摘要
西北巴拉望盆地油气资源主要集中在第三系生物礁储层中,该区生物礁形态多样,类型复杂,预测难度大。针对该区礁灰岩的储层特点,综合利用地震、地质、测井和钻井等资料,以地震沉积学为指导,综合运用地震属性和波阻抗反演划分有利储集相带,交叉应用AVO技术和烃类检测等技术研究含油气性。初步探索出1套适合于该区生物礁识别和预测的方法,摸清了礁灰岩的分布规律和储层特征,预测了生物礁的平面分布范围,划分了有利勘探相带,为该区的深入研究打下了基础。
Petroleum resources of northwest Palawan Basin are mainly held in Tertiary reef reservoirs,which vary in shapes and types and are difficult to predict.Favorable reservoir facies are divided based on the characteristics of reef limestone reservoirs by using seismic,geological,logging and drilling data as well as seismic attributes and wave impedance inversion under the guide of seismic sedimentology;and the oil-bearing property is studies with the help of AVO and hydrocarbon detection techniques.This research has worked out an applicable method for identification and prediction of organic reefs in this area,ascertained the distribution rule and characteristics of the reef limestone reservoirs,predicted the distribution range of reefs,and divided favorable facies of exploration,thus laid a foundation for in-depth study in this area.
