随着生产的发展,人们对天然裂缝储集层的认识在不断提高。过去认为,原生粒间孔隙主要起储集作用,而次生缝洞主要起渗滤作用,两者含油性一致。测井分析的目的在于认识裂缝储集层,计算包括缝洞在内的孔隙度和含水饱和度,评价其含油性和生产能力。目前倾向于认为,缝洞与原生孔隙的含油性并不完全一致,原生孔隙也要有足够的孔隙性 With the development of production, people’s understanding of the natural fractured reservoirs continues to increase. In the past that the primary intergranular pores play a major role in the accumulation of secondary cracks mainly from the role of percolation, the two oil consistency. The purpose of well logging analysis is to recognize fractured reservoirs, calculate porosity and water saturation, including fractures, and evaluate their oil content and productivity. At present, the tendency is that the fractured pores are not completely consistent with the original pores, and the primary pores should also have sufficient porosity
