在岩石物理分析的基础上,利用波形相控反演与模拟相结合的方法,并结合拟声波阻抗重构技术及基于坐标旋转的储层参数指示构建技术,对黄骅坳陷沧东凹陷南部中高斜坡区古近系孔二段的致密砂岩储层进行预测。研究结果表明:(1)波阻抗曲线对于砂岩和泥岩的识别效果较差,而自然伽马能以83 API为界限值有效区分砂岩与泥岩,优选的自然电位曲线不仅能以-13 mV为界限值有效区分砂岩和泥岩,对于储层与非储层也具有一定的区分能力。(2)重构后的拟声波阻抗曲线提高了对砂岩和泥岩的识别能力,基于坐标旋转的储层指示曲线以-10为门槛值划分储层与非储层,且储层指示曲线可实现对致密砂岩储层的预测。(3)波形相控反演与模拟相结合的储层预测方法能够提高致密砂岩储层预测的精度,并可降低储层预测的多解性,储层预测符合率达83.3%。
