AI Technical Summary

Technical Problem

Existing horizontal directional drilling technology is difficult to effectively detect pre-existing utilities and prevent fracturing leaks and wedge holes, and lacks effective guidance and communication methods.

Method used

By monitoring drilling mud annulus pressure, drill bit force, and pilot hole parameters, and combining downhole and surface communication links, real-time detection and response to potential cross holes, fracturing leaks, and wedge holes are achieved. Lightweight locators and portable transceivers are used for depth measurement and guidance.

Benefits of technology

It improves the safety and accuracy of horizontal directional drilling, reduces damage to pre-existing facilities and environmental risks, and enables real-time monitoring and automatic adjustment.

Abstract

本发明描述了用于对检测到包括钻机和地埋工具在内的系统的有害操作状况启动响应的系统、装置和方法。该响应可以基于井上感测参数以及井下感测参数。有害操作状况涉及交叉孔检测、压裂漏出检测、过大的井下压力、喷嘴堵塞指示和钻柱楔孔检测。通信系统包括允许轻便检测器与钻机之间经由地埋工具进行双向通信的地埋通信链路。可以使用逼近积分值的技术进行地埋工具的深度和 / 或侧向运动的监测。在自动程序的背景下对基于自动刻槽的钻头力进行了描述。定位器至钻机的遥测的丧失可能触发自动切换到系统内的不同通信路径。
