Abstract
一种用于在井中的井下流量测量的方法，该方法包括：将光纤分布温度传感器(DTS)系统沿着井的流入区域长度的至少一部分安装；用传感器测量从地层流入井中的流体的温度波动和所述自然波动沿着下游方向流过井的速度。所测量的温度变化可为在0.1－0.5摄氏度之间的低频温度波动，该温度波动在井的流入区域的下游逐渐消失。
Description
技术领域
本发明涉及一种用于井中的井下流量测量的方法。
从国际专利申请WO01/75403中已知这样一种方法，在已知的方法中，通过将氮注入井中和使氮在所选定的井下冷却站(stations)处膨胀而在井管中形成一个或多个低温点(cold spots)。
纤维光缆(fibre optical cable)沿纵向延伸通过井，并被构造成为分布的温度传感器(”DTS”)，其中通过光缆传输一个和多个光脉冲，并且基于在反向散射的光信号中的拉曼峰值(Raman peak)的强度确定沿光缆长度的温度图形(temperature pattern)。在DTS系统中，利用反向散射信号的行程时间，以类似于雷达系统操作的方式确定反向散射信号的位置。
在已知方法中，DTS系统测量施加于每个冷却站处的低温点沿下游方向迁移通过生产管的速度。
已知方法的缺点在于在井中安装一个和多个冷却站以及氮或其它冷却流体供应管路是昂贵的，而且安装的这些设施是易碎的，由此容易损坏。
本发明的一个目的在于提供一种在井中的井下流量测量方法，其不需要在井下安装一个或多个冷却站和易碎的冷却流体供应管路。
本发明的另一个目的在于提供一种方法，用于测量沿着流入区域的至少一部分流入井中的流体流入量，流体从周围地层沿着该流入区域流入井中。
发明内容
根据本发明、用于井下流量测量的方法包括：将光纤分布温度传感器(DTS)系统沿着井的流入区域长度的至少一部分安装；使用该传感器测量从地层流入井中的流体的温度的一个或多个波动以及所述自然波动中的至少一个沿下游方向迁移通过井的速度。
令人惊讶地发现，流入井中的流体的温度存在波动，所述波动在产出的流体到达井口之前大致消失。所述温度波动通常很小，并且可能小于1摄氏度。
因此，优选的是，DTS系统被构造为追踪该向下流动具有小于1摄氏度、通常在0.1-0.5摄氏度之间的低频温度波动的通过井的向下游的迁移。
另外，优选的是，DTS系统沿着井的流入区域长度的至少相当部分延伸，并且该方法用来以所测量到的在纵向上的沿所述流入区域的长度的至少一部分上的流体速度的变化为基础，评估在沿着流入区域长度的不同位置处的流体流入流量。沿DTS测量间隔的沿下游方向的流体的固定流量通常表明没有流体流入测量间隔，而沿DTS测量间隔的沿下游方向的增加的流量通常表明沿DTS测量间隔的长度流体从地层流入并中。
根据本发明的方法可用于测量在烃类流体生产井中的井下流体流量和流入流量。
流入井中的流体可包括气态组分例如天然气和/或在流入区域中至少部分蒸发的组分。在这样的情况下，井的流体产量随着时间而周期性变化，以形成由气态和/或蒸发流体的膨胀和/或蒸发速度的变化引起的温度波动。在这样的情况下，可通过生产阻流或井下阀的打开的周期性变化或通过在井中或在井口下游的处理设备和/或生产流动管路中产生段塞流状态而使井的流体产量周期性变化。
在所附权利要求和摘要中对根据本发明的流量测量方法的这些和其它的特征、实施例和优点进行说明。
