Abstract
The utility model relates to a self-vibrating oil increaser of an oil pumping well. The lower end of an upper joint (1) is connected to an upper perforated pipe (2) whose outer wall is provided with a negative pressure piston (3), and the lower surface of the upper perforated pipe (2) is connected with a middle joint (5), an excitation sheet (6), a lower perforated pipe (8) with a pipe plug (9), etc. in sequence. The utility model is characterized in that a negative pressure valve (4) is arranged in the upper perforated pipe (2), and a pulse valve (7) is arranged between the excitation sheet and the lower perforated pipe simultaneously. The utility model has the advantages of reasonable structure, convenient processing and reliable work, and can be broadly used for the measure of vibration oil increase in all kinds of oil pumping wells; because the utility model can prevent the diffusion of vibration pressure through an inner bore of an oil string, the utility model can markedly improve the unblocking effect of the vibration of positive pressure and negative pressure.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of pumpingh well self-vibration oil increasing device of oil well.
Technical background: before the utility model, each oil field is a periodicity axial vibration power of utilizing the upper and lower stroke tubing string of pumpingh well to produce, often adopt modes such as negative pressure piston and exciting sheet are installed on the pump lower tubular column, make the vibration wave of its generation positive and negative pressure and act on the stratum, to reach the purpose that de-plugging increases oil; But said apparatus is when work, because have the guide functions of tubing string endoporus, the upper and lower oil sets annular space of negative pressure piston and vibrating reed is connected state, the vibration pressure of its generation can be by the diffusion of tubing string endoporus, can not all do and be used for the stratum, greatly reduce the result of use of this device.
Summary of the invention: the purpose of this utility model: be to provide a kind of pumpingh well self-vibration oil increasing device for the oil field, this device not only is equipped with negative pressure piston and exciting sheet, in its tubing string, also cooperate simultaneously guillotine is installed, the vibration pressure that can prevent its generation is by the diffusion of tubing string endoporus, and all do and be used for the stratum, obviously improved the effect that de-plugging increases oil.
The purpose of this utility model realizes by following measure: a kind of pumpingh well self-vibration oil increasing device, comprise top connection, last floral tube, negative pressure piston, transition joint, exciting sheet, following floral tube and plug etc., and the top connection lower end connects the last floral tube that outer wall is equipped with the negative pressure piston, connect transition joint, exciting sheet and lower end below it successively and have following floral tube of plug etc., it is characterized in that being equipped with in the floral tube negative pressure valve of a sphere, the pulse valve of a disk shape is installed between exciting sheet and following floral tube simultaneously.
The utility model project organization is reasonable, easy to process, reliable operation, and the vibration that can be widely used in all kinds of pumpingh wells increases oily measure, and can obviously improve the plugging removal effect of negative pressure vibration.
Description of drawings: Fig. 1 is the structural representation of pumpingh well self-vibration oil increasing device.
Pumpingh well self-vibration oil increasing device is by top connection 1, go up floral tube 2, negative pressure piston 3, negative pressure valve 4, transition joint 5, exciting sheet 6, pulse valve 7, floral tube 8 and plug 9 etc. constitute down.Top connection 1 lower end connects the last floral tube 2 that outer wall is equipped with negative pressure piston 3, connects the pulse valve 7 of transition joint 5, exciting sheet 6, disk shape and the following floral tube 8 that the lower end has plug 9 below it successively, in the last floral tube 2 the negative pressure valve 4 that also has a sphere is installed.
The specific embodiment: can pumpingh well self-vibration oil increasing device be connected to pumping pipe string pump lower end by top connection 1 during use, and with the pumping pipe string G.I.H, down-hole liquid stream can enter deep well pump by descending floral tube 8, pulse valve 7, negative pressure valve 3 and last floral tube 2 etc., makes it finish normal oil pumping work; When sucker rod is up, tubing string can produce elastic shrinkage, and move on drive negative pressure piston 3 and the exciting sheet 6 etc. negative pressure vibrating effect of its lower room generation, also simultaneously close owing to negative pressure valve 4 this moment, prevented vibration pressure by the diffusion of tubing string endoporus, and then strengthened negative pressure vibrating effect layer; When sucker rod is descending, tubing string can produce elastic elongation, and drive negative pressure piston 3 and exciting sheet 6 etc. move down malleation vibrating effect of its lower room generation, close owing to pulse valve 7 also can take place by moment simultaneously this moment, prevented that vibration pressure is by the diffusion of tubing string endoporus, and then strengthened malleation vibrating effect, thereby reached the purpose that improves the vibration oil increasing effect to the stratum; In the pumpingh well self-vibration oil increasing device course of work, close, thereby can not influence normal the inflow in the deep well pump of down-hole liquid stream because 7 of pulse valves take place by moment.
