| 摘 要： | 水力压裂是低渗透油田开发的主要技术手段。油层岩石地应力的大小和方位决定了压裂裂缝的形态,对油田开发井网部署、工艺的选择有重要的意义。通过老油田加密井的岩芯实验,对重复压裂地应力的变化情况进行了分析,为水力压裂再造梳妆打扮裂缝,提高油层动用程度,改善油田开发效果提供了思路。 |

| Abstract: | Water fracturing is one main means for the development of low permeability oilfield.The size and orientation of oil layer ground stress decide the shape of fracturing crack,and take the key role in the distribution of well net and the selection of technology in the development of oilfields.Therefore,through the rock core experiment of closed-spaces wells in old oilfields,the changes of refracturing ground stress has been analysed,which provides some trains of thought for water fracturing to repair cracks,raises the extent of oil layer exploration and improves the effect of oilfield development. |
| Keywords: | water tracturing ground stress crack diverting crack test refi'acturing |
