The Application of Seismic Facies Recognition Technology in Sedimentary Facies Research of Cambrian at East of Tarim Basin

The exploration and geology research level is lower at East Tarim basin and the studying of carbonate reservoir at deeper basin is also inadequate in special.Dolomite of Cambrian is the prospect area, there has good condition to form high quality stratum which will be got breakthrough on exploration of oil and gas. the study aim at the uplift belt of East Tarim basin (low uplift of Gucheng-uplift of East Tarim basin -uplift of Lop Nur), optimized 267 2D seismic survey line 24670 km in total which cover the whole area with no less than 16 x16km grid density, basic on the fine structure interpretation, make full use of the area for drilling, well logging and core data, combined with peripheral outcrop zone and the predecessors' research result to study the paleogeography and controlling factors of the carbonate stratum of Cambrian in East Tarim basin by means of seismic facies studying system, the result provide important reference for oil and gas exploration in this area.
