摘要:
自动化压井是指计算机能够按照一定的控制原则独立完成压井的1种方法。为了验证自动化压井系统的可行性和平稳性,开展了多种不同程度的试验井气侵模拟,利用自动化压井系统进行司钻法自动化压井操作试验,成功实施了司钻法第1循环周压井。研究结果表明:自动化压井系统能够实时获取和分析溢流参数,迅速准确生成压井施工单,对节流控制箱实施远程控制并完成节流阀开度的调整;在不同气侵程度下,自动化压井系统能够按照压井设计曲线将立压稳定控制在目标值附近;在气侵气体向上运移和排出井口的过程中,井底压力波动远小于人工压井所产生的压力波动。该项研究基本验证了自动化压井系统在钻井井场应用的可行性。
Abstract:
The automatic well killing is a method that the computer can complete the well killing independently according to certain control principles. In order to verify the feasibility and stability of the automatic well killing system, a variety of simulation on gas invasion in the test wells with varying degrees were carried out, then the automatic killing system was applied to carry out the automatic killing operation tests of driller’s method, and the 1st circulation circle well killing of driller’s method was implemented successfully. The results showed that the automatic well killing system could obtain and analyze the kick parameters in real time, generate the well killing sheet quickly and accurately, control the choke control box remotely and complete the adjustment on opening degree of choke valve. Under different gas invasion degrees, the automatic well killing system could control the stand pipe pressure stably close to the target value according to the well killing design curve. In the process of upward migration and discharging wellhead of the gas invasion influx, the pressure fluctuation at well bottom was much less than that produced by the manual well killing. The feasibility of applying the automatic well killing system in the drilling well site was verified basically by this study.
