本文阐述了压裂措施情况、压裂措施效果及压裂措施应用的意义,运用具体问题具体分析的方法,利用测试跟踪、动态分析、现场跟踪等手段,通过分析2009年高台子油井的压裂效果情况,发现油井的压裂效果的好坏与施工过程的质量以及连通水井的注入状况有关。压裂后对地层也产生一定的影响,压后的注水压力有很大幅度下降,静压有所上升,流压有所上升,生产压差、总压差减少。同时还总结出要获取一口井好的压裂效果,必须做好压裂井压前的准备、压裂施工工程中的质量监督和压裂后的强化管理。压前,要对压裂井周围所连通的井进一步完善注、采系统,做好对应连通压裂层段的提压、增注工作,恢复和提高油层压力。压裂后造成的地层高压现象应采取适当的方法来缓解,对于油井关井的其连通的水井也要相应的控注,以上措施对防止套变的发生,都有着重要的意义。
This paper describes the situation of fracturing measures, the effect of fracturing measures and the significance of the application of fracturing measures. By means of concrete analysis of specific problems, this paper analyzes the fracturing of Gaotaizi well in 2009 by means of test tracking, dynamic analysis and on-site tracking. The results show that the fracturing effect of the well is related to the quality of the construction process and the injection status of the connected well. After fracturing, it also has certain influence on the formation. The pressure of water injection after pressure reduction has greatly decreased, the static pressure increases, the flow pressure increases, the production pressure difference decreases, and the total pressure difference decreases. At the same time, it is also concluded that in order to obtain a good fracturing effect in a well, it is necessary to prepare well before fracture fracturing, quality supervision in fracturing construction and intensified management after fracturing. Before the pressure, we should further improve the injection and recovery system of the well connected around the fracturing well, and make the corresponding pressure rise and injection work of the connected fracturing section to restore and raise the pressure of the reservoir. The formation pressure caused by fracturing should be taken appropriate measures to mitigate, for wells connected wells connected well should also be the corresponding control injection, the above measures to prevent the occurrence of sleeve sets are of great significance.
