Well Logging Interpretation Of Liuquan Oilfield

Depression Langgu is an important oil production zone of HuaBei oilfield. And it is awell developed gas reservoir. Starting with the interpretation difficulties of evaluatingreservoir, this paper established the interpretation models and methods of gas and oil byanalyzing the logging response characteristics systematically.geology and reservoir characteristics is first analyzed of the study area in this paper.Then the four properties of the tectonic belt in Liuquan oilfield are studied. based onconventional logging data, nuclear magnetic resonance logging data and array inductionlogging data, lots of data comparison and analysis are proceed on the premise ofstandardization, and finally edit the special curve features. For developed gas reservoir,methods of identifying gas reservoir were established by analyzing logging data.Interpretation model of identifying reservoir petrophysical property parameter wasestablished by analyzing conventional logging data and coring data. According to arrangingmaterial and analyzing4m lateral resistivity curve, low resistivity reservoir can be identified.And the interpretation standard of water-oil reservoir is improved.In this paper, the characteristics of reservoir type and pore structure are analyzedthrough core data and logging data, combined with the testing data. ways of strengtheninglithology identification are studied through the application of core datas. Based on theanalysis in lithology, the interpretation model of the parameters is improved. methods ofevaluating various types of complex lithology reservoir are established using conventionallogging data. The purposes to improve interpretation accuracy of reservoir parameters andto improve the rate of hydrocarbon layer identification are achieved.
