Abstract:
Zhongguai swell is an important area for petroleum exploration in northwestern margin of Junggar basin, and its Lower Jiamuhe formation is the main target zone. Oil and gas shows occurred in Guai?3, Xinguang?1, Guai?201wells at this formation in southern slope of Zhongguai swell, and also got commercial oil?gas flow up to now. However, the scattering oil?gas yielding points allowed the reservoir to be more complicated. In view of the complexity of Jiamuhe reservoir, many geophysical methods are used to analyze it. It is suggested that the conventional impedance inversion cannot be applied to fine description of such a reservoir, but waveform division and oil?gas containing detection technologies can do it. And the idea of finding“sweet spot”areas in the favorable sedimentary facies well solves the difficulty of lateral heterogeneity in the reservoir, providing theoretical guidance for the next step of exploration and deployment in this area.
