The Odd Akekule East Sandstone Reservoir Prediction Of Tarim Basin In Xinjiang

In this paper, cores, logs, seismic data, the establishment of stratigraphic framework and sedimentary facies analysis, the use of seismic inversion and seismic attribute extraction technology, describes the thickness of the East River and distribution of sandstone. After all the hard work of the researchers, the main body of the project has been completed research work. Favorable area for the study area to achieve the following key understanding:1,The only self-study area, well the odd one in the depth of 5605.0 ~ 5621.0m wells drilled on the Devonian System Donghetang, depending on the thickness of only 16.0m, 2.0m thick at the top of the group than the mudstone, the The development of a layer of sand, only a row of thick 14.0m. Caohu areas due to lack of well data and detailed comparison of the cores, so the odd sequence of division 1 well vested and reservoir evaluation of physical properties must be combined with regional comparative study.2 Department of Sandstone target layer thinner sedimentary sequences, it is difficult to accurately seismic profiles in the domain partition and the system calibration is required by seismic inversion and seismic attribute extraction and other geophysical methods Sandstone reservoir distribution prediction Law and sedimentary facies.3, No. 2 on the small dry lake constructed to the purpose of the East River sandstone layer YQ8 drilling wells drilling results in detail. If the wells in the target layer is a breakthrough on the small dry lake to be constructed (YQ8) for special treatment, using a variety of seismic attribute technology, describes the Sandstone thickness, distribution and reservoir characteristics.
