Abstract
A full-automatic adjustable oil well underground continuous agent adding device is a device applied to oilfield production and used for the oil well paraffin prevention function, the corrosion prevention function and the scale prevention function. The full-automatic adjustable oil well underground continuous agent adding device unceasingly squeezes out agents with the help of pulses in the normal production process, and therefore continuous agent adding is achieved, and no external power supply or power supply is needed. The full-automatic adjustable oil well underground continuous agent adding device overcomes the defects that in an existing agent adding device, the effect of the agents gradually weakens and the corrosion and paraffin prevention performance is gradually degraded, the repair-free period of an oil well is greatly prolonged, oil well repairing cost is reduced, and the sustained yield of the oil well is improved. At present, the full-automatic adjustable oil well underground continuous agent adding device has been applied to the oil well, and the full-automatic adjustable oil well underground continuous agent adding device is remarkable in economic effect and practical effect.
Description
Technical field
The present invention is a technology for the anticorrosion of oilfield manufacturing process, wax control and good antiscale property field.Oil well etching problem is the common problem that all oil fields all must face in oil well production, oil well corrosion can cause greatly reduce the application life of the equipment such as oil pipe, sucker rod and pump, much several hundred million yuan of the direct economic loss that oil pipe, sucker rod and the pump of scrapping because of corrosion every year causes; And the indirect economic loss that oil well stoppings production, maintenance activity etc. that cause because of corrosion cause is difficult to calculating especially.Oil well paraffinication is ubiquitous another problem in oil well production process, oil well paraffinication meeting causes oil well to stop production, the average wax period of the fireballing oil well of wax deposition is 40 days, wax removal means adopt the method that clear water heat cycles is cleaned at present, but there is the problem of external liquid contamination oil reservoir in the method, if do not carried out hot water well-flushing, solve stopping production problem, adopted flowline and beam hanger wax removal, this can cause the increase of stopping production and construction cost equally.
For oil well corrosion and these two problems of wax deposition, the solution of oil field routine is to add anticorrosive and wax-proofing agent at sleeve pipe, this operation need to manually be injected anticorrosion and wax control medicament from annular space, this conventional dosing technology belongs to impact type dosing, when drug concentration is higher, play a role, but along with the consumption of medicament is anticorrosion and wax control effect dies down, can not reach the effect of continuous action.
Background technology
This invention configures required anticorrosion, wax control medicament according to the experimental result of produced liquid in oil well, the wax control anti-corrosion agent configuring is packed in the medicine storage device under pump, by this automatic medicine adding apparatus, together with deep well pump in lower going-into-well, when deep well pump is started working, this chemicals dosing plant starts working.In the oil pump course of work, oil pipe can output be wriggled, under the frequency that down-hole auto continuous chemicals adding apparatus under this invention is wriggled at oil pipe by the wriggling of oil pipe, quantitatively discharge required medicament, thereby realize, continue dosing, keep the stable anticorrosion wax control performance of medicament in well, and each pharmaceutical quantities of discharging can be set in advance according to oil well concrete condition.
Large 45 blocks of Jilin Oil Field are positioned at the south in large peace oil field, and stratum, this area Produced Liquid salinity is high, corrosivity is serious.Statistics shows, the annual oil well corrosion condition in this area accounts for 50% of all well numbers of this oil field block, the seriously corroded of pipe, bar and pump, and oil well repair free period is short.
Large 45-8-20 well was gone into operation over 6 years, and average oil well repair free period is 210 days, adopts conventional sleeve pipe to add medicament to carry out after anticorrosion wax control improvement, and the phase of being excused from a college course is extended down to 280 days, but dosing process complexity is not easy to operation.After the auto continuous chemicals adding apparatus that 2012 apply under this invention, the phase of being excused from a college course rises to 380 days.
Summary of the invention
This technology has two inventive points:
1) can realize at down-hole continuous dosing.Thereby solve conventional dosing method Chinese medicine concentration and after dosing, reduce gradually the situation anticorrosion and that wax control performance reduces gradually that causes;
2) need not be additional or supply any power.Do not need to be equipped with battery or other power supplies.
Claims (2)
1. Full-automatic adjustable oil well device for continuously adding medicine is the equipment being applied in field produces for oil well paraffin prevention, anticorrosion and anti-scaling function, it is by constantly extruding medicament by the pulse of oil well normal productive process, realize continuous dosing, need not any additional power source or power supply.
2. the present invention is characterized as 1) down-hole continuous dosing, 2) need not additional power source or power
The technical products of this invention is by 1) sliding sleeve lid, 2) sliding sleeve, 3) holding screw, 4) spring, 5) wiper block, 6) nut, 7) central tube, 8) become silk and 9) shake hammer totally nine parts formations.
