Abstract
The utility model relates to a matching production device for oil and gas wells, particularly to a dropping chemical adding device for oil and gas wells. The utility model is composed of a chemical containing tank and a chemical adding opening. The dropping chemical adding device is characterized in that a short pipe head, a dropping valve, a chemical dropping nozzle, a short connector and a joint are arranged on the lower end of the chemical containing tank, wherein a chemical dropping hole is arranged in the lower end of the chemical dropping nozzle, an observation window is arranged on the short connector, a diversion pipe is arranged in the joint, and the lower part of the joint is connected with a connecting pipe; the upper end of a communicating pipe is connected with the top of the chemical containing tank, and the lower end is connected to the connecting pipe; a communicating valve is arranged on the communicating pipe. The dropping chemical adding device has the advantages that chemicals can be evenly added into wells whether pressure exists in annular space of an oil jacket of an oil well or not; a power device does not need to be additionally arranged, the installation cost can be saved, and energy can be saved; the utility model has simple structure, convenient operation, no moving parts and reliable work; failures generally can not occur. The utility model is suitable for adding chemicals into well openings of the oil and gas wells.
Description
Technical field
The utility model relates to a kind of production corollary apparatus of oil gas well.
Background technology
In oil gas well oil recovery process, in order to increase crude output, the soup of need in well wellbore, annotating equably.Its adding method thereof commonly used has direct annotation method and infusion method.When oil well does not have casing pressure, can adopt direct annotation method, this method is that every day is regularly by a certain amount of soup of manually annotating in the oil jacket annular space, the soup of regularly annotating 2-3 time every day, the soup that adds is very inhomogeneous, fashionable pit shaft herb liquid is many just adding, and concentration is big, and the time is long more, liquor strength in the pit shaft is just more little, the dosing effect is very bad, can not play the effect of incremental oil production, also wastes soup.When oil well has casing pressure, adopt dosing in the infusion normal direction oil well, this method is at well mouth of oil well the device that one cover comprises plunger displacement pump, contains medicinal cupping, connecting line etc., the soup though this covering device can be annotated in pit shaft more equably to be installed, but cost is than higher, need power again, install and use all cumbersome, and since pressure bigger, annotating the plug pump also often breaks down, need the termination of pumping maintenance, so both influenced dosing, increased cost of crude oil production again.
The utility model content
The purpose of this utility model provides a kind of evenly dosing in well, cost oil gas well point low, easy to use drips medicine device.
Technical solution of the present utility model is to realize like this, a kind of oil gas well point drips medicine device, constitute by containing medicinal cupping and being installed in the dosing mouth of containing on the medicinal cupping, its special character is that (1) is equipped with nipple in the lower end of containing medicinal cupping, and nipple is equipped with a drip trap, drug-dripping port, short circuit and joint successively, lower end at drug-dripping port has drug dropping hole, have observation port on short circuit, mozzle is housed in joint, joint lower end and junction pipe link together.(2) top of communicating pipe upper end and Sheng medicinal cupping connects mutually, and communicating valve was housed on communicating pipe, communicating pipe the lower end and junction pipe link together.(3) on containing medicinal cupping, outlet valve is installed.
Usefulness of the present utility model is, (1) because by the oil jacket annular space of containing medicinal cupping and oil well is interconnected, make wellbore pressure and contain the interior pressure balance of medicinal cupping, can realize dripping automatically the purpose of medicine, no matter in the oil sets annular space of oil well whether pressure is arranged, can dosing in oil well equably.(2) this device does not need to install additional power set, both can save installation cost, can conserve energy yet.(3) this apparatus structure is simple, only need control several valves during use, and is easy to operate, and movement-less part is reliable, generally can not break down.
Description of drawings
Accompanying drawing is a cross-sectional view of the present utility model.
The specific embodiment
Contain medicinal cupping 6 with welded steel plate, the nipple 11 that has screw thread in the bottom welding of containing medicinal cupping, nipple 11 is by screw thread or flange mounting points drip trap 13, drug-dripping port 3, short circuit 2 and joint 1 successively, point drip trap 13 is selected needle valve for use, has the drug dropping hole of diameter 3-5 millimeter at the middle part, lower end of drug-dripping port 3.If this device that uses on stress-free oil well, short circuit 2 can be made of material transparent, so that this device passes through the speed under this short circuit observation medicine liquid droplet when operation.If this device that uses on the oil well that big pressure is arranged, this short circuit 2 can use steel pipe manufacturing, and thicker withstand voltage transparent material of installation on steel pipe as observation port, can be observed situation under the medicine liquid droplet by this observation port.Be connected with catheter 17 upper ends in joint 1, joint 1 lower end and junction pipe 16 weld together.Communicating pipe 10 and contain medicinal cupping 6 tops and be bound up, communicating pipes 10 lower end be connected with junction pipe 16, communicating pipes 10 middle part communicating valve 12 is housed.At the top of containing medicinal cupping 6 dosing mouth 8, pressure meter 9 and outlet valve 7 are installed also, the convertible content gauge 5 of magnetic are installed, blowoff valve 4 is installed in the bottom of containing medicinal cupping 6 in the side of containing medicinal cupping 6.
During installation, junction pipe 16 is installed on the well head by flange, makes junction pipe 16 by being connected in ring set clip (flange) and the oil well, and makes the oil sets annular space of the outlet of mozzle 17 over against oil well, be i.e. annular space between oil pipe 14 and the sleeve pipe 15.Install the valve that a certain amount of soup is closed outlet valve 7 and dosing mouth 8 additional with containing in the medicinal cupping 6, communicating valve 12 is opened, make and contain in the medicinal cupping 6 and the pressure balance in the oil well ring set space, open a drip trap 13 and adjust to suitable degree, can in oil well, carry out normal dosing work.The stress-free oil well of ring set also can not use communicating valve 12, only need open outlet valve 7, opens a drip trap 13, and adjusts to suitable degree, can carry out normal dosing work to oil well.
