Definitions

  • the present invention relates to the oil and gas industry, and more specifically to the structural elements of a sucker rod pumping unit (SHGU), which can be used, in particular, for oil production.
  • SHGU sucker rod pumping unit
  • SHGNU and electric centrifugal pumping units operate relatively effectively at depths up to 2000-2200 meters. But with an increase in the immersion depth of the rod pump, the weight of the rods also increases, and the diameter of the plunger decreases. Already at depths of 2000-2200 meters, the weight of the rods reaches 80%, and the payload is only about 20%. In addition, the stroke of the plunger is significantly reduced relative to the course of the polished rod, which significantly reduces the flow rate and efficiency of the SHNU.
  • the weight of the rods is reduced by using high-strength steels from which the rods are made, but this reserve has already been exhausted.
  • one of the most important nodes of the ShGNU is a deep-well sucker-rod pump with a pump plunger stroke length of 15 meters or more, the manufacture of which is associated with the need for sectioning - connecting individual sections directly to the well. This work, given the large length of the movement of the pump plunger and the depth of the well, requires high centering accuracy of adjacent sections.
  • Both of the proposed invention are aimed at creating such a design of a sectional sucker rod pump unit, which allowed to increase the productivity and depth of extraction of pumping and reduce its cost.
  • the closest to the proposed hollow rod in terms of number of essential features is a hollow rod of a sucker rod pump installation containing a cylindrical body and heads mounted at the ends of a cylindrical body / V. Muravyov. Oil and gas well operation. - M .: Nedra - 1973. - S. 210 - 230 /.

USSR N ° 1193292, IPC 4 F04B 47/00, publ. 11/23/1985 Bull. Ne 43 /. Sections of the described cylinder are located in the casings.
  • Cylinder sections are mounted directly on the well, while certain violations of the centering of the sections are possible, which are compensated by the conical shapes of the hollow plunger and the end sections of the sections. Moreover, during the movement of the plunger, the mentioned conical surfaces interact with each other and center adjacent sections, but during the movement of the plunger through the junction of the sections, both he and the sections undergo increased wear. In addition, the presence of a casing and additional elements significantly complicates the design of the sucker rod pump, which reduces its reliability and increases the price.
  • the basis of the proposed inventions is the task of creating such a hollow rod and a sectional borehole long-stroke rod pump, which would be more reliable by creating conditions to reduce the load on the drive and the rod. The problem is solved by the use of the proposed rod in the SHGNU design, which allows creating conditions for reducing the rod weight force by using the buoyancy force of the fluid that the well is filled with on the rod.
  • the proposed, as well as the well-known hollow rod of a sucker rod pump installation includes a tubular body and heads mounted on the ends of the tubular body, and, in accordance with the proposal, each head is made solid and hermetically fixed to the corresponding end of the tubular body.
  • the proposed, as well as the well-known sectional long-stroke sucker-rod pump contains a cylinder made in the form of series-connected sections and has a hollow plunger installed in the cylinder with a discharge valve, as well as a suction valve, and, in accordance with the proposal, adjacent sections are interconnected with by means of a bolt flange connection containing at least two centralizer pins located in through-through coaxial holes made around the circumference of adjacent flanges, and each centralizer pin is made oval in the form of a rod having a central conical and extreme threaded sections.
  • a feature of the proposed sectional borehole long-stroke sucker-rod pump is that the axes of the through coaxial holes in adjacent flanges in which the centralizer pins are installed are asymmetric with respect to the connection axis of adjacent sections.
  • a flange is a connecting part of cylindrical sections (pipes), having the form of a flat ring or disk with holes for bolts evenly spaced around the circumference, designed to connect the flanges of adjacent sections (pipes) to each other along the outer planes of the respective flanges.

  • Adjacent sections 8 are connected by respective flanges 13 and 14.
  • Through flanges 13 and 14 have through holes for bolts with an internal hexagonal blind hole in the head / not shown / to reduce the dimensions of the flanges.

  • the vertical axes of the two through holes 15 in which the centralizer pins are mounted are asymmetric with respect to the axis of the connected sections 8, which ensures the optimal centering of adjacent sections 8 during installation of the cylinder in the well due to the possibility of displacement of the flanges 13 and 14 to align the axes of the adjacent sections 8

Then, the connected and marked sections 8 forming the cylinder are disassembled and transported to the well, where installation is carried out taking into account the marking.
  • each rod contains a tubular housing 1 with a cavity 2 sealed with heads, filled with air, the force of its weight is directed downward and the Archimedean force is directed upward, and therefore the weight of the proposed rod in the fluid is substantially decreases, which contributes to an increase in the immersion depth of the rod pump or its diameter without increasing the load on the drive SHGNU.
  • a column of the proposed float rods in a liquid reduces weight, but not mass - inertial acceleration is more intense than in solid and tubular rods, which increases the stroke of the plunger / not shown / compared to the course of the polished rod, and not decrease, as it usually on continuous and tubular rod columns.
  • a column of hollow rod-floats can significantly increase the diameter of the pump or the immersion depth of the pump without increasing the load on the SHGNU drive.

Abstract

La présente invention relève du domaine de l'industrie du pétrole et du gaz. La tige creuse d'une colonne de tiges pour installation de pompage en profondeur à tiges comprend un corps tubulaire et des têtes. Chaque tête est compacte et hermétiquement fixée à l'extrémité du corps tubulaire de la tige. Une pompe à tiges à course allongée pour puits profond compartimentée comporte un cylindre se présentant sous la forme de compartiments connectés en série (8) et comprend un piston jumelé (9, 10) placé dans le cylindre et pourvu de soupapes de pompage (11, 12) et de soupapes d'aspiration. Les compartiments adjacents sont reliés à l'aide d'un raccord à brides boulonné (13, 14) comprenant au moins deux tiges de centrage disposées dans des trous traversants coaxiaux prévus sur la circonférence de brides adjacentes (13, 14). Chaque tige de centrage se présente sous la forme d'une barre pourvue de parties coniques centrales et de parties filetées d'extrémité. Les axes des trous traversants coaxiaux dans des brides adjacentes pourvues de tiges de centrage sont des axes asymétriques par rapport à l'axe de raccordement des compartiments adjacents. Cette invention permet d'accroître la fiabilité en réduisant la charge appliquée sur une commande et des tiges au moment d'une commande inversée et de réduire l'usure du piston et des zones reliant les compartiments adjacents.
