兰聊断层是东濮箕状断陷的东边界，紧邻主要生烃洼陷带。多年来人们将其横向分为上下两盘：下降盘发育着下第三系构造和砂体；上升盘存在古潜山和古河道。地质家们一致认为兰聊断裂带石油地质条件优越。长期以来针对不同目标进行了广泛钻探，除早期发现白庙下第三系油气田外，仅有一口井获工业油流，勘探效果不佳。本文对其原因进行了客观的分析，并根据叠前深度偏移处理的三维地震及钻井资料，提出了兰聊断层“横向三分”的新概念，即上升盘、下降盘和夹于其间的复杂断阶带。指出复杂断阶带最为有利，同时提出了今后应开展的工作。
The Lan-Lia fault is the eastern boundary of the East Puji-zang faulted depression, which is adjacent to the major hydrocarbon-producing subsag belt. Over the years, people have divided them horizontally into two parts: the descending plate develops the Lower Tertiary structure and the sand body, and there are ancient buried hill and ancient river in the rising plate. Geologists agree that the Lan-Liaocheng fault zone has superior petroleum geological conditions. For a long time, different targets have been extensively drilled. Except for the discovery of the Tertiary Oil and Gas Field in the Lower Reaches of Baimiao, only one well received industrial oil flow and the exploration result was not good. Based on the 3D seismic data and drilling data processed by prestack depth migration, this paper presents a new concept of the Lanzhou fault “horizontal third”, namely the rising disk, the descending disk and the In the meantime the complex broken order belt. Pointed out that the complex fault-step belt is the most favorable, at the same time put forward the work to be carried out in the future.
