研究措勤盆地的烃源岩、储集层、盖层和圈闭的特征 ,剖析各油气系统的发展演化历史 ,对该盆地的油气远景进行预测 .本区下白垩统川巴组的泥质岩 ,多巴组和郎山组的碳酸盐岩是有效烃源岩 ;川巴组的砂岩 ,多巴组的砂岩和碳酸盐岩以及郎山组的碳酸盐岩是主要的储集层 ;川巴组的泥质岩为局部盖层 ,多巴组和郎山组的碳酸盐岩是区域盖层 .燕山晚期运动为本区的油气聚集提供了有效的圈闭 .本区共划分了 7个油气系统 .根据盆地模拟结果综合分析表明 :措勤盆地最有利的油气区是洞错 -阿苏地区 ,该区的 K1ch- K1ch(!)油气系统是最有利的系统 ;其次是马窖 -门当日阿次地区 ,该区以 K1ch- K1ch(?)油气系统最有利 ;油气远景最差的地区是色卡错—麻米错地区
Studying the characteristics of source rocks, reservoirs, cap rocks and traps in the Coqen Basin, analyzing the evolution history of each petroleum system and predicting the oil and gas vistas of the basin, the mud quality of the Lower Cretaceous Chuanba Formation Carbonates in the rocks, the Dopa Group and the Langshan Formation are effective source rocks; the Chuanba Formation sandstone and the Dolba Formation sandstone and carbonate rock and the Langshan Formation carbonate rock are the major reservoirs ; The mudstone in Chuanba Formation is a partial caprock and the Carbonate rocks in the Dooba Formation and Langshan Formation are regional cap rocks.The late Yanshanian movement provides an effective trap for hydrocarbon accumulation in this area According to the comprehensive analysis of the basin simulation results, it is shown that the most favorable oil and gas zone in the Coqen Basin is the Caverns-Aso area, and the K1ch-K1ch (!) Oil and gas system in this area is the most favorable system; - On the same day Amen, the K1ch-K1ch (?) Oil and gas system is the most favorable in this area; the area with the poorest oil and gas prospects is the Xikake-Mami fault region
