Description
Technical field
The utility model relates to the oil recovery technique field, particularly a kind of sleeve pipe automatic medicine adding apparatus that paraffin removing with chemical method is used in the oil recovery process of oil field.
Background technology
At the oil field oil recovery process, bring fouling in the corrosion of down-hole string and gathering line and the pipeline because of height is moisture, bring oil well production wellhead back pressure height, this just needs to add chemical agent toward interior input of oil well, the purpose that reaches inhibition, wax control, viscosity reduction and prolong duty cycle.Adopt artificial dosing and special-purpose vehicle dosing to carry out dosing at present.There is more drawback in artificial well head dosing method: the first amount of labour is big, dosing complex procedures, particularly distance, road conditions are poor, runs into sleety weather, and the dosing difficulty is bigger.It two is that dosing is discontinuous, adds every day or several days slug formula dosing once, can not allow medicament evenly play a role continuously.It three is that to add the water yield few, and medicament is dissolved dilution fully, can not guarantee the dosing effect, has increased cost of production.
The utility model content
The purpose of this utility model is: a kind of cluster well place face automatic medicine adding apparatus is provided, can stores medicine and can utilize casing pressure, realize Automatic Dosing in the oil jacket annular space, reduce production costs and working strength of workers.
The technical solution adopted in the utility model is: cluster well field sleeve pipe automatic medicine adding apparatus, mainly form by fluid level control device, dosing funnel, medicine storing pot, control pipeline, electrically-controlled valve, hand-operated valve and base.It is characterized in that: on base, be fixed with medicine storing pot.Medicine storing pot is the enclosed shape jar, is fixed with fluid level control device at the top of medicine storing pot, is connected with chemical feed pipe at the top of medicine storing pot, is connected with valve and dosing funnel on the chemical feed pipe.Can in medicine storing pot, add aqueous chemical processing medicament by the dosing funnel, can control the height of medicine storing pot inner liquid medicine by fluid level control device.Be welded with the control pipeline on medicine storing pot top, more than the liquid level of an end opening in medicine storing pot of control pipeline.The other end of control pipeline is in the medicine storing pot outside, the other end of control pipeline is connected on the discharging tube of medicine storing pot, can be delivered to the pressure of annular space in the oil well casing in the medicine storing pot by the control pipeline like this, make pressure and the interior annular pressure of oil well casing in the medicine storing pot keep balance.Bottom at medicine storing pot is welded with discharging tube.Be connected with hand-operated valve and electrically-controlled valve on the discharging tube.Discharging tube can be communicated with annular space in the oil well casing.
The other end of described control pipeline is to be connected on the discharging tube of medicine storing pot on the discharging tube between the hand-operated valve and electrically-controlled valve.
Be connected with two hand-operated valves and an electrically-controlled valve on the described discharging tube.Electrically-controlled valve is in two hand-operated valve centre positions.
Utilize oil well casing annular pressure and medicine storing pot pressure balance, the chemical treatment medicament in the medicine storing pot flows in the sleeve pipe automatically by the liquid difference of soup, is embodied as the purpose of oil well dosing.This device need not any power assist apparatus, only needs its discharging tube is connected on the well head, configures 0～30 day dosing cycle according to hole condition then, adds 0～200 liter/time of dose, controls electrically-controlled valve automatically by automatic control system and carries out dosing in the oil well.
The dosing flow process is: by manually adding enough soups from the dosing funnel to medicine storing pot, then by manually opening valve on the control pipeline, allow automatic control system be in the dosing SBR, automatic control system will regularly be opened electrically-controlled valve according to the dosing cycle that configures and carry out dosing, according to adding dose and liquid level, close electrically-controlled valve in good time, finish a dosing cycle.
The beneficial effects of the utility model: the utility model cluster well field sleeve pipe automatic medicine adding apparatus, can utilize the pressure in the oil well casing annular space, realize Automatic Dosing in the oil well casing annular space, can reduce working strength of workers.Have advantages such as unmanned operation automatically, few easy workout part, maintenance cost be low.
