The utility model discloses simple structure, convenient to use, reliable operation for during the well head manifold of oil field borehole operation connects, can be according to the construction equipment needs of difference, change into the mode of multiple connections such as flange, union or clamp wantonly through the combination, thereby bring the convenience for field operation.

Description

A combined tee

技术领域：本实用新型涉及一种矿场施工机具，特别是用于油田井下作业施工的一种组合式三通。Technical field: The utility model relates to a mine construction machine tool, especially a combined tee used for oilfield underground construction.

背景技术：本实用新型前，各油田在气井完井测试或油井地层改造等井下作业的井口管汇连接中，多采用普通的专用三通接头，因此要根据不同的施工设备配备法兰、油壬或卡箍等多种连接方式的三通接头，给现场操作带来不便。Background technology: Before this utility model, in the wellhead manifold connection of downhole operations such as gas well completion testing or oil well formation reformation in various oil fields, ordinary special-purpose tee joints were mostly used, so flanges, oil pipes, etc. should be equipped according to different construction equipment Tee joints with multiple connection methods such as non-clamps or clamps bring inconvenience to on-site operations.

发明内容：本实用新型的目的是：为油田井下作业的井口管汇连接提供一种组合式三通，由于该装置能够根据不同的施工设备需要，通过组合任意改变为法兰、油壬或卡箍等多种连接的方式，从而给现场操作带来方便。Summary of the invention: The purpose of this utility model is to provide a combined tee for the wellhead manifold connection of the downhole operation in the oil field, because the device can be changed into a flange, a non-stick or a card according to the needs of different construction equipment through combination. A variety of connection methods such as hoops, which bring convenience to on-site operations.

本实用新型的目的是通过以下措施来实现的：一种组合式三通，是由三通状的主体构成，且主体的接头为带有钢圈槽的法兰盘，其特征是在主体的法兰盘接头内孔壁上加工有螺纹。The purpose of this utility model is achieved through the following measures: a combined tee is composed of a tee-shaped main body, and the joint of the main body is a flange with a steel ring groove, which is characterized in that Threads are processed on the wall of the inner hole of the flange joint.

本实用新型的目的还可以通过以下措施来实现：主体的法兰盘接头可通过内孔壁上的螺纹连接油壬接头或卡箍接头。The purpose of this utility model can also be achieved by the following measures: the flange joint of the main body can be connected to the oil nonel joint or the clamp joint through the thread on the inner hole wall.

本实用新型结构简单、使用方便、工作可靠，用于油田井下作业的井口管汇连接中，能够根据不同的施工设备需要，通过组合任意改变为法兰、油壬或卡箍等多种连接的方式，从而给现场操作带来方便。The utility model has the advantages of simple structure, convenient use and reliable operation. It is used in the connection of the wellhead manifold in the downhole operation of the oil field. According to the needs of different construction equipment, it can be arbitrarily changed into various connections such as flanges, oil rings or clamps through combination. way, so as to bring convenience to on-site operation.

附图说明：图1为组合式三通的结构示意图，图2为油壬接头的结构示意图，图3为卡箍接头的结构示意图。Description of drawings: Figure 1 is a structural schematic diagram of a combined tee, Figure 2 is a structural schematic diagram of a non-oil joint, and Figure 3 is a structural schematic diagram of a clamp joint.

具体实施方式：组合式三通是由三通状的主体(图1)构成，主体(图1)的接头为带有钢圈槽的法兰盘，在主体(图1)的法兰盘接头内孔壁上还加工有螺纹；主体(图1)的法兰盘接头可通过内孔壁上的螺纹连接油壬接头(图2)或卡箍接头(图3)。The specific embodiment: the combined tee is composed of a tee-shaped main body (Fig. 1), the joint of the main body (Fig. 1) is a flange with a steel ring groove, and the flange joint of the main body (Fig. 1) Threads are also processed on the wall of the inner hole; the flange joint of the main body (Figure 1) can be connected to the oil nonel joint (Figure 2) or the clamp joint (Figure 3) through the thread on the inner hole wall.

组合式三通的工作原理和使用方法是：在油田井下作业的井口管汇连接中可施工设备需要，通过三通状的主体(图1)上带有钢圈槽的法兰盘与钢圈结构的法兰或胶垫结构的法兰直接连接；也可通过其法兰盘接头内孔壁上的螺纹连接油壬接头(图2)或卡箍接头(图3)，再与油壬或卡箍等接头连接；还可通过其法兰盘接头内孔壁上的螺纹与其他各类接头连接。由于本装置通过组合后能够适应多种连接方式，因而在井下作业中时无需配备多种连接方式的三通接头，从而给现场操作带来方便。The working principle and usage method of the combined tee is: in the wellhead manifold connection of the downhole operation in the oil field, the construction equipment can be required, and the flange and the steel ring with the steel ring groove on the main body of the tee (Fig. 1) can be used. The flange of the structure or the flange of the rubber pad structure is directly connected; it can also be connected to the oil nonel joint (Figure 2) or the clamp joint (Figure 3) through the thread on the inner wall of the flange joint, and then connected to the oil nonel or It can be connected with joints such as clamps; it can also be connected with other types of joints through the threads on the inner wall of the flange joint. Since the device can adapt to multiple connection modes after being combined, it is not necessary to be equipped with tee joints with various connection modes during downhole operations, thereby bringing convenience to on-site operations.
