The invention provides a method for constructing an oil drilling waste mud solidification pool and relates to the technical field of oil and gas exploration drilling pollution control. A scheme of the method comprises the following steps of: excavating the solidification pool on site, wherein the slope of a pool wall is 45 to 60 DEG, and the pool height is 2.0 to 2.5 m; performing seepage controlon a pool bottom by adopting clay-(non-woven geotextile)-(high-density polyethylene geomembrane)-(non-woven geotextile); continuously packaging solid waste to a top part by using the clay-(non-woven geotextile)-(high-density polyethylene geomembrane)-(non-woven geotextile); and capping the top part by using C20 concrete so as to prevent a solidified body from seeping. The process is simple and easy, the cost investment is small, the construction period is short, and the drilling waste mud is propelled to be solidified rapidly and timely so as to effectively prevent the waste mud from overflowing and polluting the environment in the drilling operation process.
