技术领域technical field
本发明涉及油田管道技术领域，特别涉及一种电磁感应解凝数控线缆集油气系统。The invention relates to the technical field of oilfield pipelines, in particular to an electromagnetic induction decondensation numerical control cable oil and gas collection system.
背景技术Background technique
目前，非金属管道具有优良的耐腐蚀性和较低的水力摩阻，近几年在油气田开发地面工程建设中得到了较大规模的应用。在油田领域中，油田外围区块分散，地面建设环境差、远离老区且系统依托条件差，因此在寒冷气候下，对其开采不可能采用传统老区建站给水伴热的方式，只能采用电热集油工艺。而现有电热集油工艺只针对金属管道使用，随着非金属管道在油田上的大规模应用，非金属管道电伴热工艺将发展成为严寒地区低产油田实现单管集油，简化工艺，有效开发经济的一种有效技术措施。At present, non-metallic pipelines have excellent corrosion resistance and low hydraulic friction, and have been used on a large scale in the construction of oil and gas field development ground engineering in recent years. In the field of oil fields, the peripheral blocks of the oil field are scattered, the ground construction environment is poor, far away from the old areas, and the system support conditions are poor. Therefore, in cold climates, it is impossible to use the traditional way of water supply and heat tracing in the old areas, and only electric heat collectors can be used. oil craft. However, the existing electric heating oil collection technology is only used for metal pipelines. With the large-scale application of non-metallic pipelines in oil fields, the non-metallic pipeline electric heat tracing technology will develop into low-yield oil fields in severe cold regions to achieve single-pipe oil collection, simplify the process, and effectively An effective technical measure to develop the economy.
常规电伴热技术是以碳纤维电热线为发热源，实现加热保温集油。其基本结构是在管道外壁均匀缠绕具有耐高温绝缘护套的碳纤维电热线，再包覆导热膜和防腐胶带，然后以一次成型工艺制作硬质聚氨酯泡沫保温及聚乙烯黄夹克护套，两端配置接线盒后再以防水帽热缩密封。Conventional electric heat tracing technology uses carbon fiber electric heating wire as the heat source to realize heating, heat preservation and oil collection. Its basic structure is that carbon fiber heating wires with high-temperature-resistant insulating sheaths are evenly wound on the outer wall of the pipe, and then coated with heat-conducting film and anti-corrosion tape. After the junction box is configured, it is heat-shrink-sealed with a waterproof cap.
这种工艺已然在集油集气工艺上得到了广泛的应用，但是它还存在一些问题：（1）故障点查找难、处理速度慢。（2）电子元件易损坏。（3）长期运行故障率高，属于高耗能设备，后期管理难度大。传统的电伴热方式已严重制约了油田正常生产，电伴热集油工艺已成为影响生产的瓶颈，急需一种新的伴热技术来替代目前伴热方式。This technology has been widely used in oil and gas gathering technology, but it still has some problems: (1) It is difficult to find the fault point and the processing speed is slow. (2) Electronic components are easily damaged. (3) The long-term operation failure rate is high, which is a high-energy-consuming equipment, and the later management is difficult. The traditional electric heat tracing method has seriously restricted the normal production of oilfields, and the electric heat tracing oil collection process has become a bottleneck affecting production. A new heat tracing technology is urgently needed to replace the current heat tracing method.

下面具体描述一下该系统的工作原理：The working principle of the system is described in detail below:
（1）系统通电时，通过电磁感应，使得电磁波在钢铠内壁衰减，同时大部分电能以涡流形式转化为热能W1。(1) When the system is energized, the electromagnetic wave is attenuated on the inner wall of the steel armor through electromagnetic induction, and most of the electric energy is converted into heat energy W1 in the form of eddy current.
（2）在交变磁场作用下，在钢铠内壁感应产生磁滞损耗转换的热量W2。(2) Under the action of alternating magnetic field, the heat W2 converted by hysteresis loss is induced on the inner wall of the steel armor.
