珠江口盆地惠州地区A区块碳酸盐岩油气储层预测

PREDICTION OF CARBONATE RESERVOIRS IN BLOCK A OF HUIZHOU AREA IN PEARL RIVER MOUTH BASIN

  • 摘要: 珠江口盆地珠江组碳酸盐岩油藏在近年取得了勘探新突破,如LF15-1油藏的成功评价,极大地鼓舞了区域碳酸盐岩勘探。由于碳酸盐岩储层非均质性强、分布复杂,受古地形、沉积环境、成岩作用叠合影响,储层评价困难。笔者在前人研究的碳酸盐岩地层速度和储层孔隙度呈线性关系成果的基础上,充分挖潜地震资料计算碳酸盐岩地层速度对研究区储层发育区进行宏观分析,结合叠前叠后联合相控反演进行碳酸盐岩储层精细刻画,在研究区评价出3个有利储层发育区,识别出有利储层Ⅰ区是一个规模超过12 km2的岩性圈闭,为区域后续勘探奠定了良好基础。

     

    Abstract: The exploration of carbonate reservoirs of Zhujiang Formation has been breaked through in The Pearl River Mouth Basin. recent years.For example, LF15-1 oil pool had been successful evaluation, encouraging the regional carbonate exploration. However, because of the carbonate heterogeneity, reservoir is very Complex.The carbonate reservoirs is effected by paleotopography, sedimentary environment and diagenesis, so it is very difficult to make the reservoir evaluation. Based on The results of previous studies:a linear relationship of the carbonate strata interval velocity and reservoir porosity, The author made macro reservoir prediction using interval velocity transformed by seismic RMS velocity.At same time, carbonate reservoir has been made fine description, combined with the prestack and poststack joint inversion of facies controlled. In the study area, three favorable reservoir is identified.the best favorable reservoir zone is lithologic trap,which is more than 12 square kilometers. Research production is good foundation for regional exploration in the future.
