摘要: 国内气体钻井施工过程已开始采用微波中继传输的方式构建随钻监控系统,但目前在该施工条件下应用的配套随钻监控软件不成熟,数据解析时间长,测传速率低且无信道监管功能,制约了气体钻井的发展。针对气体现场实际需要,采用事件驱动软件架构开发配套随钻监测软件,将气体钻井施工过程中各工程参数以曲线、数值、刻度等多种方式进行人机交互,并能对井筒内微波信道进行监管,为气体钻井随钻实时监控及钻后分析研究提供了软件支撑。并且该软件的应用大幅提升监测系统测传速率,其最大测传速率达到1.194 kb/s,信道监管功能的引入可增加入井微波中继器的数量,使测传深度突破3 000 m,基本满足目前气体钻井随钻监测的需要。

Abstract: Domestic gas drilling construction process has begun to use microwave relay transmission mode to build monitoring while drilling system. However, the supporting LWD monitoring software applied in this construction condition is not mature, the data analysis time is long, the measurement transmission rate is low and there is no channel monitoring function, which restricts the development of gas drilling. According to the actual needs of gas field, this design adopts event driven software architecture to develop supporting MWD monitoring software, which can conduct human-computer interaction of various engineering parameters in the process of gas drilling in various ways such as curve, value, scale, etc., and can supervise microwave channel in wellbore, which provides software support for real-time monitoring while drilling and post drilling analysis and research of gas drilling. Moreover, the application of the software greatly improves the test transmission rate of the monitoring system, and the maximum measurement transmission rate reaches 1.194 kb/s. The introduction of channel monitoring function can increase the number of microwave repeaters entering the well and make the logging transmission depth exceed 3 000 m, which basically meets the needs of current gas drilling while drilling monitoring.

    随着气体钻井的不断发展和最大储层接触钻井开发理念的提出,气体钻井技术与水平井等钻井技术相结合在致密低渗油气藏开发方面展现了巨大的潜力。但在气体钻水平井或特殊轨迹井的井眼轨迹测量、井眼轨迹控制技术领域仍然面临着一些关键的技术难题和挑战[1-3]

    针对气体钻井安全风险井下工况参数随钻获取难题,设计在井下监测出水、温度、井下压力、方位等工程参数的测量工具,有利于快速识别井下安全风险并及时采取控制措施,避免钻井安全事故,大大提高钻井成功率[4]。与此同时,针对目前井下数据传输效率低、可靠性差的难题[5],将钻柱作为微波信号通道,研制出高效可靠的信号传输系统,满足气体钻井井下安全监测和数据传输的需要[6]

    为了满足整个系统流程的需要,完成对气体钻井井下测量设备的监控,故研制配套的地面监控软件,不仅实现数据采集、分析观察,并能对监测到的井下情况并进行及时的评价处理[7-10]
