摘要
通过对两区块储层充填胶结物特征、阳离子交换容量、孔隙结构特征与物性、地层微粒等地质特征的分析,确定了储层潜在的敏感性,即水敏、速敏、酸敏。继而通过室内一系列岩心流动试验,证明了上述敏感性问题的存在及其敏感性的程度。最后提出了储层保护的几点建议。
Reservoir formation in Lun16 and Lun35,Baise basin is characterized by medium-low permeability,heterogeneous,and with relatively higher clay mineral content.Therefore,a study of reservoir sensitivity as well as its protection before its development will be very important.An analysis of the geological characteristics:Cementing materials in the reservoir,cation exch- ange capacity,pore structure,petrophysical properties,and fine particles …etc.determines the potential reservoir sensitivity:water-,velocity-and acid-sensitivites.A seccessive series of laboratory tests demonstrates the presence of above-mentioned sensitivities and their relative effects.Finally,some protective means are suggested.
