气体钻井岩屑返出系统检测系统设计 摘 要 随着气体钻井工艺在井场更多的被采用，如何更加准确的检测返出岩屑的质量成了生产中面临的一个问题。文章从气体钻井过程中返出岩屑本身的物理特性出发，分析其形态特点和影响因素，并对当前气体钻井返出岩屑质量测量的几种方案进行对比，结合微波法检测煤粉质量实例，初步建立微波法测量返出岩屑系统，最后对排砂管中气固两相流体进行动力学建模分析。 关键词：气体钻井；返出岩屑；流动力学；微波法  A detection system for the returned debris of gas drilling Abstract With gas drilling technology in well site more be adopted, how more accurate detection of returning cuttings quality into production in the face of a difficult problem. This article from the gas drilling in the course of returning the physical characteristics of the cuttings. Analysis the morphological characteristics and the influence factors, and the gas drilling return cuttings quality measurement of several schemes were compared, combined with microwave method was used to detect the quality of coal example, preliminary build microwave measurement returned debris system, finally, the sand discharging pipe gas-solid two-phase flow of kinetic modeling analysis. Keywords：Gas drilling；Returned Cuttings；Microwave；  目 录  TOC \o 1-3 \h \z \u HYPERLINK \l _Toc13524 第1章 引言  PAGEREF _Toc13524 1 HYPERLINK \l _Toc12001 1.1 课题的研究目的及意义  PAGEREF _Toc12001 1 HYPERLINK \l _Toc32720 1.2 国内外研究现状分析  PAGEREF _Toc32720 1 HYPERLINK \l _Toc25581 1.2.1 欠平衡钻井的定义  PAGEREF _Toc25581 1 HYPERLINK \l _Toc13896 1.2.2 气体钻井的定义  PAGEREF _Toc13896 1 HYPERLINK \l _Toc30929 1.2.3 气体钻井的分类  PAGEREF _Toc30929 2 HYPERLINK \l _Toc9045 1.2.4 国内外研究现状分析  PAGEREF _Toc9045 3 HYPERLINK \l _Toc12444 1.3 课题研究目标和研究内容  PAGEREF _Toc12444 4 HYPERLINK \l _Toc30911 1.3.1 研究目标  PAGEREF _Toc30911 4 HYPERLINK \l _Toc19744 1.3.2 研究内容  PAGEREF _Toc19744 5 HYPERLINK \l _Toc5007 第2章 气体钻井返出岩屑特点及影响因素  PAGEREF _Toc5007 6 HYPERLINK \l _Toc22458 2.1 返出岩屑的形态特点  PAGEREF _Toc22458 6 HYPERLINK \l _Toc24130 2.2 影响返出岩屑形态的因素分析  PAGEREF _Toc24130 7 HYPERLINK \l _Toc17726 2.3 本章小结  PAGEREF _Toc17726 8 HYPERLINK \l _Toc1406 第3章 岩屑返出系统检测系统设计  PAGEREF _Toc1406
