摘要
井矿岩地层是以盐岩、石膏、硬石膏、芒硝为主,同时含有碳酸盐岩、砂岩和泥岩等岩性的地层,其中碳酸盐岩和泥岩可成为盐岩层较好的盖层和隔层,这些盐岩地层地球物性特征较好,盐层与围岩物性差异大,盐层的主要有效参数曲线特征明显。应用地球物理测井方法,能有效的解决钻孔盐层、岩层的定性、定量问题,以及通过对井内盐岩层的解释来解决施工工艺问题。
The strata of rock salt are mainly composed of halite,gypsum,anhydrite,glauber salt,and concurrently carbonatite,sandstone and mudstone and other lithostratigraphic strata.Among them,carbonatite and mudstone can be a good cap rock and interlayer for the rock salt layer.These salt strata are of good geophysical characteristics,and the salt layer has a large difference with wall rock in physical characteristics.The main effective parametric curve of the salt layer is obvious.The geophysical logging method can effectively solve the problem of drilling in salt layer and qualitative and quantitative problems of the strata.In addition,the technology problem in construction can be solved through the explanation of the rock salt layer in the wells.
