Abstract
The utility model relates to a novel solid anticorrosion device, relating to the anticorrosion technology. The structural relation of the novel solid anticorrosion device is that an oil tube is internally provided with an oil-well pump, and a sieve tube is installed under the oil-well pump. Two long anticorrosion devices and two short anticorrosion devices are arranged on a solid anticorrosion device, and the sieve tube is connected with one end of one long anticorrosion device by a screw thread. The two long anticorrosion devices and the two short anticorrosion devices are connected by screw threads, and one end of one short anticorrosion device is connected with a screwed plug through a screw thread. A nanometer carrier, an LD organic efficient solid inhibitor, a sacrificial anode, a releaser and a solution speed regulator are arranged in each anticorrosion device, wherein the sacrificial anode is made of specially made alloy which easily loses electrons and can keep certain release time. The utility model is convenient to use, has low cost, wide application range and no pollution, is a feasible anticorrosion technology, can protect the oil tube, a sleeve, underground equipment, gathering lines, water injection lines and equipment, and can protect the stratum and the environment against damage.
Description
One, technical field: the utility model relates to a kind of anticorrosion utensil, especially a kind of novel solid corrosion-resisting device.
Two, background technology: at present, Oilfield using be to the oil sets annular space heavy dose add inhibiter, press down the salt agent, scale inhibitor and to measures such as near wellbore formation squeeze note high density agent, this also is a most frequently used method at present.But have a lot of shortcomings in actual use: cost is higher, workload is big; It is short that effect is not steadily, difficulty is controlled validity period; Dosing was invalid when higher or production fluid amount was big at the oil well oil gas ratio.
Three, summary of the invention: the purpose of this utility model provides a kind of novel solid corrosion-resisting device easy to use; it has adopted unique solid corrosion technology and cathode protection technology; realized the purpose that erosion rate can steadily be controlled; greatly prolong the validity period that oil and water well is used, had certain wax removal effect simultaneously.The novel purpose of this use is achieved in that it is to be formed by connecting by oil pipe, oil well pump, screen casing, solid corrosion-preventing device and plug, and oil well pump is arranged in oil pipe, screen casing is installed below the oil well pump; Two long corrosion-preventing devices and two short corrosion-preventing devices are arranged on the solid corrosion-preventing device, one end of a screen casing and a long corrosion-preventing device is by screwed connection, between two long corrosion-preventing devices and two the short corrosion-preventing devices respectively by screwed connection, one end of a short corrosion-preventing device and plug be by screwed connection, nano-carrier, LD efficient organic solid corrosion inhibitor is installed respectively in each corrosion-preventing device, easily loses electronics and can keep the special alloy of certain time of releasing to do sacrificial anode, reliever, dissolution rate regulator.
The utility model is easy to use, cost is lower, applied widely, be a practicable aseptic technic; It not only can play the effect of protection oil pipe, sleeve pipe and underground equipment, and can play the effect of protection gathering line and waterflood-transmission line, equipment; It is pollution-free, can protect stratum and environment not to suffer damage.
Four, description of drawings: Fig. 1 is a kind of scheme of installation of novel solid corrosion-resisting device, among the figure 1, oil pipe 2, oil well pump 3, screen casing 4, solid corrosion-preventing device 5, plug
Fig. 2 is the structural representation of solid corrosion-resisting device, among the figure 3, screen casing 5, plug 6, long corrosion-preventing device 7, short corrosion-preventing device
Five, embodiment: in Fig. 1 and Fig. 2, oil well pump 2 is arranged in oil pipe 1, screen casing 3 is installed below the oil well pump 2; Two long corrosion-preventing devices 6 and two short corrosion-preventing devices 7 are arranged on solid corrosion-preventing device 4, one end of a screen casing 3 and a long corrosion-preventing device 4 is by screwed connection, respectively by screwed connection, an end of a short corrosion-preventing device 7 and plug 5 are by screwed connection between two long corrosion-preventing devices 6 and two the short corrosion-preventing devices 7; Nano-carrier, LD efficient organic solid corrosion inhibitor are installed respectively in each corrosion-preventing device, easily lose electronics and can keep the special alloy of certain time of releasing to do sacrificial anode, reliever, dissolution rate regulator.
