摘要
涠10－3N古潜山是由断层切割倾向北西的单斜层构成的翘倾断块，地貌特征呈南陡北缓的单面山。本文通过倾角测井资料证明。古潜山岩层倾向为北北西向，倾角10°-20°。经各种测井及地质资料的综合分析，认为：该潜山缝洞十分发育，裂缝类型为垂裂缝和网状裂缝。1、2井区主裂缝发育方向分别为北东东向和北西向，反映两个井区的最大地应力的方向不同。储集空间为溶洞、构造裂缝和粒间孔隙三者的复合型。
Wei 10-3N buried hill is a tilting fault block consisting of faulted monocline striking in north-west, with geomorphic features of cuesta characterised in steep south and flat north.This paper proved the NNW strike of buried hill formations with a dip angle of 10°—20° from the dipmeter data.From composite anal- ysis of various logging and geological data,it has been noted that the buried hill is abundant in fractures and pores.Fracture types are vertical and net-shaped fractures.In Well 1,2 blocks,main fractures are in the directions of NEE and NW,respectively,which indicates different directions of maximum geological stress in the two well blocks.Pore space is compositely consisted of dissolved pores,structural fractures and interstitial pores.
