PREDICT FAVORABLE DEVELOPMENT BELTS OF QIXIA FORMATION, DAXINGCHANG AREA, SOUTHWESTERN SICHUAN BASIN
【Abstract】 Affected by shoal facies, the crystal dolomite and grain limestone reservoirs are widely developed at Qixia Formation, Daxingchang area. The reservoirs belong to fractured and porous ones. In the study, the geological features of study area were analyzed; the paleogeomophic restoration was carried on based on some characteristic of seismic response, well-logging response; sensitivity attributes were selected to predict a favorable reservoir development belt. Moreover, fracture was predicted, and small fractures and some fracture development areas might be found. At the same time, hydrocarbon detection was implemented by means of post-stack seismic attribute. Finally, the development belt of Qixia Formation could be predicted through the above results and structural achievements.
