Problems solved by technology

However, there are obvious defects in this dispenser: the electrical part in this dispenser needs to be completely installed in a closed, dry, and waterproof space, so the sealing performance of the sealing structure in the dispenser is required to be high. In addition, the underground The higher temperature requires high temperature resistance of the electric

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the drawings:

[0034] The present invention includes upper joint 1, upper cylinder 2, adapter 3, lower cylinder 4, mounting main body 5, lower joint 6, upper center tube 8 and lower center tube 7, upper joint 1, upper cylinder 2, adapter 3, lower The barrel 4, the mounting body 5, and the lower joint 6 are sequentially connected by threads from top to bottom, thereby forming the casing of the dispenser.

[0035] The upper end of the upper central pipe 8 is inserted into the upper joint 1, and the lower end of the upper central pipe 8 is screwed to the adapter 3, thereby forming an annular space between the upper central pipe 8 and the upper cylinder 2. An air circuit converter 10 is installed in the space, and the air circuit converter 10 is fixed on the upper center tube 8 through a jack wire;

[0036] The upper joint 1 and the adapter 3 are both provided with a linear air passage 9. The upper end sur...

Abstract

The invention belongs to the field of oil field water injection tools, in particular to an injection distribution device, which comprises an upper joint, an upper cylinder, an adapter, a lower cylinder, an installation main body, a lower joint, an upper central pipe and a lower central pipe. The upper joint, the upper cylinder, the adapter and the lower cylinder, the installation main body and thelower joint are sequentially connected through threads from top to bottom to form a shell of the injection distribution device, the upper end of the upper central pipe is inserted into the upper joint, an air pipe connected with the adapter passes through the installation main body and the lower joint and then leads to the outer side of the injection distribution device, two ends of the lower central pipe are respectively inserted between the adapter and the installation main body, a control valve assembly is arranged in the annular space, and a water nozzle assembly is arranged in the installation main body. Compared with a mechanical injection distribution device, the device has the advantages that a tool does not need to be taken off when water is dispensed, and the operation cost is greatly reduced; and compared with an electric control injection distribution device, the device has no strict working condition requirement, so the working stability is better, and the reliability ishigher.

Description

Technical field [0001] The invention belongs to the field of oilfield water injection tools, and in particular relates to a dispenser. Background technique [0002] The injector is a commonly used downhole tool in the tertiary oil recovery process of the oilfield. Its function is to adjust the polymer injection volume of each reservoir to better achieve the purpose of increasing production. At present, most of the dispensers used in oil fields are purely mechanical. After the dispenser is installed, it is necessary to take out the plug in the dispenser through downhole operations, and replace the water nozzle in the plug. To achieve the purpose of adjusting the injection volume, this adjustment method often occurs when the fishing device is stuck, and the success rate of fishing is low, which seriously affects the operation efficiency. [0003] In addition, there is also an electronically controlled dispenser in the prior art. When in use, the cable on the ground is connected to t...
