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。
The potential exploration potential of Ordovician buried hills in Bachu uplift in the Tarim Basin has revealed that the Hetianhe gas field and the Shan 1 well gas reservoir have been discovered. The source rocks in the area are good, and the matching of the reservoir caprock is complete and the trap area is large, which is a favorable oil and gas exploration area. Through the comprehensive study on the characteristics of Hetianhe gas field and Shan 1 well, it is found that the formation of gas reservoirs is mainly controlled by source rocks, faults, unconformities and karstification. As long as the four control factors are matched, the formation of large Natural gas reservoir. According to the exploration practice of carbonate reservoirs at home and abroad, the formation and distribution of carbonate gas reservoirs in this area are summarized. The regularities are along the paleohigh, along the fault and along the unconformity , Nearly source rock distribution. According to the main controlling factors and distribution laws of buried hill gas reservoirs, the first line of He-Shan-1 well and the first line of Ma-Shen-1 well and the Seri-Liya Fault Belt should be selected as the major ones in the Silurian and Ordovician Fencing Line Exploration targets should be systematically studied on the karataisi fault zone with more developed karst.
