摘要
近年来,页岩气的商业开发使得传统意义上只能作为烃源岩或盖层的泥页岩有了新的定位——储集层,许多将泥页岩作为储集层的基本问题也被相应地提了出来。其中,孔隙度问题在常规储层中就至关重要,在泥页岩研究中自然不容忽视。不少学者对于泥页岩孔隙度的确定问题提出了自己的计算方法。文中选取了较为典型的岩石物理模型法和岩心刻度测井法,对东营凹陷牛38井沙三下亚段及郝科1井沙四上亚段泥页岩的孔隙度进行了计算,2种方法所得结果与实测值基本一致,从而验证了这2种方法的正确性;同时,根据计算过程及结果,分析说明了2种方法的优缺点。
In recent years, with the commercial development of shale gas, shale, the traditional hydrocarbon source rocks or cap rock, has a new role： reservoir. Many questions about this issue have been raised accordingly. Porosity, as a very important parameter in conventional reservoir, should not be ignored. Recently many scholars propose calculation methods for mud shale′s porosity. This article selects two typical methods, rock physics model method and core calibration logging method, to calculate the porosities of mud shale in lower Es3 section of Well Niu 38 and upper Es4 section of Well Haoke 1. The results of the two methods are basically identical with the actually measured values, the advantages and disadvantages of the two methods are illustrated.
