Technical Field

The invention relates to the technical field of corrosion prevention of oil field pipelines, in particular to a temporary discharge device for a corrosion inhibitor filling port in batch processing operation of a sulfur-containing gas field.

Background

The gas in the raw material gas produced from a certain sulfur-containing natural gas field mainly contains components such as saturated steam, 2.7-8.44% of hydrogen sulfide by volume, 3.12-15.51% of carbon dioxide by volume and the like, and in addition, the pipeline adopts an improved moisture heating and heat preservation conveying mode, so that acid gas containing water, saturated steam, carbon dioxide and hydrogen sulfide can severely corrode a steel pipeline in the pipeline flowing process, and the pipeline needs to be protected.

In order to minimize the possibility of corrosion damage to pipeline equipment, the corrosion inhibitor is the most commonly applied and economically effective corrosion inhibition measure, so the application of the corrosion inhibitor is one of the key factors for ensuring the safe production of gas field development. The corrosion inhibitor is continuously filled in each single well station and gas gathering station in the sulfur-containing gas field, and the outside acid gas gathering and transportation pipelines between stations are regularly cleaned, pre-coated with the corrosion inhibitor and subjected to batch treatment, so that a layer of corrosion inhibitor oil film is added to the inner wall of the pipeline, and the protection effect of continuously filling the corrosion inhibitor is enhanced.

In the prior art, the Chinese patent number ZL201620689129.2 discloses a 'feed boiler pollution discharge device', the application date of which is 2016 (6-30) th year, and the publication date is 2016 (12-21) th year, and the utility model discloses a feed boiler pollution discharge device, which comprises a pollution discharge pool and a pollution discharge pipeline; the discharge end of the sewage discharge pipeline is horizontally suspended in the sewage discharge pool through the support, the support is arranged on the sewage discharge pool, the discharge end of the sewage discharge pipeline and an ascending pipeline form a three-way structure, discharge ports are formed in the two ends of the horizontal pipeline in a penetrating mode respectively, a damping spring is arranged on the discharge end sleeve of the sewage discharge pipeline, high-temperature high-pressure steam and sewage flow into the sewage discharge pipeline and then are discharged from the two discharge ports in a horizontal symmetrical mode respectively in two ways to enter the sewage discharge pool, reaction forces are offset mutually, and severe vibration of the sewage discharge pipeline is greatly reduced. Greatly reducing the damage of the sewage discharge pipeline, the fixing part and the sewage discharge pool.

However, the prior corrosion inhibitor filling device has the following problems in the practical application process: the existing corrosion inhibitor filling pipeline lacks a mechanism for manual release in time before overpressure, and dangerous conditions of pipeline explosion can occur; secondly, in the corrosion inhibitor batch processing operation process of pipelines outside the station, corrosion inhibitors are filled into the transverse filling pipes of the station, and when a coating slug is manufactured, a corrosion inhibitor filling port often cannot achieve real-time pressure monitoring of filling pipelines due to lack of pressure detection points, so that the risk of pipeline overpressure pipe explosion exists; the existing corrosion inhibitor filling pipeline has a single structure, the filling amount of the corrosion inhibitor cannot be measured, and the pipeline is easy to vibrate in the using process to cause adverse effects on the device; after the existing corrosion inhibitor filling device is filled, when a pipeline is dismantled, the corrosion inhibitor may overflow due to residual pressure in the pipeline, so that the environment is polluted, and a lot of corrosion inhibitors are wasted.
