Potassium formate is an environmentally friendly, harmless and non-toxic drilling fluid
The process of petroleum exploration and development consists of many stages of different nature and tasks. In oilfield development, there are several stages of exploration, construction and production. Each stage is related to each other, and a lot of drilling work is needed. Potassium formate drilling fluid is a drilling fluid that can meet the requirements of environmental protection while meeting the requirements of oil and gas field drilling engineering.
Potassium formate drilling fluid is characterized by its anti-collapse performance, inhibition performance, environmental protection, reservoir protection, high temperature resistance, pollution resistance, low corrosiveness and recyclability.
Formate drilling fluid system is composed of alkali metal salt of formic acid, polymer tackifier and filtrate reducer. Without solid weighting agent, the density of the system can reach 2.3g/cm3, which is easy to realize solid-free drilling or low solid-phase drilling; low viscosity, good fluidity, low friction; strong inhibition, stable borehole wall and regular borehole diameter; Genus, rubber and other corrosive, recyclable, reusable, since the successful test in 1995 in the drilling industry has achieved good application results.
Potassium formate drilling fluid is more acceptable to the environment than conventional salt water system. The experiments on aquatic organisms show that both sodium formate and potassium formate can be classified as non-toxic, while cesium formate can be classified as non-toxic. So potassium formate can be degraded quickly when diluted by water. It can only exist in water for a short time. Biodegradation experiments show that all formates with biodegradability of more than 70% in 28d can be classified as "biodegradable" substances.
In different stages, the purpose and task of drilling are different. Drilling fluid is a kind of circulating fluid which can meet the needs of drilling work with its various functions in the process of oil and gas drilling. Drilling fluids often contain crude oil, diesel oil, various oils and a large number of chemical treatment agents. In order to prevent the possible impact of drilling fluids on the environment and ecology, harmless and harmless drilling fluids are required. So potassium formate drilling fluid can meet the requirements of environmental protection.
