摘要(Abstract)：

本文分析了油层水淹前后碳酸盐含量及分布,并就注入水与水淹油层采出水的钙镁离子的含量、悬浮颗粒粒径及数量作了对比。油层水淹后,岩石中的钙没有被水溶解并带走,相反岩石中固体颗粒还有所增加,这对油层渗透性将发生不利影响。本文还分析了大量检查井岩心物性资料,结论是水淹油层岩石物性从总体上看没有发生明显变化。
The distribution of carbonate content before/after the reservoir is watered-out is analyzed in the paper. A comparision is made between the calcium, magnesium ion contents, the size and numbers of suspended particles in the injected water and those in the produced water from the watered-out reservoir. After the reservoir is watered-out, the calcium in rocks has not been dissolved in the water and carried away. On the contrary, the solid particles in the rocks increase. This is unfavourable to the permeability of the reservoir. A lot of data of rock properties from inspecting wells are also analyzed. As a result, it has been found that as a whole, no apparent changes in rock properties in the watered-out reservoirs have occured.
