Research And Application Of OFA-Ⅱ Quantitative Fluorescence Logging Technology

Quantitative fluorescence logging technology is a special logging technology, its principle is to use the oil contained in the aromatic components which can be inspired and fire the fluorescence in the ultraviolet irradiation, detecting the stratum to contain oil or not and oiliness quantity.The quantitative fluorescence able to make the drilling core, cuttings reservoirs fluorescence intensity quantitative analysis, including the naked eye not to recognize the condensate - light oil, and give for fluorescence spectrum of oil and rock samples and compared concentration levels.According quantitative fluorescence techniques make to quantitatively evaluate Oil Gas and Water for the five-star Jilin Oilfield, Chaluhe light condensate oil and gas producing areas, Yingtai, Sifangtuozi light - fair oil area, Daqingzijing fair oil area, Taobao thick oil area and Sifangtuozi heavy oil area, District of numerical chart can be combined into a stable numerical chart. The application need to integrate spectrum shape changes, eliminating the light, condensate oil fields that the naked eye can not find to show limitations, Quantitative evaluation of spectra of information has greatly enhanced the accuracy of interpretation of logging, and help heavy oil logging to show the high evaluation difficulties. Therefore, the chart combines the plate to enhance the identification accuracy of oil, gas and water, the advantages of quantitative evaluation obviously replace the qualitative series of logging.By distinguishing and researching on the crude oil property's spectrum, We can timely adjust the resolutions of oil and gas exploration of the various exploration area; By researching the spectrum characteristics of the heavy oil area determine the flow of its oil; through researching the availability of the mud additives monitor the changes of local mud capability, and optimize the interpretation of parameters to establish the appropriate interpretation chart in order to complete the ration exploration and evaluation of oil , gas and water layer about the various area of Jilin, and achieve to guide test oil and the exploration deployment in the end, quickly discover the reservoir of oil and gas to protect not leak of condensate - light Oil and gas oil in order to achieve to increase storage capacity.
