Ferrochrome Lignosulfonate is used as oilfield chemicals

Ferrochrome lignosulfonate(Ferrochrome lignosulphonate) is widely used as fluid loss control agent used in drilling fluids with obvious ability to resist high temperature and salty solution.

In the process of oil production, various problems are encountered, which seriously affect the improvement of oil recovery rate and the quality of oil products, so a large number of chemicals are needed. Such as oil displacement agent, profile control agent, water blocking agent, sand control agent (including sand control bridge agent, sand control cementing agent, coupling agent), anti wax agent and wax removal agent, anti scale agent and descaling agent, clay stabilizer including clay anti swelling agent, clay particle anti migration agent), metal corrosion inhibitor, water treatment agent (including oil removal agent, flocculant, deaerating agent, fungicide), steam injection chemical agent, emulsified crude oil demulsifier (including oil-in-water emulsified crude oil demulsifier and oil-in-water emulsified crude oil demulsifier), tracers (including water tracer, oil tracer, gas tracer, oil-water distribution tracer), additives for acidification, fracturing fluid and fracturing additives, etc., which consume a huge amount.

Industrial lignin is rich in sources, low in price, biodegradable and pollution-free, and can be used as raw material to produce oilfield chemicals.

At present, the main oilfield chemicals produced by lignin at home and abroad are :

(1) drilling fluid, completion fluid, cementing fluid and treatment agent;

(2) Acidizing fluid, fracturing fluid and treating agent;

(3) Inject water and sewage treatment agent;

(4) water blocking agent and profile control agent;

(5) tertiary oil production chemicals;

(6)Oil and gas gathering and transportation chemicals;

(7) Corrosion inhibitor in drilling, mining and transport process; The chemical agent of oil layer protection.
