Abstract

FIELD: oil production industry. SUBSTANCE: method allows for higher efficiency of well operation by deep-pumping procedure. According to method, reservoir product of various component setup comes from reservoir to well and rises through annular space formed by pump housing and production string, pump-compressor tubes and production string of well to required height where introduced into gas-liquid mixture is surface active substance of corresponding grade where mixture is degassed above gas-separator-demulsifier. Degassed liquid gas-liquid emulsion) flows through filters of gas-separator-demulsifier, overflows into pump-compressor tubes, and through annular space formed between pump-compressor tube string and hollow rod string it flows to inlet of immersed bottom-hole liquid pump, and further it flows through passage formed between housing and body of bottom-hole pump and reaches receiving chamber under high hydrostatic pressure of liquid column which presses underneath on pump plunger and when plunger moves upwards it relieves deep-pumping unit of part of load resulted from weight of liquid and rod string. In process of pumping out well product, gas is accumulated in annular space above steady-state dynamic level, which is sucked in and injected into pump-compressor tubes for mixing it with liquid discharging from hollow rods, thus sharply reducing density of gas-liquid mixture created in lifting tube string. Method allows for utilizing potential energy available in product itself for lifting of well product. Such energy is in difference of pressure of hydrostatic liquid columns in annular space and hole clearance; lifting energy of free gas emitting in annular space from oil for reducing oil density both in hole clearance and in pump-compressor tubes. Device has two pumps - lower pump of single-action with plunger pair and annular chamber, and upper pump of double-action with piston pair with side suction and delivery valves. Pumps are connected by string of hollow rods located concentrically in pump-compressor tube string having inlet and discharge openings. EFFECT: high efficiency.

Изобретение относится нефтедобывающей отрасли промышленности. Цель: повышение эффективности эксплуатации скважин штанговым глубиннонасосным способом. Продукция пласта с различным компонентным составом поступает из пласта в скважину и поднимается по межтрубному пространству образованному кожухом насоса и эксплуатационной колонной, насосно-компрессорными трубами и эксплуатационной колонной скважин до заданной высоты, где в газожидкостную смесь подает поверхностно-активное вещество марок"Превоцель" или др., которая над газосепаратором-деэмульгатором дегазируется. Далее дегазированная жидкость /газожидкостная эмульсия/ проходит через фильтры газосепаратора-деэмульсатора, переливается в насосно-компрессорные трубы, по кольцевому пространству образованному между колонной насосно-компрессорных труб и колонной полых штанг стекает к приему нижнего, жидкостного, глубинного насоса, далее проходит через канал, образованный между кожухом и корпусом глубинного насоса, поступает в приемную камеру под высоким давлением гидростатического столба жидкости, которая, подпирая снизу на плунжер насоса при подъеме плунжера вверх, снимает от глубиннонасосной установки часть нагрузки от веса жидкости и колонны штанг. В процессе откачки скважинной продукции в межтрубном пространстве скважины выше установившегося динамического уровня накапливается газ, который засасывают и закачивают в насосно-компрессорные трубы, перемешивая его с жидкостью, выходящей из полых штанг, резко снижая тем самым плотность образующейся газожидкостной смеси в подъемной колонне труб. Способ позволяет использовать для подъема скважинной продукции потенциальную энергию, имеющуюся в самой продукции и выражающуюся: в разности давлений гидростатических столбов жидкостей, находящихся в кольцевом и затрубном пространствах, подъемную энергию свободного газа, выделяющегося в межтрубном пространстве из нефти для снижения плотности нефти как в затрубном пространстве, так и в насосно-компрессорных трубах. Установка для осуществления способа добычи нефти содержит два насоса - нижний одинарного действия с плунжерной парой и кольцевой приемной камерой, верхний - двойного действия с поршневой парой с боковыми всасывающими и нагнетательными клапанами, насосы соединены колонной полых штанг, концентрично расположенных к колонне насосно-компрессорных труб соответственно с приемным и выкидным отверстиями. Установка позволяет уменьшить удельные электрозатраты, расходуемые на добычу скважинной жидкости.The invention relates to the oil industry. Objective: to increase the efficiency of well operation using a sucker rod method. Production of a formation with a different component composition enters from the formation into the well and rises through the annulus formed by the pump casing and production string, tubing and production casing of wells to a predetermined height, where “Prevocel” or other surfactants are supplied to the gas-liquid mixture ., which is degassed above the gas separator-demulsifier. Next, the degassed liquid / gas-liquid emulsion / passes through the filters of the gas separator-demulsifier, poured into the tubing, through the annular space formed between the tubing string and the hollow rod string flows to the bottom, liquid, deep pump, then passes through the channel, formed between the casing and the casing of the submersible pump, enters the receiving chamber under high pressure of the hydrostatic liquid column, which, supporting from below the pump plunger when lifting When the plunger is up, it removes part of the load from the weight of the liquid and the rod string from the deep pump installation. In the process of pumping downhole products in the annulus of the well above a steady-state dynamic level, gas accumulates, which is sucked in and pumped into the tubing, mixing it with the fluid leaving the hollow rods, thereby sharply reducing the density of the resulting gas-liquid mixture in the pipe lifting string. The method allows to use for lifting well products potential energy available in the product itself and expressed as: in the pressure difference of the hydrostatic columns of fluids located in the annular and annular spaces, the lifting energy of free gas released in the annulus from oil to reduce the density of oil as in the annulus and in tubing. Installation for implementing the method of oil production contains two pumps - the lower single-acting with a plunger pair and an annular receiving chamber, the upper - double-acting with a piston pair with side suction and discharge valves, the pumps are connected by a column of hollow rods concentrically located to the column of tubing, respectively with receiving and folding openings. The installation allows to reduce the specific electrical costs spent on producing well fluid.
