Evaluation of Biotoxicity of Drilling Fluid Treatment Agent and Drilling Fluid System in Bohai Bay
The environmental protection situation in China is becoming increasingly severe,and the environmental protection pressure in the process of oil and gas field development is increasing,how to ensure that the drilling fluid treatment agent and system are non-toxic,environmentally friendly,environmentally acceptable,minimize the amount of drilling waste,implement comprehensive utilization of waste,and meet the needs of drilling engineering safety,high quality,fast and efficient has become the development trend of drilling operations,and has received more and more attention.The biological toxicity detection test is a direct means to evaluate the prediction of the toxicity hazard of potential pollutants to the environment of a chemical substance or mixture,and the biotoxicity detection and evaluation of the commonly used drilling fluid treatment agent and system in Bohai Bay is carried out by luminescent bacteria method,which provides a reference and technical guarantee for the research and development of environmentally friendly drilling fluid and the optimization of treatment agent.
