Abstract
在天然气开发过程中,需要进行试气对井内气体组分、组成进行精确测试才可进行后续开发工作。目前,天然气井的试气手段多为井下或井口采样送检,由于井下储层条件具有温度、压力的波动,所得到的检测结果不能准确表征井下气体状态。本发明公开了一种电缆传输井下激光拉曼测试工具,该工具利用激光拉曼光谱完成井下天然气组成、组分的测定,并通过电缆实时传输方式进行不同井段数据处理,简化试气过程中采样、实验室实验及分析流程,达到现场原位测试目的。
Description
技术领域
本发明涉及井下试气及光谱成像技术领域,具体的说是一种利用激光拉曼光谱进行井下原位试气的电缆传输井下激光拉曼测试工具。
背景技术
目前,气井的试气手段为井下或井口采样送检,由于井下储层条件具有温度、压力的波动,所得到的检测结果不能准确表征井下气体状态。激光拉曼光谱分析技术已经在天然气分析领域得到广泛测试及应用,基于激光拉曼原理的气体分析技术具有实时分析、可以表征待测气体结构信息、对干扰不敏感、无需复杂预处理及可同时分析多种气体等优点,被广泛地应用于气体组成分析及气体分子结构分析等气体分析实验中,如气体分析系统及电缆传输井下激光拉曼测试工具(申请号:201811643538.9)、一种集成反射和透射的拉曼线扫描高光谱成像系统(申请号:201910021884.1)。
现有试气工具在测试过程中无法满足原位试气,现有激光拉曼测试工具也停留在实验室内检测,所以,本发明所述测试工具可在井下在基于激光拉曼气体分析原理,在井内原位使用检测光照射到被分析气体上会发生拉曼散射,拉曼散射散射光被成像系统接收,通过电缆传输回地面控制电脑以对被分析气体进行分析。
发明内容
基于此,针对上述问题,提供一种电缆传输井下激光拉曼测试工具,能够进行井下原位气体实时测试,得到井下气体组分组成。
一种电缆传输井下激光拉曼测试工具,包括:采用激光发射器、二向色镜、光栅、气腔、棱镜、反射镜及分管器和成像系统组成激光拉曼测试工具,所述测试工具激光发射器、二向色镜、光栅及反射镜在气体出口端一侧,棱镜及反射镜在气体入口端一侧,所述模式可以更加高效进行激光拉曼检测。
本发明所采用的技术方案是,利用电缆或穿电缆连续油管将该测试工具下入井内预定位置,控制开启气泵使井内气体循环至气腔中,同时开启激光拉曼测试系统进行实时多次检测,收集到的测试数据实时通过电缆传输回地面进行数据分析。
与现有试气手段相比,本发明的有益效果是能在不同井况下进行实时原位测试,不需要经历采样、样品制备、实验室送样、测试流程,同时利用激光拉曼光谱学技术,将检测结果及精度提高,避免无效测试。
