摘要: 國內氣體鉆井施工過程已開始采用微波中繼傳輸的方式構建隨鉆監控系統,但目前在該施工條件下應用的配套隨鉆監控軟件不成熟,數據解析時間長,測傳速率低且無信道監管功能,制約了氣體鉆井的發展。針對氣體現場實際需要,采用事件驅動軟件架構開發配套隨鉆監測軟件,將氣體鉆井施工過程中各工程參數以曲線、數值、刻度等多種方式進行人機交互,并能對井筒內微波信道進行監管,為氣體鉆井隨鉆實時監控及鉆后分析研究提供了軟件支撐。并且該軟件的應用大幅提升監測系統測傳速率,其最大測傳速率達到1.194 kb/s,信道監管功能的引入可增加入井微波中繼器的數量,使測傳深度突破3 000 m,基本滿足目前氣體鉆井隨鉆監測的需要。

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.
Key words : gas drilling;while-drilling monitoring;microwave relay transmission;data processing;monitoring software

0 引言

    隨著氣體鉆井的不斷發展和最大儲層接觸鉆井開發理念的提出,氣體鉆井技術與水平井等鉆井技術相結合在致密低滲油氣藏開發方面展現了巨大的潛力。但在氣體鉆水平井或特殊軌跡井的井眼軌跡測量、井眼軌跡控制技術領域仍然面臨著一些關鍵的技術難題和挑戰[1-3]

    針對氣體鉆井安全風險井下工況參數隨鉆獲取難題,設計在井下監測出水、溫度、井下壓力、方位等工程參數的測量工具,有利于快速識別井下安全風險并及時采取控制措施,避免鉆井安全事故,大大提高鉆井成功率[4]。與此同時,針對目前井下數據傳輸效率低、可靠性差的難題[5],將鉆柱作為微波信號通道,研制出高效可靠的信號傳輸系統,滿足氣體鉆井井下安全監測和數據傳輸的需要[6]

    為了滿足整個系統流程的需要,完成對氣體鉆井井下測量設備的監控,故研制配套的地面監控軟件,不僅實現數據采集、分析觀察,并能對監測到的井下情況并進行及時的評價處理[7-10]
