石灰岩是地表出露最为广泛的碳酸岩地层,约占整个陆地总面积的15％,由于受地质构造岩性等因素的影响,地下水(基岩裂隙水、岩溶裂隙水)的分布很不均匀,从而为定并、洗井工作增加了难度。为更准确地掌握盐酸与灰岩的化学反应变化情况,我们在鲁中南石灰岩山区选择了中奥陶石灰岩、下奥陶白云质灰岩、风山组灰岩、张夏组白灰岩鲕状灰岩及馒头组灰岩等6种岩石,在室内与盐酸进行化
Limestone is the most widely exposed carbonate layer on the earth’s surface, accounting for about 15% of the total land area. Due to the influence of geologic structural lithology and other factors, the distribution of groundwater (bedrock fissure water and karst fissure water) is not uniform, As a result, flushing wells have become more difficult. In order to know more accurately the change of chemical reaction between hydrochloric acid and limestone, we chose the Middle Ordovician limestone, the Lower Ordovician dolomitic limestone, the Fengshan Formation limestone, the Zhangxia Formation limestone oolitic ash Rock and steamed breadstone limestone six kinds of rock, indoors and hydrochloric acid into
