智能钻井技术研究

Study of intelligent drilling technology

石油钻井技术发展的总趋势是以信息化、智能化、自动化为特点,最终实现自动化钻井。智能钻井不仅仅是自动化钻井,广义的来讲,就是将人工智能的理论、方法和技术应用于钻井过程,使其具有类似人工智能特性或功能。详细介绍了智能钻井的四大关键技术——地面计算机智能专家系统、井下智能工具、井下供电装置、提供高速双向数据传输的通讯网络系统。探讨了如何对常规的钻井系统进行技术改造,使之具有数据采集、数据传递、数据分析、指令执行这四项智能钻井系统具有的功能,指出当前最为可行的智能钻井系统方案是电力驱动的连续油管智能钻井系统,为现阶段智能钻井技术的研究指明了方向。

The general trend of oil drilling technology is characterized by information, intelligence and automation,and ultimately achieve the goal of automated drilling.Intelligent drilling is not only Automation.Broadly speaking,it is also applying the artificial in- telligence theory, methods and techniques in the process of drilling so that it will have similar characteristics or function of artificial intelligence.Presented four key technologies of intelligent drilling in details,which are intelligent computer expert system on the ground, intelligent downhole tools, downhole power device, communication network system providing a two-way high-speed data transmis- sion.Discussed on how to reform conventional drilling systems so that they are endowed with data acquisition, data transmission, data analysis, instruction execute features. At last, pointed out that the most feasible drilling system is intelligent power-driven coiled tubing drilling system at present.This paper indicated the right direction for intelligent drilling technology research at the moment.
