摘要:
為了解決鉆井工程產生的大量數據缺乏有效分析處理和深入挖掘的問題,并實現井場與基地及時的技術互動與遠程支持,開展了鉆井輔助決策系統的研究與構建。實時動態的鉆完井數據庫以鉆井模擬器為核心,集成了耦合水動力模型、摩阻與扭矩模型、鉆速優化模型等鉆井工程計算模型,實現鉆井過程的實時動態模擬、三維可視化、遠程鉆井監控。通過渤中19-6 勘探項目9 口井的應用,結合摩擦因數反演法、水力模型擬合法以及階段校正等方法,最終實現了摩阻與扭矩、水力參數模擬精度90%、地層孔隙壓力監測精度97% 的準確度,開展了累計20 余次的遠程專家會診技術支持工作,最終建立了一套基于數據瞬態模擬分析的遠程鉆井輔助決策系統結構與工作方法。
Abstract:
Abundant data generated by drilling engineering is not analyzed and processed effectively and the related problems are not researched thoroughly. In addition, well sites and bases are lack of timely technical interactivity and remote support. In order to solve these problems, an assistant decision-making system for well drilling was established. Then, a real-time dynamic drilling and completion database was studied and newly built, and the drilling engineering calculation models (e.g. coupled hydrodynamic model, friction and torque model and ROP optimization model) were integrated with drilling simulator as the core, and thus real-time dynamic simulation, three-dimensional visualization and remote drilling monitoring in the process of drilling is realized. Finally, based on its application in 9 wells of BZ19-6 exploration project, combined with friction coefficient inversion method, hydraulic simulation fitting method and stage correction method, the simulation accuracy of friction and torque and hydraulic parameter was 90% and the monitoring accuracy of formation pore pressure was 97%. What’s more, remote technical support based on expert consultation has been carried out accumulatively over 20 times. And eventually, a set of structure and method of remote assistant decision-making system for well drilling based on transient data simulation analysis was established.
