针对稠油井注汽热采过程中 ,一台锅炉同时注多口井时进入每口井的蒸汽流量和蒸汽干度不均的问题 ,设计了稠油热采注汽分配、计量、调节一体化装置。这种装置的分配器突破了传统的分支管的阻力平衡和空间的几何对称性结构 ,采用“分流分相式两相流体流量计”中的分流原理 ,对传流结构进行了改进 ;与之配套的新型两相流量计采用脉动噪音测量法 ,其测量元件仅为一块锐缘孔板 ;调节阀的阀心采用螺旋线型节流孔 ,具有易调节和调节稳定的特点 ;采用活动式橇装结构 ,安装和操作方便。装置有效地解决了吸汽困难井生产周期短产量低 ,吸汽好的井因吸汽量太多而损失热量的问题 ,节约了作业费用 ,提高了注汽井的热采效果。
Aiming at the problem of steam flow rate and steam dryness in each well entering one well while injecting more than one well at the same time in the process of steam injection and thermal recovery of heavy oil wells, the integration of heavy oil thermal recovery, injection and steam distribution, metering and regulation is designed Device. The distributor of this device has broken the balance of resistance and geometric symmetry structure of the traditional branch pipe. The shunt principle in “Split-flow split-phase two-phase flow meter” is adopted to improve the flow transmission structure; Supporting the new two-phase flow meter using pulsating noise measurement method, the measuring element is only a sharp edge of the orifice plate; control valve spool with spiral-type orifice, with easy to adjust and adjust the stability of the characteristics of the use of mobile sled Installed structure, easy installation and operation. The device effectively solves the problem of difficulty in absorbing steam, short production cycle, low production, good gas well, and heat loss due to too much gas absorption amount, saves the operation cost and improves the thermal recovery effect of the steam injection well.
