三、使用方法
Ⅰ、本产品首次使用时，应先预膜，加注可采用连续和间歇两种方式。对于含硫生产气井（无分隔器）建议由套管环空加注，经油管返出形成一定循环体系；对于常关气井建议分别从油、套管加入；对于油气集输管线可直接加注。
Ⅱ、预膜用量计算方法：
1、预膜面积：按气井油管内、外表面积+套管内表面积+拟保护地面管线内表面积；
2、预膜厚度：75μm。
Ⅲ、气井建议周期性间歇加注，推荐加药周期为30天，每次加量为80㎏。
油井建议连续性加药，推荐用量：按产出液计算，推荐使用浓度200ppm。
四、包装、运输与贮存
包装：200L塑料桶包装，净重200±1kg。
运输：防日晒、雨淋，应避免与腐蚀性物品和尖状物品混运。
贮存：置于干燥、通风库房，避免与腐蚀性的物品混放，保质期1年。
五、安全与防护
皮肤与眼睛接触：立即用大量清水冲洗。
误食：饮足量温水，催吐，就医。
操作保护：戴PVC、PE或橡胶手套。
泄漏：用大量清水冲洗。
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
Ⅰ、 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.
Ⅱ、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.
