Abstract

The utility model belongs to an oil field well mouth device, and relates to a thermal recovery well mouth process, in particular to an injection-extraction separated thermal recovery well mouth process device. The injection-extraction separated thermal recovery well mouth process device is characterized in that a steam-injection bypass line assembly and an oil-extraction bypass line assembly are respectively communicated with connectors on two sides of a small four-way component of a thermal recovery Christmas tree through thermal recovery valves and are independently arranged on two wings of the thermal recovery Christmas tree. After an existing injection-extraction integrated structure is improved to be the injection-extraction separated thermal recovery well mouth process, the injection-extraction separated thermal recovery well mouth process device has the advantages that line sweeping, steam injection, well closing, open flow, oil extraction and other processes are not influenced by one another and can be carried out smoothly, operations are safe, and thermal recovery efficiency is improved.

Description

Notes are adopted and are separated the thermal recovery wellhead flow passage device

Technical field

The utility model belongs to the oil-field well head device field, relates to the thermal production well mouth flow process, proposes a kind of notes and adopts and separate the thermal recovery wellhead flow passage device.

Background technology

Existing oil thermal recovery Well head flow path adopts is that external steam injection bypass line first is the Y shape again with the oil recovery bypass line and is to be communicated with the thermal recovery production tree of thermal production well mouth by Thermal extracting valve after a pipeline, in running, to exist when pipeline purging difficulty large for this device, the high steam string is prone to safety problem to middle force feed road, the operations such as pipeline purging, steam injection, vexed well, open flow, oil recovery are influential mutually, job run is hindered, the defectives such as thermal recovery Efficiency Decreasing.

Summary of the invention

The inventor is in the manufacturing activity of being engaged in for many years the oil thermal recovery Well head flow path, reflect according to the user, find that existing thermal production well mouth flow process exists certain defect, through improving, purpose is to provide a kind of notes to adopt separation thermal recovery wellhead flow passage device, adopt steam injection, recover the oil and separate, can solve preferably the technical problem that existing thermal production well mouth flow process exists.

technical solution adopted in the utility model is that a kind of notes of design are adopted separation thermal recovery wellhead flow passage device, its structure comprises: the thermal recovery production tree, steam injection bypass line assembly and emptying bypass line assembly, oil recovery bypass line assembly and water mixing pipeline assembly, and securing member, wherein, steam injection bypass line assembly, oil recovery bypass line assembly is communicated with by two side interfaces of the little four-way on Thermal extracting valve and thermal recovery production tree respectively, separate and be arranged on thermal recovery production tree both wings, emptying bypass line assembly accompanies and is communicated with steam injection bypass line assembly, and be communicated with big four one side interface on the thermal recovery production tree by Thermal extracting valve, water mixing pipeline assembly accompanies and is communicated with setting with oil recovery bypass line assembly.

Described Thermal extracting valve adopts long-neck hollow out support, reduces temperature and upwards transmits.

The utility model is owing to adopting such scheme, steam injection bypass line and oil recovery bypass line are annotated the thermal production well mouth flow process of adopting combined structure, be improved to and annotate the thermal production well mouth flow process of adopting isolating construction, difficulty is large when pipeline purging, efficient is low to have solved preferably existing oil thermal recovery Well head flow path, the safety problem of high steam string to the middle force feed road, several procedures such as pipeline purging, steam injection, vexed well, open flow, oil recovery are independent of each other, carry out smoothly, greatly improve thermal recovery efficient.

Description of drawings

Fig. 1 represents that the utility model is annotated and adopts the structural representation that separates the thermal recovery wellhead flow passage device.

In Fig. 2 presentation graphs 1, water mixing pipeline assembly A is to structural representation.

The specific embodiment

In conjunction with the accompanying drawings and embodiments, further illustrate concrete structure of the present utility model.

the utility model is annotated and is adopted the embodiment that separates the thermal recovery wellhead flow passage device, referring to Fig. 1, its structure comprises: thermal recovery production tree 1, steam injection bypass line assembly 2 and emptying bypass line assembly 3, oil recovery bypass line assembly 5 and water mixing pipeline assembly 6, steam injection bypass line assembly 2 wherein, oil recovery bypass line assembly 5 is respectively by Thermal extracting valve 4.1, 4.2 be connected with two side interfaces of little four-way 1.1 on thermal recovery production tree 1, separate the both wings that are located at thermal recovery production tree 1, emptying bypass line assembly 3 accompanies to be communicated with steam injection bypass line assembly 2 and to pass through Thermal extracting valve 4.1 side interface corresponding to the big four 7 on thermal recovery production tree 1 and is communicated with, water mixing pipeline assembly 6 accompanies with by oil recovery bypass line assembly 5 is communicated with the another side that is arranged on thermal recovery production tree 1, Thermal extracting valve 4.1, 4.2 support adopt long-neck hollow out support 8.

This notes of the present utility model are adopted and are separated the thermal recovery wellhead flow passage device, through model machine examination installation and operation, have overcome the problem that existing thermal production well mouth flow path device exists, and are subject to well site workman's favorable comment.
