中文摘要: 塔里木盆地哈拉哈塘地区走滑断裂发育类型多样,平面上表现为明显的分段性,活动期次上具有多期性与继承性发育的特点。基于地震资料,采用多种方法查明了哈拉哈塘A地区断裂平面展布特征,并结合应力性质对哈拉哈塘A区块走滑断裂的发育特征进行研究,明确了走滑断裂对油气差异富集的控制作用。研究发现,研究区共发育3条主干断裂,根据断裂组合样式、地震剖面及古地貌特征将这3条走滑断裂分为张扭、压扭、走滑等12段;深大断裂带控储控藏特征明显,走滑断裂不同应力段控制岩溶储集层发育和油气富集;走滑断裂压扭段及张扭段的构造高部位易形成大型缝洞集合体,是优质储集层发育与油气成藏的优势区域。
Abstract:There are various types of strike-slip faults in Halahatang area, Tarim basin, which show obvious segmentation in the plane and characteristics of multistage and inheritance development during the active period. With the help of innovative geophysical method, the author identified the characteristics of faults spreading in the plane. In addition, combining with the nature of stress we studied the development characteristics of strike-slip faults in Block A of Halahatang oilfield and clarified their control effects on differential enrichment of hydrocarbons. The study shows that there are three main faults in this area which can be divided into 12 segments, such as transtensional, transpressional, strike-slip section. Deep fault plays an important role in the development of reservoirs, and the development of karst reservoir and accumulation of oil and gas are controlled by different stress segments of faults. Large fracture-cavity aggregate is easy to be formed in high tectonic position of transtensional and transpressional section of strike-slip fault which is the advantage area for high quality reservoir and hydrocarbon accumulation.
