摘　　要：本文论述了我国含油气盆地中作为扭断裂典型剖面特征的花状构造的鉴别标志、力学机制及其石油地质意义.作者认为我国中、西部地区发育正花状构造,而东部诸盆地中则以负花状构造为主.它们分别代表中、新生代盆地中压扭和张扭两种不同的构造背景.这种扭动构造背景控制了盆地的结构、沉积相带的发育、油气圈闭的类型和空间分布,直接影响着油气远景评价和预测.This paper is an exposition on the discrimination markers and the mechanism of flower structures as sectional characteristics of typical wrench fau-lts around oil and gas bearing basins in China, and the structural significance in petroleum geology. The authors believe that positive flower structures develop in the central and the western part of the country, while negative ones dominate the east. Respectively, they represent transpression and transtenssion two distinctive structural backgrounds in the Mesozoic and Cenozoic basins, which control the general structure of the basin, the development of the sedimentary facies zones, and the types of oil and gas traps and their spacial distribution, which in turn, directly influences the evaluation and prediction of oil and gas prospects.
