摘要(Abstract)：

压驱试验通过在试验井目的层段压裂形成人工裂缝，同时注入大量驱替液，使目的层段渗流能力增强，地层能量得到补充，达到较好的增液、增油效果，注入过程具有高压力、高排量以及边造缝边滤失的技术特点。为防止压驱裂缝与邻井直接连通形成无效循环通道，研究了压驱时邻井压力实时监测配套工艺及压力预警方法。从压力实时监测井点、监测时机、监测仪器3方面进行了监测方案优化。综合考虑压驱时监测井与压驱井的井距、连通关系，监测压力上升速率、上升幅度、耐压指标等参数，建立了压力预警机制，并编写预警推送软件，实现压力预警信息的自动推送。通过现场实践应用证实，该方案及配套监测技术能满足压驱试验需求，保障了压驱施工的安全高效运行。
In fracturing flooding test,artificial fractures are formed in the target intervals of the testing well with a large amount of displacing fluid injected.The flow capacity of the target interval of the testing well is enhanced,the formation energy is supplemented,and much better effects of increasing fluid and oil are achieved after taking the measures.The injecting process is characterized technically by high pressure,high discharge and fractures initiation with fluid loss simultaneously. In order to prevent hydraulic fractures from directly connecting with adjacent wells and causing invalid circulating channel,a supporting technique of real-time pressure monitoring of adjacent wells and pressure warning are studied. The monitoring scheme is optimized from 3 aspects of real-time pressure-monitoring well points,monitoring opportunity and monitoring instrument. Considering the well spacing and connectivity between monitoring wells and fracturing wells,as well as pressure rise rate,rise range,pressure-resistant index and other parameters,a pressure warning mechanism is established. An early warning push software is compiled to realize automatic push of pressure warning information. Field application shows that the scheme and its supporting monitoring techniques can meet the requirements of fracturing-flooding test and ensure the safe and high-efficiency operation of fracturing and flooding.
