| 摘 要： | 近年来取得的油气勘探突破多与古构造活动区密切相关，如渤海湾盆地大港油田千米桥潜山凝析气藏、鄂尔多斯盆地靖边气田、塔里木盆地和田河气田及塔河油田的发现等。多年来的勘探实践证明，适时的古构造隆起对油气运移、聚集和成藏起着十分关键的作用。研究认为构造活动还直接控制着古风化壳岩溶裂缝—洞穴型、裂缝型等多种类型储层或储集体的发育。提出了岩石构造相的概念及分类体系；指出岩石构造相是岩石固结成岩后在不同时期所受构造作用的物质体现，可以按照岩石地层单元、构造运动期次及构造运动方式对其进行分类。分别以冀中坳陷任丘雾迷山组古潜山油藏及四川盆地赤水地区须家河组气藏为例，分析了抬升岩溶构造相及节理构造相储层的特征；认为前者多见于碳酸盐岩，各种溶蚀孔、洞、缝为储集空间，而后者见于不同岩类，构造裂缝及其伴生孔隙为储集空间，它们的物性特征都比较复杂。建议加强储层岩石构造相的研究，开展相关识别技术的开发。

| Abstract: | In these years, new discovery of petroleum exploration has often been in connection with the palaeo tectonics active regions, such as the finding of Qianmiqiao condensate pool at Dagang Oilfield in Bohaiwan Basin, the exploration of Jingbian Gas Field in Ordos Basin and the finding of Hetianhe Gas Field & Tahe Oilfield in Tarim Basin, etc. According to years of exploration experiences, good palaeo uplift had bad vital function for the migration, accumulation and reservoiring of oil and gas. Our studies showed that tectonic movements controlled the development of many a types of reservoir: the karsting fracture caved reservoir from prior weathered crusts and fractured reservoir. We appointed the concept and classing system; pointed out that the petrotectonic facies are material showings of tectonic movements in rocks solidified, and fingered they can classified by rock stratigraphic unit, tectonic movement stage and style. Beyond the analysis on the Mumishan Formation oil pool from buried carbonate hill of Renqiu Oilfield in Bohaiwan Basin and the Xujiahe gas pool of Chishui gas field in Sichuan Baisn, the reservoir characters was discussed for uplift karsted petrotectonic facies and joint petrotectonic facies. The forward facies is found mostly in carbonate stones, whose reservoir space are all kinds of pore, cave and fracture lined to karst; the following facies can be found in different rocks, whose reservoir space are tectoclase and correlated pores; reservoir physical properties of the two facies are both relative complex. We advice to strengthen the research of reservoir petrotectonic facies; we meanwhile hope to carry out the development of associated recognition technique for petrotectonic facies of reservoirs. |
