| 摘 要： | 塔中地区是塔里木盆地的重点勘探区域,奥陶系鹰山组蕴藏了丰富的油气资源。鹰山组发育大套台地相碳酸盐岩,以高能相的台内滩沉积为主。鹰山组埋藏较深,但岩溶储层呈大面积厚层状分布。早奥陶世塔中I号断裂使得塔中隆起隆升并遭受强烈剥蚀形成下奥陶统鹰山组顶部风化壳,以孔洞型和裂缝-孔洞型储层为主。通过古地貌恢复、地震属性分析和地震测井联合波阻抗反演技术和方法识别溶洞发育带和断层裂缝发育带,确定出有利储层的分布范围。研究认为,岩性岩相是岩溶型储层发育的重要基础,层间岩溶控制了储层的成层性和横向展布规模,断裂和裂缝网络是岩溶水的主要渗滤通道,埋藏岩溶形成大量有效的缝洞空间,极大地提高了储集性能。研究发现,优质储层主要分布在鹰山组顶面以下120m地层厚度范围内,横向有一定连通性,在断层、构造裂缝和溶蚀作用下形成统一的储集体,呈准层状展布。

| Abstract: | Tazhong area in the Tarim Basin is the focus of the exploration area, the Ordovician Yingshan Formation encompassed the rich oil and gas resources. Yingshan developed a large set of platform facies carbonate rocks, with high-energy deposition relative to the main of intra-platform shoal. Yingshan buried deep, but a large area of karst reservoir was thick layered distribution. Early Ordovician fracture TaZhong I, making the TaZhong uplift uplifted and subjected to intense erosion to form at the top of the Lower Ordovician weathering crust Yingshan to vuggy and fracture - vuggy type reservoirs. Through the ancient landscape restoration, seismic attribute analysis and seismic acoustic impedance inversion joint logging techniques and methods of identifying cave development zone and the fault fracture zone, determine the scope of the distribution of favorable reservoirs. Studies suggest that lithology facies development of karst reservoir is an important basis for interlayer karst control of the reservoir into a horizontal layer of the Spread and the scale of fracture and fracture network is the main karst water percolation channel, buried karst formation the number of available fractured-vuggy space, which greatly improved reservoir properties. The study found that high-quality reservoirs are mainly distributed in the following top 120m Yingshan stratigraphic thickness within a certain horizontal connectivity, and in faults, structural fractures and corrosion under the action of the formation of a unified reservoir, was quasi-layered Spread. |
