摘要
根据庄9井区大量的岩心观察以及室内试验，确定裂缝参数，选用RMS软件中的构造曲率法。建立考虑天然裂缝的地质模型；在此基础上，通过人为改变裂缝密度，采用注水模拟、流线模拟两种方法开展超低渗透油藏两种典型井网对裂缝适应性的研究。结论如下：①对于井距380m的小井距井网，不同裂缝密度对含水上升的差异性影响比较小，只要裂缝比较发育．含水上升就比较怏。②对于井距500m，排距140m的菱形反九点井网，裂缝密度含水上升的程度，初期影响不明显，在中后期影响比较大，裂缝密度小的含水上升慢，裂缝密度大的含水上升快；（④井距500m，排距140m菱形反九点井网对裂缝性油藏的适应性要好一些、
According to Zhuang 9 Well a lot of core observations and laboratory testing to determine the fracture parameters, use the software in the construction RMS curvature method, the natural cracks that take into account the geological model; On this basis, by artificially ehanging the crack density, use of water injection simulation , stream-line simulations are two ways to carry out two kinds of ultra-low permeability reservoir well spacing of cracks typical of adaptive researctl. Conelusions were as follows： ① the slim for the well 380m away from the well pattern, different fracture density differences on the impact of rising water is relatively small, as long as more cracks develop, water content increased relatively fast. ②For the well spacing 500m, from 140m of diamond-shaped row of anti-9：00 Well, the crack density, the rising water level, the initial impaet was not obvious, in the mid-and late impact of relatively large, the crack density of the water rose slowly, the water content increase in crack density, fast; ③ well away from the 500m, distance 140m diamond-shaped anti-9：00 Well the adaptability of the fractured reservoir is better.
