Technical Field

The invention relates to a natural gas exploitation technology, in particular to a novel adjustable unpowered alcohol injection device.

Background

Natural gas hydrate plugging is one of the problems often encountered during gas field production. For a gas production pipeline of a natural gas well site, because the gas composition in the pipeline is complex, the water content and the impurity content are high, and the pipeline is not deeply processed and treated, natural gas hydrate is easily formed in the pipeline under complex and variable flowing and external environment conditions. Once hydrate is formed, the local flow area of the pipeline is reduced, the pressure of a wellhead is increased, and the gas supply quantity of a downstream user is influenced. After a period of time, the blockage of the pipeline hydrate is aggravated, and in severe cases, blockage of pipeline cleaning balls, elbows, valves and other production equipment can be caused, and even production stop accidents of a gas field can occur. The problem of hydrate blockage is more and more important to be properly and scientifically treated because the problem is not only troublesome for the safe production of the gas field, but also influences the stable gas supply of a downstream gas unit and the normal operation of a gas collecting station and seriously hinders the development and production work of the natural gas field.

The conventional method for solving the hydrate blockage problem mainly comprises the following steps of heating, dehydrating, depressurizing, injecting hydrate inhibitor and the like:

1 traditional heat preservation. The traditional heat preservation mode is mainly through cotton + aluminium skin heat preservation of rubber and plastic, and the device is durable in use, and fire behaviour is good, and the coefficient of thermal conductivity is low, and no construction destruction can use decades, but when gas well gas production rate is more than or equal to 1000m year/d, the heat preservation effect reduces.

2 inhibitor instillation device. By the pumping principle, the medicine is regularly added into the pipeline, and the dripping amount is difficult to master.

3 infrared heating and heat preservation device. The device mainly relies on the heat radiation generated after the catalytic combustion of the natural gas to preserve heat, consumes the natural gas, effectively improves the heating quality, occupies small space and has high energy-saving effect. The device is big and need build the baking house to the natural gas consumption, has certain influence to constructions such as later stage flowing pressure gradient test.

4 heating furnace heating heat preservation device. The device adopts steam heating for heat preservation, and has high unit power. The device consumes natural gas and requires boiler support. The boiler belongs to a pressure container and has certain risks; the heating needs to be matched with the heat preservation for use and needs to be attended by personnel.

5 electric tracing heat preservation device. The device adopts heat tracing media to emit heat for heat preservation, has high heat efficiency, consumes electric energy, saves energy, has simple design, convenient construction and installation, no pollution and long service life, and can realize remote control and automatic control. The device is difficult to realize at the well site that some electricity conduction is inconvenient, and disposable input is high, needs periodic maintenance.
