摘要

本文在前人工作基础上,通过综合利用地震地层学、储层地质学、测井地质学及石油数学地质的理论和方法,阐述了万全地区沙三段地震地质特征,探讨了三角洲地区的储集层对比法,描述了储集层的沉积分布特征及孔隙度发育特点。通过环境校正、油田测井资料数据标准化,利用多元逐步回归分析、最佳曲面拟合技术,建立了储集层属性参数与测井响应值间的转换关系,描述了目的层储集参数的空间分布特点,建立了典型砂岩体的数学模型。利用模式识别及模糊综合评价技术,对工区储集层进行了分类与评价,预测了有利的储集层储集区。
In this paper,on the basis of previous work,by the use of the theories and methods of seismic stratigrapthy,reservoir geology,logging geology and petroleum mathematical geology,the seismic geological characteristics of BS3 in the Wanquan area are dealed with,the method of correlation of reservoirs in the delta area is discussed,and the depositional and distribution characteristics of the reservoirs and are also described.By means of the environment correction,oilfield logging data normalization and methods of multi-step regression analysis and the best approximation of curved surface,the conversion relationship between the reservoir parameters of ES3 and its logging responsive values in this area has been determined,the spatial distribution of the target reservoir paramters has been described,and the mathematical model of typical sand body has also been constructed.By making use of the technique of pattern recogition and fuzzy synthesizing judgement,pavorable reservoir strata and area has been predicted.
