Abstract
The invention relates to seawater-based solid phase-free environment-friendly drilling and completion fluid. The seawater-based solid phase-free environment-friendly drilling and completion fluid comprises the following principal components: clean seawater, a salt-resistant tackified fluid loss additive, an anti-collapse inhibitor, a lubricating agent for the well drilling and completion fluid, a reservoir protective agent, a corrosion inhibitor for the well drilling and completion fluid, a pH value regulator and an antifoaming agent for the drilling and completion fluid; all the selected components of the drilling and completion fluid are environment-friendly additives; and the performance of the drilling and completion fluid is optimized. The drilling and completion fluid meets the requirements on the conventional performance of the drilling and completion fluid, such as density, acid-base property, filtration, rheology, stability and the like, and simultaneously has the advantages of high biodegradability, no biological accumulation, low toxicity or no toxin, no harm to environment and the like. The seawater-based solid phase-free environment-friendly drilling and completion fluid has an EC value of 6.6*10<5> mg/L and a core permeability recovery value of 93.5 percent, and the aims of protecting the reservoir, protecting the environment and improving the utilization rate of marine oil and natural gas resource are fulfilled..
