宣威热水-沾益德泽地区早寒武世筇竹寺期沉积了一套以砂、粉砂和泥质沉积为主的黑色页岩。该黑色页岩成藏了一个良好的页岩气藏。区内黑色页岩有机碳（TOC）的平均值大于2.0%、有机质类型为Ⅲ型、热成熟度3.5%、脆性矿物含量占52.2%~92.8%，平均73.02%、隙度为0.8850%~20.2926%，平均6.0554%、厚度400~200m、埋深1500~3500m、含气量3.70cm3/g~3.81cm3/g，平均3.755cm3/g。区内的盖层、储层和水文条件都有利于页岩气藏的保存。并且区内发育了多条逆断层，断裂构造使页岩形成了很多裂隙构造，对页岩气的成藏起到了促进作用。%There were a lot of black shales in Reshui, Xuanwei-Deze, Zhanyi area of Yunnan province. These black shales include deposition of most of sand, silt and clay. Meanwhile, these black shales bring a high quality of disposition of shale gas. In this area, the average of organic Carbon lied in black shales is greater than 2.0% and the type of organic matter is Ⅲ and the thermal maturity is 3.5%. the brittle mineral content accounts 52.2%~92.8%, its average is 73.02%. the gap is 0.8850%~20.2926%, its average is 6.0554%. The thickness of black shales is 400~200m, the depth is 1500~3500m, gas content is 3.70cm3/g ~3.81cm3/g, its average is 3.755cm3/g. The caprock, reservoir and hydrological conditions are favorable for the preservation of shale gas reservoirs. Many faults are developed in the area, and the fracture structure makes the shale a lot of fracture structures. These can promote the shale gas reservation.
