Embodiment

[0036] Such as Figure 1-5 As shown, a new type of water distributor adjustment structure includes a fairing 1, a compression spring 2, a main body 3, a rotary vane, a rotating core, a fixed cylinder, a decompression bearing 7, a main shaft 11, a dynamic seal 12, a motor assembly 13 and a lower One deck of aqueduct 16.

[0037] The body 3 has internal passages for the circulation of the injection water. There are at least two fixed barrels in the internal channel of the main body 3, and the fixed barrels form a seal with the main body through an O-ring to realize layered isolation and prevent water injection from layering. The fixed cylinder is provided with a central channel and a water injection channel, the central channel is used for water flow into the rear of the inner channel, the water injection channel is used for water flow into the opposite water injection port, and the water injection port is set on the main body 3 for water flow into in the oil layer.

Abstract

The invention discloses a novel water distributor adjusting structure. The novel water distributor adjusting structure comprises a main body with an internal channel, at least two fixed cylinders are arranged in the internal channel of the main body, a central channel and a water injection channel are arranged on each fixed cylinder, rotating rotary vanes are arranged in the internal channel of the main body, the rotary vanes are arranged at inlets of the water injection channels in a matched mode, and water injection ports opposite to the water injection channels are formed in the main body. The novel water distributor adjusting structure has the advantages that when one water distributor is used for controlling water injection of two or more stratums, adjustment is achieved through one set of adjusting structure; when water is injected into the current layer and the next layer, controllable switching of completely different water injection layers is achieved, and the switching operation is relatively independent; an overrunning clutch principle is adopted, and two sets of rotating cores which rotate forwards and reversely and fixed cylinders are used for completing injection flow and injection layer control over the two stratums; the whole structure is higher in integration degree, more compact in design and smaller in size; and the rotary cores and the end faces of the fixed cylinders are ground and then combined together, switching and control over the water flow injection area are achieved through end face sealing, and therefore the water flow injection amount is adjusted.

Description

technical field [0001] The invention relates to an oilfield water injection instrument, in particular to a novel adjustment structure of a water distributor. Background technique [0002] In the development of heterogeneous multi-reservoir, in order to strengthen the medium and low permeability layers and control the water injection of high permeability layers, according to the injection requirements, the water injection method of layered control injection in the water injection well has become a solution in the process of oilfield development. The contradiction between layers is an important means to maintain long-term stable and high production of oilfields and improve oil recovery. [0003] At present, in the development process of oilfield water injection instruments and tools, water injection instruments have complex structures, large volumes, and limited functions, which cannot meet the increasing demand for water injection. Therefore, the existing field has begun to d...
