摘要
钻井工程中发生井漏不仅严重影响安全、快速、低成本钻井,而且会严重污染矿层,影响矿层产量。开展漏失层位置测定方法与仪器的研究,对复杂地质条件下的钻井生产具有十分重要的意义。本文阐述了研发的CLY-1型多参数智能测漏仪的构成、参数采集过程、处理原理、仪器的机械结构和测试情况。采用多参数智能测漏系统的下探管直接接到钻杆或钢丝绳下端投放入孔进行测试,孔内探管沿孔深对泥浆流速(流量)、井温、井压、自然伽马等4种参量进行数值化测试,并将采集数据按一定格式存储到存储器中。探管从井中取出后,与地面电脑系统连接,将采集的数据存到存储器上形成数字文档,向相关人员提供漏涌判层的依据。
The occurrence of well leakage in drilling engineering not only seriously affects safe,fast,and low‑cost drilling,but also seriously pollutes the ore layer and affects its production.The research on methods and instruments for determining the location of leakage layers is of great significance for drilling production under complex geological conditions.This article elaborates on the composition,parameter acquisition process,processing principle,mechanical structure,and testing situation of the developed CLY-1 multi‑parameter intelligent leak detector.The lower probe tube of the multi‑parameter intelligent leak detection system is directly connected to the lower end of the drill pipe or steel wire rope and placed into the hole for testing.The inner probe tube in the hole performs numerical testing on four parameters such as mud flow rate,well temperature,well pressure,and natural gamma along the depth of the hole,and stores the collected data in a certain format in the memory.After the probe is removed from the well,it is connected to the ground computer system to store the collected data in memory to form a digital document,providing relevant personnel with the basis for identifying leakage and surge layers.
