古地貌恢复是研究碳酸盐岩古岩溶发育情况的一项重要的基础工作,古地貌恢复的方法有很多,层拉平法是在物探资料基础上,以层序地层学的观点为基础发展起来的,利用层拉平法恢复和描述出的古地貌形态非常直观,利于研究。本文以T油田X区奥陶系油藏为例,利用层拉平法恢复和描述了T油田X区奥陶系在石炭系开始沉积之前的形态特征。
The restoration of palaeogeomorphology is an important basic work to study the development of paleokarstification of carbonate rocks. There are many methods for the restoration of ancient landforms. The leveling method is based on the geophysical data and based on the view of sequence stratigraphy , The paleogeomorphology recovered and described by the layer leveling method is very intuitive and conducive to research. In this paper, taking the Ordovician reservoir in X zone of T Oilfield as an example, the stratiform leveling method is used to recover and describe the morphological characteristics of the Ordovician in X zone of T Oilfield before the sedimentary start of the Carboniferous.
