Chemicals For Oilfield Water Treatment

Use

In the process of oil and gas exploitation, due to the combined action of high flow and various corrosive media, casing and surface pipelines are subjected to unusually severe corrosion and abrasion, which leads to the shortening of equipment life, affects the production of oil Wells and causes huge economic losses.

Indirect injection of liquid corrosion inhibitor has been widely used in oil fields for a long time, which has encountered the following problems:

1. Oil and gas Wells produce large quantities of liquid and high flow rate, the liquid corrosion inhibitor added is easy to be quickly carried out, and the effective protection period of corrosion inhibitor is short;

2. The liquid corrosion inhibitor added from the oil jacket annulus is difficult to reach the well section below the operating valve, and 30%-50% of the string is not protected;

3. Adding liquid corrosion inhibitors requires the use of high-pressure column liquid pumps, containers and pump trucks and other ground equipment measures, which is difficult to manage. Moreover, the dosage is uneven, the drug consumption is large, the dosage workload is large, the dosage is not easy to control, and the effect is unstable.

4. For a well with a packer, the interval below the packer cannot be protected;

5. For edge Wells, it is inconvenient to use.

The product is a composition that provides a multi-effect solid corrosion and scale inhibition rod to solve the above problems existing in the prior art. The scale inhibition rod formed by this composition has the comprehensive effect of slow release corrosion inhibition, wax prevention and scale inhibition, and has a large range of pipe column protection; Low cost, stable effect; It has the effect of slow release, corrosion inhibition, scale inhibition and wax prevention; Convenient on-site dosing.
