Problems solved by technology

Although the new polyguanidine fungicide can effectively kill all kinds of bacteria, this test in the laboratory can completely achieve the sterilization effect, but considering that the living environment of microorganisms in the mine is generally more complicated, a single polyguanidine fungicide has Sometimes it can't fully achieve the expected effect

Abstract

The invention relates to bactericide for oil fields, in particular to poly-guanidine SFT bactericide. The poly-guanidine SFT bactericide solves the technical problems of sterilizing and removing impurities in re-injection water in oilfields and waste water in oil refineries, and comprises the following raw material by weight in parts: 10-15 parts of hydrochloric polyhexamethylene guanidine, 2-4 parts of geramine, 5-7 parts of polyhexamethylene biguanidine, 1-3 parts of chlorine hydride guanidine, 2-4 parts of ferric sulfate and 20-30 parts of water. The poly-guanidine SFT bactericide can be adopted as the bactericide and water treatment agent of the re-injection water in the oilfields and the waste water in the oil refineries, not only has excellent anti-bacterial effect and sterilization effect, but also has a certain flocculate action, has no bubbles while being mixed with water, does not need de-foaming agent, and has good effects to accumulating oil, displacing oil and treating waste water.

Description

technical field [0001] The invention relates to a fungicide for oil fields, in particular to a polyguanidine SFT fungicide. Background technique [0002] Oilfield reinjection sewage generally has a high bacterial content, generally including sulfate-reducing bacteria, saprophytic bacteria, and iron bacteria. The massive growth and reproduction of bacteria will not only cause damage and blockage to the reservoir, affect the development effect, lead to a decrease in oil recovery, but also increase the pressure of the water injection well and increase the energy consumption of water injection. At the same time, the corrosion of surface pipelines, equipment and wellbore will be aggravated, which will eventually lead to the deterioration of the oilfield development effect, the increase of production cost, and the decline of the overall benefit, which seriously restricts the sustainable development of the oilfield. In order to overcome this problem, we adopt the method of adding ...
