Description
Изобретение относитс к нефтегазо:добывающей промышленности, в частности к способам удалени жидкости с забо скважин. FIELD OF THE INVENTION The invention relates to the oil and gas: extractive industries, in particular, to methods for removing fluid from a well bottom.
Известен способ удалени жидкое- . ти с забо газовой скважины путем продувки скважины в атмосферу 1.A known method for removing liquid is. ti from the bottom of a gas well by blowing a well into the atmosphere 1.
Недостаток этого способа состоит в трм, что по мере падени пластовой энергии скорость восход щего потока газа становитс недостаточной дл выноса жидкости из скважины.The disadvantage of this method lies in the use of trm, that as the formation energy falls, the speed of the upward flow of gas becomes insufficient for the removal of fluid from the well.
Наиболее близким к предлагаемому техническому реигению вл етс способ удалени жидкости, вкдйчакадйй введение в удал емую жидкость твердого пенообразующего ПАВ 2 .Closest to the proposed technical remediation is a method of liquid removal, including the introduction of solid foaming surfactant 2 into the liquid to be removed.
Недостатком данного способа вл етс низка эффективность удалени жидкости при наличии зумпфа в скважине .The disadvantage of this method is the low efficiency of fluid removal in the presence of a sump in the well.
Целью изобретени . вл етс повышение эффективности удалени жидкости .The purpose of the invention. is an increase in fluid removal efficiency.
. Эта цель достигаетс тем, что согласно способу удалени жидкости с газовой скважины ПАВ удерживают у подошвы продуктивного пласта на .кольцевой сетчатой манжете,установленно1й На насосно-компрессорных трубах,ймеющих в интервале.продуктивного пласта сквозные отверсти , суммарна площадь которых равна или больше площади проходного сечени труб.. This goal is achieved in that according to the method of removing liquid from a gas well, surfactants are held at the bottom of the reservoir on a ring mesh cuff installed pipes.
На чертеже представлена схема ре.а-лизацйи способа.The drawing shows the scheme of the re.A-licensed method.
Способ осуществл етс следуктщим образом.The method is carried out as follows.
Насосно-компрессорные труби 1 Pump Pipe 1
10 ( предварительно перфорируют, на них на уровне подошвы 2 продуктивного пласта 3 устанавливают сетчатую манжету 4. Затем насосно-компрессорные трубы спускают в скважину Бив зат15 рубнре пространство скважины забрасывают твердое пенообразуюцее 6 ПАВ, которое удерживаетс на манжете 4 и раствор етс .в поступающей из пласта жидкости.-Эта жидкость через отверс20 ти 7 барботируетс газом и в виде пены выноситс из скважины.10 (pre-perforated; a mesh cuff 4 is installed at the level of the sole 2 of the productive formation 3). Then the tubing is lowered into the well. reservoir of fluid. This fluid is bubbled through the hole 7 with gas and in the form of foam is carried out of the well.
Применение предлагаемого способа обеспечивает эффективное удаление жидкости с забо скважины при сокращении расхода ПАВ.The application of the proposed method provides effective removal of fluid from the bottom of the well while reducing the consumption of surfactants.
