偏心分层注水井一体化验封测调工具研制

大庆油田先后开发了电动测调、电动验封等技术,大幅度提高了分层注水的测试效率。但是,电动测调和电动验封均属于独立技术,测试时需要操作人员分别使用测调仪、验封仪,进行多次起下操作,增加了仪器成本、人工成本和测试车辆费用。为了进一步提高测试效率、降低成本、增强对地层特性的认识,研制了偏心分层注水井的一体化验封测调工具。该工具由验封测调一体仪和地面控制系统组成。地面控制系统下发测试命令,主要实现与验封测调一体仪的单芯供电、通讯功能; 验封测调一体仪主要实现压力、温度、流量等信号的采集处理、单芯通讯、电机控制等功能。该工具实现了一次下井分别完成验封工作和测调工作,满足油田精准开发、降本增效的需求。

Development of the Integrated Seal Checking and AdjustmentTool for Eccentric Stratified Injection Well

Daqing oilfield has developed and applied electric testing and sealing technology, which greatly improved the test efficiency of layered water injection. However, both electric test and electric seal inspection are independent technologies. During the test, operators are required to use test and seal inspection instruments to carry out multiple starting and closing operations, which increases the cost of instruments, labor cost and test vehicle consumption. In order to improve the testing efficiency, reduce the input and enhance the understanding of the formation characteristics, an integrated of check seal test and adjustment tool for the eccentric stratified injection well was developed. The tool is composed of two parts, an instrument for check seal and adjustment and a ground control system. The ground control system issues the test command, which mainly realizes the power supply and communication function of the single core with the instrument of inspection, sealing, test and adjustment. The instrument mainly realizes the collection and processing of pressure, temperature, flow and other signals, single-core communication, motor control and other functions. This tool realizes the completion of inspection and sealing work and test and adjustment work, and meets the needs of accurate development, cost reduction and efficiency improvement of oilfield.
