摘要

为解决在大庆油田工厂化压裂"即配即注"供液过程中,因水源水质中离子浓度变化而导致的压裂液交联性能降低的问题,开展了大庆油田工厂化压裂水源水现场检测处理技术研究。依据室内实验和现场施工要求,先用氢氧化钠法观察水源水是否有沉淀,然后加入净水剂利用絮凝原理消除不同离子,净化水源水质;现场快速检测净化后水源水配制的压裂液基本性能,验证了水源水净化质量,形成了工厂化压裂水源水检测处理技术。现场应用26口井,施工成功率达到了96.2%,平均单井增油量达到15t/d以上。该检测技术为压裂施工提供了良好的保障。
For the industrialized fracturing operation in Daqing Oilfield, fracturing fluid is prepared and then injected on site. In order to solve the problem of decreased cross-linking performance of fracturing fluid due to the change of ion concentration in source water in the process of fracturing fluid preparation & injection, field detection& treatment technology of source water for industrialized fracturing in Daqing Oilfield was researched. By combining the indoor tests with field applications′ requirement, firstly to observe whether there is precipitation in source water with sodium hydroxide method, then to add the water purification agent based on the flocculation principle to eliminate different ions, therefore, the quality of source water can be purified. Field rapid detection method can check the basic performance of the fracturing fluid prepared by the purified source water, and verify the purification quality of source water to form the detection & treatment technology of source water for industrialized fracturing. This technology has been applied to 26 wells with success rate of 96.2%, and the average daily oil production of individual well has been increased by more than 15t/d, which provides the favorable guarantee for fracturing operation.
