摘要
绝大多数碎屑岩储集层都含有粘土矿物,而且往往含有几种性质不同的粘土矿物。在不同地区,或同一地区不同的井,甚至同一井的不同井段,泥质或粘土矿物参数都可能有明显的不同。因此粘土矿物成分的变化,使测井解释和地层评价更加复杂化。在绥中1井区的研究中,根据不同的粘土矿物构成,对井段进行了划分,分别建立解释模型,提高了对地层孔隙度、渗透率和饱和度的计算精度。
The most of clastic reservoirs contained clay minerals,they often contained several different clay minerals.In different regions or different wells in the same area or even in different intervals of the same well,argillaceous or clay parameters might be significantly different.Therefore,in the study of Well Zhong I,according to the different clay mineral compositions,the wells are identified and models are established respectively for them,by which the precision of porosity,permeability and saturation calculations are improved.
