Progressive Appraisal of Xing-9 Conglomerate Reservoir in Langgu Sag

Abstract

Abstract: Xing-9 conglomerate reservoir, a lithologic condensate reservoir, lies in the central and northern of downthrow side of Daxing fault west of Langgu sag. Five wells have been drilled in the conglomerate terrain, two of which have stable commercial oil and gas flow. Through the origin analysis of conglomerate, study on lithologic oil and gas accumulation conditions, target processing of high-fidelity seismic data, fine horizon calibration, and multiple seismic attribute analysis in the past years, the oil and gas reservoir accumulation patterns of "slip-phase conglomerate rich in oil and gas as a whole" and "gas reservoir below gas reservoir" are established. Through adopting the strategy of "evaluating on the whole, implementing step by step, combining rolling evaluation and capacity construction", the rolling evaluation has progressed a lot, and the conglomerate reserves have exceeded 10 billion cubic meters.

Key words: conglomerate gas reservoir, target processing, reservoir prediction, reservoir accumulation pattern, reserve scale, Langgu sag
