Abstract
The utility model discloses a manual chemical dosing device for crude oil of a single well pipeline. The manual chemical dosing device comprises a chemical cylinder, wherein a piston is arranged in the chemical cylinder; a lead screw is arranged on the piston; a chemical inlet pipe is arranged on the side wall of the chemical cylinder and positioned below the piston; a first check valve is arranged on the chemical inlet pipe; the tail end of the chemical inlet pipe is connected with a chemical dosing device body; a chemical outlet pipe is arranged at the bottom of the chemical cylinder; a second check valve is arranged on the chemical outlet pipe. The manual chemical dosing device utilizes high pressure to directly input chemical liquor to an oil pipeline, and solves the problem that faults in the conventional chemical dosing process affect the regular production of oil fields; the manual chemical dosing device does not affect the normal production work of the oil fields, one person can complete the chemical dosing work, the workload is lowered, the human resources are saved, and higher practical and economic values are provided for the production units of the oil fields.
Description
Technical field
The utility model belongs to oil field equipment technical field, is specifically related to a kind of hand crude oil single well pipeline chemicals dosing plant.
Background technology
In oil recovery industry, after temperature reduces, thereby exploitation crude oil out there will be viscosity to increase the phenomenon that causes mobility variation, in the transportation of crude oil at petroleum pipeline, can cause travelling speed to slow down and situation that pipeline internal pressure increases, this has brought very big inconvenience to the normal production in oil field.In order to increase the mobility of crude oil; people can add liquid also to reduce viscosity of crude, increase mobility conventionally in the crude oil of petroleum pipeline; in prior art, people generally adopt the of short duration extracting device of oil of closing, open valve to the method for toppling over liquid in petroleum pipeline to the crude oil dosing in pipeline.Clearly, existing dosing process exists affects the normal shortcoming of producing in oil field.
Utility model content
The purpose of this utility model is to provide a kind of hand crude oil single well pipeline chemicals dosing plant, has solved the shortcoming that affects the normal production in oil field existing in existing dosing process.
The technical scheme that the utility model adopts is: hand crude oil single well pipeline chemicals dosing plant, comprise drug-containing jar, in drug-containing jar, be provided with piston, on piston, be provided with leading screw, on the sidewall of drug-containing jar, be provided with drug-feeding tube, drug-feeding tube is positioned at the below of piston, on drug-feeding tube, be provided with only valve first time, the end of drug-feeding tube is connected with chemicals dosing plant, and the bottom of drug-containing jar is provided with drug discharging tube, is provided with only valve on drug discharging tube second time.
Feature of the present utility model is also,
On drug-containing jar, be provided with upper end cover, leading screw is through upper end cover, the part that upper end cover contacts with leading screw be provided with leading screw on the spiral groove that adapts of screw thread.
On the other end of leading screw, be provided with handwheel.
The beneficial effects of the utility model are: hand crude oil single well pipeline chemicals dosing plant of the present utility model utilizes high pressure directly to input liquid in petroleum pipeline, solved the shortcoming that affects the normal production in oil field existing in existing dosing process, hand crude oil single well pipeline chemicals dosing plant of the present utility model does not affect the normal production work in oil field, a people can complete dosing work, reduced workload, saved manpower, field produces unit has been had to higher practicality and economic worth.
Accompanying drawing explanation
Fig. 1 is the structural representation of hand crude oil single well pipeline chemicals dosing plant of the present utility model.
In figure, 1. drug-containing jar, 2. upper end cover, 3. piston, 4. leading screw, 5. handwheel, 6. drug-feeding tube, 7. drug discharging tube, 8. chemicals dosing plant, 9. first time valve only, 10. second time valve only.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is elaborated.
The structure of the hand crude oil single well pipeline chemicals dosing plant that the utility model provides as shown in Figure 1, comprise drug-containing jar 1, in drug-containing jar 1, be provided with piston 3, on piston 3, be provided with leading screw 4, be provided with drug-feeding tube 6 on the sidewall of drug-containing jar 1, drug-feeding tube 6 is positioned at the below of piston 3, on drug-feeding tube 6, be provided with only valve 9 first time, the end of drug-feeding tube 6 is connected with chemicals dosing plant (8), and the bottom of drug-containing jar 1 is provided with drug discharging tube 7, is provided with only valve 10 on drug discharging tube 7 second time.
On drug-containing jar 1, be provided with upper end cover 2, leading screw 4 is through upper end cover 2, the part that upper end cover 2 contacts with leading screw 4 be provided with leading screw 4 on the spiral groove that adapts of screw thread.
On the other end of leading screw, be provided with handwheel 5.
Piston 3 is divided into the first half and the latter half two parts by drug-containing jar 1, in drug-containing jar 1 the latter half, a part of liquid is housed in advance, then drug discharging tube 7 is connected with the petroleum pipeline of oil extraction in oil field tree, rotation hand wheel 5 makes leading screw 4 drive piston 3 to move downward, drug-containing jar 1 the latter half pressure increases thereupon, owing to returning only valve, it is one-way conduction, when pressure reach 5 atmospheric pressure when above by make on drug-feeding tube 6 first time only valve 9 close, on drug discharging tube 7 second time only valve 10 open liquid in pipe flows into petroleum pipeline, complete dosing process; Then counter-rotating handwheel 5 makes leading screw 4 drive piston 3 to move upward, the pressure of drug-containing jar 1 the latter half reduces thereupon, thus when pressure is less than 5 atmospheric pressure by make on drug discharging tube 7 second time only valve 10 close, on drug-feeding tube 6 first time only valve 9 open the liquid in chemicals dosing plant 8 flowed in drug-containing jar 1.So circulation operation repeatedly, can realize repeatedly the object for the interior dosing of petroleum pipeline of oil extraction in oil field tree.
By the way, hand crude oil single well pipeline chemicals dosing plant of the present utility model utilizes high pressure directly to input liquid in petroleum pipeline, solved the shortcoming that affects the normal production in oil field existing in existing dosing process, hand crude oil single well pipeline chemicals dosing plant of the present utility model does not affect the normal production work in oil field, a people can complete dosing work, reduced workload, saved manpower, field produces unit has been had to higher practicality and economic worth.
