FIELD: oil-and-gas industry. ^ SUBSTANCE: invention may be used at discharge pipelines not equipped with cleanout device "in-out" chambers that transfer coagulating wax oils. Chamber with gel piston with diameter making, at least, that of discharge pipeline and length of, at least, 0.1 of pipeline length, is jointed to pipeline end face to force therein the gas compressed to pressure P defined by the formula where ä is initial oil shift stress, L and D are pipeline length and diameter, respectively; Pk is pipeline pressure at joint with oil collection hardware (collector, cluster measurement unit). ^ EFFECT: higher quality of oil line cleaning and prevention of pipeline freezing. ^ 1 dwg |
