Abstract:
The predecessors don’t do research Southern junggar,kara,Ann sea etc.Through the surface and the drilling situation,The kara regional geological features of oil sands has carried on the detailed description,the oil sands reservoir rock type to sandstone and glutenite is given priority to;Reservoir physical characteristics,good porosity is in commonly 15.74%~22.69%,permeability is as high as 277.07 mD;Patterns through research,probes into the oil sands are mainly for elevating the transformation type,kara sand thickness and distribution area is larger,the oil content is higher,generally can amount to 4.4%,Because of the oil sands 1 well drilling success,The large resource potential and exploration value have been confirmed of the tianshan piedmont tectonic belt in the south edge of junggar basin,Oil sands has vigorously promote in basic geological work,to guide the oil sands resource exploration and evaluation next step.
