Abstract
1. Способ борьбы с парафиновыми отложениями в нефтегазовых скважинах, включающий спуск в насосно-компрессорные трубы устройства для нагрева добываемой жидкости, отличающийся тем, что в качестве устройства для нагрева добываемой жидкости используют технологическую колонну с обратным клапаном на конце, которую спускают на глубину ниже начала отложения парафинов на стенках труб, закачивают в колонну теплоноситель при работающей скважине, осуществляя ввод теплоносителя в поток добываемой жидкости до достижения добываемой жидкостью температуры на устье скважины не ниже температуры плавления парафинов. ! 2. Способ по п.1, отличающийся тем, что закачку теплоносителя осуществляют циклически или постоянно. ! 3. Способ по п.2, отличающийся тем, что при циклической закачке теплоносителя начало каждого цикла определяют по увеличению давления на приеме насоса и снижению дебита скважины по сравнению с установившимися значениями давления и дебита при работе скважины на технологическом режиме. ! 4. Способ по п.1, отличающийся тем, что в качестве теплоносителя используют, например, горячую воду, пар и другие агенты или их комбинации. ! 5. Способ по п.1, отличающийся тем, что на конце технологической колонны перед обратным клапаном устанавливают потокоотклоняющее устройство. 1. A method of combating paraffin deposits in oil and gas wells, including the descent into the tubing of a device for heating the produced fluid, characterized in that as a device for heating the produced fluid using a process column with a check valve at the end, which is lowered to a depth below the beginning paraffin deposits on the pipe walls, coolant is pumped into the column while the well is operating, entering the coolant into the flow of the produced fluid until the rate of production of the produced fluid perature wellhead not lower than the melting point waxes. ! 2. The method according to claim 1, characterized in that the coolant is pumped cyclically or continuously. ! 3. The method according to claim 2, characterized in that during the cyclic injection of the coolant, the beginning of each cycle is determined by the increase in pressure at the pump inlet and decrease in the flow rate of the well compared with the steady-state values of pressure and flow rate during operation of the well in a technological mode. ! 4. The method according to claim 1, characterized in that the heat carrier is, for example, hot water, steam and other agents, or combinations thereof. ! 5. The method according to claim 1, characterized in that at the end of the process column in front of the check valve, a flow deflector is installed.
