| 摘 要： | 塔里木盆地巴楚凸起奥陶系潜山天然气勘探前景广阔,已发现和田河气田和山1井气藏。该区烃源岩好,储层盖层组合匹配完好,圈闭面积大,是有利的油气勘探区域。通过对和田河气田和山1井气藏特征的综合研究,发现气藏的形成主要受控于烃源岩、断裂、不整合面和岩溶作用,只要4个控制因素相匹配,就可形成大型天然气藏。结合国内外碳酸盐岩气藏的勘探实践,对该区碳酸盐岩气藏的形成和分布规律进行了总结,其规律是：沿古隆起分布,沿断裂带分布,沿不整合面分布,近烃源岩分布。根据潜山气藏的主要控制因素和分布规律,该区应选择志留系和奥陶系尖灭线以南以西的和山1井与玛参1井一线和色力布亚断裂带为主要勘探目标,应对岩溶较为发育的卡拉沙依断裂带进行系统研究。 |

| Abstract: | The Ordovician buried hills in the Bachu rise, Tarim basin, has good gas prospecs. The Hetianhe gas field and well Shan 1 gas accumulation were discovered in this area. The area has good hydrocarbon source rocks, a well-matched association of reservoir and cap rocks and a very large trap so;it is an advantageous area for petroleum exploration. According to an integrated study of the characteristics of the Hetianhe gas field and well Shan 1 gas accumulation, the authors suggest that the formation of gas accumulations was principally controlled by hydrocarbon source rocks, faults, unconformity and karstification. So long as the four controlling factors can match well, large gas accumulations can be formed. Based on this study, combined with exploration practice in carbonate gas accumulations both at home and abroad, the distribution characteristics of carbonate gas accumulations are summarized as follows: they are distributed along paleo-uplifts, along faults, along unconformities and near hydrocarbon source rocks. According to the principal controlling factors and distributing characteristics of buried hill gas accumulations, in the study area the zone south and west of the pinch-out line of the Silurian and Ordovician, the line of wells Shan 1 and Macan 1 and the Selibuya fault zone should be chosen as the chief exploration targets. In addition, a systematic study should be carried out on the Kalashayi fault zone where karst is well developed. |
