油气储层预测技术在琼东南盆地BD13区的应用
|
摘要
琼东南盆地BD 13区中新统三亚组一段地震异常体具有异常范围比构造范围大的特点,且具备良好的油气成藏地质条件,可能属于构造背景之下的岩性圈闭成藏。为了确定该地震异常体的含气规模,利用拟声波地震反演和频谱成像技术联合预测了该套储层,初步搞清了砂体厚度及平面展布特征,在此基础上,利用AVO、AVD、DR及衰减梯度等烃类检测技术进行了储层检测,并应用衰减梯度多信息融合技术预测了砂体含气规模,结果表明,BD 13区三亚组地震异常体含气规模较大,应具有良好的勘探前景。
In BD 13 area,Qiongdongnan basin,South China Sea,Seismic anomaly body of Sanya formation I Section with wider abnormal range than structure size,which may be a gas-bearing lithologic trap formed under a structural background,has good conditions for hydrocarbon accumulation.To determine the potential gas resource,seismic inversion on pseudo-sonic curve combined with spectrum imaging techniques were used to preliminarily predict reservoir thickness and lateral distribution;on the basis of above work,AVO,AVD,DR,decay gradient were carried out to conduct hydrocarbon identification on reservoir,and multi-information syneretizing technology of decay gradient was used to quantify gas resource scale.It shows the seismic anomaly sandbody of sanya formation in BD 13 area has large gas resource potential and good exploration prospect.
