油氣集輸緩蝕劑

一、產品概述

油氣井采出液中的CO2、H2S、CI等腐蝕介質含量較高,對套管、油管造成嚴重腐蝕,本產品是以咪唑啉季銨鹽類衍生物、雙咪唑啉、醛酮胺縮合物等緩蝕組分和其他輔助組分復配構成的液體緩蝕劑,具有緩蝕率高、凝固點低、分散性好、熱穩定性好、低毒等優點,可迅速在金屬表面形成致密牢固的保護膜,對多種腐蝕因素都有較強緩蝕性能。本產品與其它井下用劑具有良好的配伍性。

三、使用方法

  Ⅰ、本產品首次使用時,應先預膜,加注可采用連續和間歇兩種方式。對于含硫生產氣井(無分隔器)建議由套管環空加注,經油管返出形成一定循環體系;對于常關氣井建議分別從油、套管加入;對于油氣集輸管線可直接加注。 

 

Ⅱ、預膜用量計算方法:

1、預膜面積:按氣井油管內、外表面積+套管內表面積+擬保護地面管線內表面積;

2、預膜厚度:75μm。

Ⅲ、氣井建議周期性間歇加注,推薦加藥周期為30天,每次加量為80㎏。

油井建議連續性加藥,推薦用量:按產出液計算,推薦使用濃度200ppm。

 

四、包裝、運輸與貯存

    包裝:200L塑料桶包裝,凈重200±1kg。

    運輸:防日曬、雨淋,應避免與腐蝕性物品和尖狀物品混運。

     貯存:置于干燥、通風庫房,避免與腐蝕性的物品混放,保質期1年。

 

五、安全與防護

 皮膚與眼睛接觸:立即用大量清水沖洗。

 誤食:飲足量溫水,催吐,就醫。

 操作保護:戴PVC、PE或橡膠手套。

 泄漏:用大量清水沖洗。



Oil and Gas Pipeline Transmission System

Corrosion Inhibitor

Product Overview

In the oil and gas well produced fluid CO2 and H2S、CI - corrosive medium, such as content is higher, causing serious corrosion of casing, tubing.This product is imidazoline quaternary ammonium salt derivatives, double imidazoline, aldehyde, ketone condensation product of amine and other components of the corrosion and other auxiliary components distribution of liquid in the composition of the corrosion inhibitor. This product has the advantages of high corrosion inhibition rate, low freezing point, good dispersion, good thermal stability, low toxicity and so on. This corrosion inhibitor can quickly form a tight and firm protective film on the metal surface, and has a strong corrosion inhibition performance against a variety of corrosion factors.

This product has good compatibility with other downhole agents.

Methods used

、 When the product is first used, the film should be prefabricated. Continuous and intermittent injection can be used. For sulfur-bearing production gas Wells (without separators), it is suggested to refill by casing annulus and return through tubing to form a certain circulation system. It is suggested to add oil and casing respectively to the normally closed gas well.For oil and gas collection and transportation pipelines can be directly injected.

 、Calculation method of prefilm dosage:

1.    Pre-film area: the sum of the internal and external area of gas well tubing, the surface area of casing and the surface area of the pipeline to be protected;

2.    Thickness of prefilm:  75 microns.

3.    Gas well recommended periodic intermittent filling, recommended dosing period of 30 days, added amount 80 ㎏ each time.

Continuous dosing is recommended for oil Wells. Recommended dosage: calculated according to the output fluid, the recommended concentration is 200ppm.

Packing, Transportation 、Storage

Packing: 200L plastic drum, net weight 200kg.

ransportation: avoid sunburn and rain. Avoid mixed transportation with corrosive and sharp articles.

Storage: store in dry and ventilated warehouse, avoid mixing with corrosive materials, with a shelf life of 1 year.

Safety & amp; protection

Skin to eye contact: rinse immediately with plenty of water.

Ingestion: drink enough warm water, induce vomiting, seek medical advice.

Peration protection: wear PVC, PE or rubber gloves.
