英台油田在研究应用低温集油技术前全部为传统的三管伴随和掺输流程,能耗大,管线腐蚀结垢严重。在集输系统能耗构成中,单井集油能耗占73%,是集输系统能耗的主体,所以应用低温集油技术是降低集输系统能耗的主要途径。由于英台油田开发区块多,原油物性多样化,单井产液差别大,应用一种手段不能适应所有油井,通过产液分级、原油凝固点分析、不同区块粘壁温度分析,结合地温数据,界定出适合不同低温集油技术的油井条件,形成了常温输送、季节性常温输送、原油改性技术和定量低温掺输等多种技术,实现了优化简化、节能降耗的目标,减缓了管线的腐蚀结垢速率,为油田低温集油提供了参考。
Yingtai oilfield in the study before the application of low-temperature oil-gathering technology for all the traditional three accompanying and doping process, energy consumption, pipeline corrosion scale serious. In the energy consumption structure of gathering and transportation system, the energy consumption of single-well oil-gathering accounts for 73%, which is the main part of the energy consumption of the gathering and transportation system. Therefore, the application of low-temperature oil-gathering technology is the main way to reduce the energy consumption of the gathering and transportation system. Due to the large number of oil and gas fields in Yingtai Oilfield and diversified crude oil physical properties, there is a large difference in single well liquid production. By using one method, it can not be adapted to all oil wells. Through analysis of liquid production grade, crude oil solidification point analysis, temperature analysis of viscous wall in different blocks, , Define well conditions suitable for different low-temperature oil-gathering technologies and form a variety of technologies such as room temperature transport, seasonal room temperature transport, crude oil modification technology and quantitative low-temperature mixing to achieve the goal of optimization and simplification, saving energy and reducing consumption Corrosion rate of pipeline fouling, oilfield oil provides a reference for low temperature.
