轮南奥陶系潜山碳酸盐岩储层基质孔隙度和渗透率很低，但溶蚀孔洞的发育改善了其储集条件。
Matrix porosity and permeability are low in the Ordovician carbonate reservoirs of Lunnan buried hill, but the reservoir conditions are improved by the growing of dissolved pores.
对于裂缝性低渗透储层，由于其基质孔隙度小、渗透率低，天然微裂隙成为决定压裂液滤失的主要因素。
Micro fissure is a significant factor for determining the fluid loss in low-permeability fractured reservoir, due to its small porosity and low permeability in the matrix.
对比分析表明，NMR是基质孔隙度和束缚水评价的有效方法，常规测井与NMR的综合可以反映裂缝的影响。
Analysis of the contrast shows that NMR is an effective method of matrix porosity and irreducible water evaluation. The effect of fracture will be revealed by integrating conventional well logging...
