮助判断多套油水系统,尤其在一些薄层和边水油藏也取得了可靠的测压资料,很好的解决了油水、气水界面确定问题;此外在目的层取样时所具有的污染流体抽排和地层流体特性实时检测功能保证获取不受泥浆污染的真实地层流体样品,对确定流体性质和分析流体成分起到了重要作用。本文主要介绍地层测试评价仪(FET)的原理和用途,以及在中国海域的成功应用实例。 相似文献

A portable salinity meter with field effect transistors for the continuous recording of salinity of rainwater is described. The variations in salinity are converted into current variations by using a D.C. differential amplifier and is recorded on an Esterline Angus Recorder. The Meter enables us to measure rainfall intensity as well as salinity simultaneously. The chief advantages of the present instrument are that it is portable and has a range of measurement from 1×10–4 to 1×10–1 ppm on a linear scale. 相似文献
