电伴热工艺在低温时达不到防止水合物形成的作用,需要由注醇工艺保证正常生产,通过对电伴热+注醇工艺与完全注醇工艺进行对比,认为目前A气田更适合于电伴热+注醇工艺。但随着生产井的增多,甲醇消耗量增大,成本费用较高,若建立甲醇回收系统,对注入的甲醇回收循环利用,可以适应A气田快发展形势下高甲醇需求量,降低了生产成本,可以进行推广应用。
The electric heat tracing process can not achieve the function of preventing hydrate formation at low temperature, and the normal production is required by the alcohol injection process. By comparing the electric tracing + alcohol injection process and the complete alcohol injection process, it is considered that the current A gas field is more suitable for Electric heat + alcohol injection process. However, with the increase of production wells, the methanol consumption will increase and the cost will be higher. If the methanol recovery system is set up, the recovery and recycling of the injected methanol can meet the demand of high methanol under the rapid development of A field and reduce the production cost , Can promote the application.
