Let That Jordan Oil And Gas Fields Of Complex Carbonate Flooded Logging Evaluation Method

The Zhalaroer oil field located in Kazakstan belongs to the block carbonate rock which formed in shallow sea. It is proved by production practice and investigation the compose of the oil well and the production of crude oil that the oil field has reached at high water-cut stage. It is important and intractably to ravel the distribution of the oil and water and make clear the district of the remaining oil underground. The thesis combines the typical characters of the carbonate reservoir, set up a series of synthetical water flooded layer logging appraise methods, which can accurately reflect the changes of reservoir parameter while flooding. the methods can meet the production requires in the oil field and follow the oil exploitative trend, so it is has practical meaning.According the particularity of the carbonate reservoir and the complexity of the parametric changes while flooding, through investigation the Zhalaroer oil field, the thesis aim to set up a series of water flooded layer appraise methods for carbonate reservoir. The thesis divide three parts: first, introduction the theoretical basis of the complex water flooded carbonate reservoir with logging, which include the third and forth chapter. The text get a start in the petrophysical property of the carbonate rock, and introduce the basic characters of the carbonate rock from the logging aspects, and analyze the connection between the logging information and the geological specificities of the fracture-type reservoir, expatiate the ways to evaluate the fractures and vugs with logging material. Last, the this part introduce the wavelet analysis methods. Second, combining the practice data in the oil field, the second part of the text study the parametric changes while flooding, which include lithology parameters properties of matters fluid parameters formation parameters and physical geography parameters. Third, this part integrally study the water flooded layer logging appraise methods for the carbonate reservoir in the Zhalaroer oil field, which include sixth and seventh chapter. According to the practice of the Zhalaroer oil field, this part mainly depend on the log information and combine the geology and exploit material to investigate the water flooded layer logging appraise methods, which include plate ways, electrical property methods, and so on. Then the part also set up a water flooded layer logging quantitative assessment method, which combine the wavelet analysis method and fit the complex carbonate layer. Through computing the water flooded layer parameters and establishing the waterflooding standard, the method can accurately evaluate the waterflooding situation with the numerical simulation data in the Zhalaroer oil field.The Zhalaroer oil field belongs to the fractured-vug type carbonate reservoir, about which the investigation is very few at home and abroad, and the study in this thesis is strictly based on the core analysis in doors and production practice in the field, so, the water flooded layer...
