中文摘要：
子洲地区二叠系山西组山23高阻抗石英砂岩形成于三角洲前缘沉积环境,埋藏深度浅,储集条件好,单井产量高.但是由于砂体很薄,且受邻近上部煤层和下部太原组灰岩及本溪组煤层的低频强反射干扰,薄砂体预测存在很大困难.本文将广义S变换薄层识别技术用于含煤地层薄砂体的刻画,提出了一套薄层识别流程,并用模型和实际资料进行了检验.该技术在子洲地区成功地刻画了薄砂体的分布及形态,为井位部署提供了很好的依据.
英文摘要：
The third sub-member high impedance quartz standstone of the second member of Shanxi formation, the Permian System in Zizhou, deposited shallowly in delta front is good reservoir bed with high individual well producing rate. But the thickness of the quartz standstone is very thin,and its reflect is suffered by the influence of strong reflections generated by near upside coal bed, the limestone in Taiyuan formation and coal bed in Benxi formation of under stratum. Thus it is very difficult in predicting the thin sand bed. In this paper,we used general S transform with a set of flow to identify thin sand layer in Coal-bearing Strata in Zizhou successfully by test of Model and actual data. We have depicted distribution and morphology of thin sand bodies successfully in Zizhou region by this technology, as well providing a good basis for the drilling deployments.
