Abstract
The present invention relates to a sand-cleaning pump-sink one-step pipe string technique and pump-passing sand-cleaning and sand-filtering equipment. The technological process for implementing said one-step ppie string technique for cleaning sand and filtering sand includes the following steps: firstly, using original well pipe to detect sand surface, then sinking pump air and rod to clean sand and pumping out the sand obtained by cleaning well bottom so as to implement well completion. The pump-passing sand-cleaning equipment for implementing said technological process is formed from upper joint, outer working cylinder, sealing slide block, reset spring, check valve, sieve pipe, plug, lower joint, sand-cleaning hole and piston sinking cylinder, etc.
Description
Relate to the field:
The present invention relates to oil field sand well pump detection and workover technology, especially: sand washing, time string technology of pump and the sand washing of mistake pump, sand filter.
Prior art:
In the work of oil field sand well pump detection and workover, the operation of pump detection and workover is at present: visit the sand face with former well casing post earlier, trip out former well casing, roofbolt then; Following sand washing tubing string carries out sand washing, and sand washing is left standstill the sand face of visiting that returned in four hours to the artificial bottom of a well; If no sand then plays the sand washing tubing string; Descend at last pump line and sucker rod to hang and exhaust well; This pump detection and workover operation process is more loaded down with trivial details, and labor strength is big, expends man-hour, has increased the oil producing operation cost.
Summary of the invention:
In order to address the above problem, sand washing of the present invention, string technology of pump and the purpose of crossing pump sand washing, sand filter are down: reduce down sand clean out pipe and play a sand clean out pipe twice work operation, reduce labor strength, shorten man-hour; To achieve these goals, sand washing, down the operation process of a string technology of pump is: visit the sand face with former well casing post earlier, trip out former well casing, bar, then new pump line and sucker rod down; Descend oil pick-up tube to carry out sand washing again, after sand washing does not have sand to the shaft bottom, trip out again to hang behind the unnecessary oil pipe and exhaust well; And realize this purpose cross pump sand washing, sand filter by: top connection, outer working tube, sealing slide block, back-moving spring, ball-and-seat, screen casing, plug, lower contact, scouring sluice, the heavy tube of piston are formed; Cross pump sand washing, sand filter when carrying out above-mentioned working programme: move downward under the effect of oil well pump piston at gravity, after being connected the top connection under the pump barrel, piston promotes sealing slide block compression reseting spring, scouring sluice is slowly opened this moment, the sand cleaning fluid of oil pipe inside enters annular space between the heavy tube of outer working tube and piston by scouring sluice, enter tail pipe by lower contact at last, thereby realize the work of sand washing; Carry on the piston enter pump barrel after because the effect of back-moving spring, the sealing slide block moves upward, and seals scouring sluice, thereby realizes the function of oil well pump; Screen casing is arranged below ball-and-seat, be used for realizing the effect of filter sand; Sand washing of the present invention, time string technology of pump and the sand washing of mistake pump, sand filter, be put under the piston by oil well pump back-moving spring arranged under the pump barrel of no standing valve cross pump sand washing, sand filter, after exposing scouring sluice, realize that sand cleaning fluid walks around the piston of ball-and-seat and pump by scouring sluice, enter tail pipe by annular space again, thereby realize the purpose of sand washing; This process has been saved traditional following sand clean out pipe and the flow chart that plays sand clean out pipe, can carry out the sand washing operation at any time and need not trip out former pump and hang; Reduce the activity duration, alleviated working strength of workers, reduced labour cost.
Description of drawings:
Accompanying drawing is sand washing, following string technology of pump and the work schematic diagram of crossing pump sand washing, sand filter.
The specific embodiment: following (as shown in the figure) with reference to the accompanying drawings is to the present invention: sand washing, string technology of following pump and pump sand washing excessively, sand filter is described further: cross the pump sand washing machine and be by top connection 1, outer working tube 2, sealing slide block 3, back-moving spring 4, ball-and-seat 5, screen casing 6, plug 7, lower contact 8, scouring sluice 9, the heavy tube 10 of piston is formed: cross the pump sand washing, sand filter is when carrying out above-mentioned working programme: move downward under the effect of oil well pump piston at gravity, after being connected the top connection 1 under the pump barrel, piston promotes sealing slide block 3 compression reseting springs 4, scouring sluice is slowly opened for 9 this moments, the sand cleaning fluid of oil pipe inside enters annular space between the heavy tube 10 of outer working tube 2 and piston by scouring sluice 9, enter tail pipe by lower contact 8 at last, thereby realize the work of sand washing; Carry on the piston enter pump barrel after because the effect of back-moving spring 4, sealing slide block 3 moves upward, and seals scouring sluice 9, thereby realizes the function of oil well pump; Screen casing is arranged below ball-and-seat, be used for realizing the effect of filter sand; Sand washing of the present invention, time string technology of pump and the sand washing of mistake pump, sand filter, be that piston by oil well pump is placed down in the crossing in pump sand washing, the sand filter of back-moving spring 4 arranged under the pump barrel of no standing valve, expose scouring sluice 9 and realized afterwards that sand cleaning fluid passed through scouring sluice 9, walk around the piston of ball-and-seat 5 and pump, enter tail pipe by annular space again, thereby realize the purpose of sand washing; Realized visiting the sand face with former well casing post, following pump line and bar carry out sand washing, hang the operation process that exhausts well at last, have saved traditional following sand clean out pipe and the twice operation procedure that plays sand clean out pipe.
Claims (2)
