Abstract
The utility model relates to a steam overpump heating oil production steam distributor for the steam viscous crude extracting art, which consists of a steam distributing tube 1, universal steam distributing connectors 2, 4, 6, and 8, a fixing link rod 3, active link rods 5 and 7, a hollow slick rod 9, a heat insulated hollow oil extracting rod 10, a sliding slick rod 11, a dividing tube 12. the device is convenient for assembling and maintenance and can work reliably, while the energy consuming and cost are low and also can heat the viscous crude using the energy provided by the steam entirely, and can extract while injecting to improve the productivity efficiency of the oil extracting of the viscous crude, thus is suitable for popularizing.
Description
The utility model relates to a kind of steam-matching device that is used for steam injection thickened oil recovery technology.
At present, thickened oil recovery is adopted usually and is mixed processes such as thin oil, dosing viscosity reduction, electrical heating, steam injection, and wherein two kinds of application later on are more, and effect is better.Because the electrical heating production practice need dispose appliance arrangements such as transformer, power distribution cabinet, cable, and the cable transmission distance, reactive loss and power consumption are big, and its production cost is increased.By comparison, exploitation via steam injection technology then has certain advantage, range of application, larger on energy consumption and production cost.Yet the on-the-spot at present heat extraction by steam injection technology that is adopted is mainly taked steam flooding and steam soak dual mode, and the former needs ad hoc notes vapour well, by annotating the vapour well steam is injected the oil reservoir heating and drives viscous crude to the producing well extraction; Though the latter needn't ad hoc notes vapour well, to adopt dual-purposely and annotate by producing well, this well " is handled up ", needs the stewing well a few days of closing well after injecting steam, thereby rate reduces when well recovery is produced, and influences heavy oil production and exploitation effect.
The purpose of this utility model is to provide a kind of efficient heating, marginal not limit of can realizing to adopt, do not need closing well to boil in a covered pot over a slow fire well, thereby the steam of rate and heavy oil production is got over pump heating oil recovery steam-matching device can improve well recovery and produce the time.
The utility model is to realize like this.This kind steam-matching device is by steam distributing pipe, fixing link rod, the universal vapour joint of joining, movable link rod, hollow polished rod, heat insulation hollow rod, the slip polished rod, isocon is formed, its structure, assemble as follows: steam distributing pipe steam input be connected from the steam injection pipeline of injection boiler with the steam transmitting pipe net, output is connected with the universal vapour joint of joining that is positioned at oil pumper walking beam bearing upper end side, this is joined vapour joint opposite side and links to each other with the parallel fixedly link rod of walking beam, fixedly the link rod front end is connected with the universal vapour joint of joining that is positioned at the pumping unit horsehead side, this is joined vapour joint below and is connected with two movable link rods and two universal vapour joints of joining successively at interval, and its lower end then is connected with the hollow polished rod of pumpingh well well head top; Hollow polished rod is connected with the hollow heat insulated sucker rod of G.I.H, and the rod string lower end is connected to the slip polished rod, and by the joint tipping isocon is arranged.The above-mentioned connection of whole device is and is threaded.When pumpingh well is produced, restart oil pumper after annotating the vapour preheating, steam along steam distributing pipe, universally join vapour joint, hollow fixedly link rod and movable link rod and hollow polished rod, hollow rod, slip polished rod and isocon inject oil reservoir downwards, viscous crude then upwards flows to well head along the annular space between oil pipe and the hollow rod from the down-hole.In this process, steam and viscous crude carry out countercurrent flow, and heat energy accumulates near the well head, and progressively to the down-hole deeply, the viscous crude behind the assurance heating viscosity reduction is by the smooth extraction of oil well pump.The oil of output does not need post bake, can directly enter high racking oil tank or enter the defeated block station of collection, multi-purpose station under the situation of saving well head heater or water jacket furnace.
The utility model is simple in structure, assembles easy to maintenancely, safe and reliable, and energy consumption and production cost are lower, can make full use of to inject the heat energy that steam provides, and efficiently heats viscous crude, realizes that the marginal not limit adopts, and improves the heavy oil wells rate when producing of recovering the oil, and is suitable for and applies.
General structure schematic diagram when Fig. 1 is work of the present utility model.Among the figure, label " 14 " is an oil pumper, and label " 15 " is steam injection pipeline and respective valves, instrument, and label " 16 " is a wellhead for production, and label " 17 ", " 18 " are respectively oil well casing and oil pipe, and " 19 " are hollow oil well pump.
Fig. 2, Fig. 3 are this device down-hole isocon part-structure schematic diagram and profile.
Fig. 4 is the universal vapour joint design schematic diagram of joining.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
As shown in the figure, the utility model by steam distributing pipe 1, universally join vapour joint 2,4,6,8, fixedly link rod 3, movable link rod 5,7, hollow polished rod 9, heat insulation hollow rod 10, slip polished rod 11, isocon 12 are formed.Wherein, universal vapour joint 2,4,6,8 (see figure 4)s of joining are by plug 20,21, main body 22, fixedly Intaking joint 23, metal porcelain pad 24, gland 25, soket head cap screw 26, filler gland 27, sealing ring 28, universal turning joint 29 and clamp nut 30 are formed, main body 22 tops one side is respectively equipped with fixedly Intaking joint 23 and the interface that is connected with movable link rod with the middle part opposite side, and arranged outside has the universal turning joint 29 that can do gyration.Isocon 12 (seeing Fig. 2, Fig. 3) pipe that to be an inside and outside footpath match with the hollow rod joint, along being drilled with (4-8 every group of many groups on the total length tube wall, Figure 5 shows that 8) circular hole that is uniformly distributed along the circumference, its upper and lower end is welded with upper and lower joint respectively, wherein internal thread is with in the top connection upper end, and the lower contact bottom is the conical surface.Fixedly link rod 3, movable link rod 5,7 are hollow round bar.Inject for reducing the steam heat loss, improve steam heat efficient, steam distributing pipe 1, fixedly link rod 3, movable link rod 5,7 and hollow heat insulated sucker rod 10, slip polished rod 11 surfaces are equipped with the heat insulating coat of thick about 2mm.Slip polished rod 11 can adopt hollow polished rod.
