Description

Technical Field

[0001] The utility model relates to the field of water quality detection devices, in particular to a novel oilfield water injection water quality detection instrument. Background Art

[0002] During the oil field exploitation process, as the exploitation time increases, the energy of the oil layer itself will be continuously consumed, causing the oil layer pressure to continue to drop, a large amount of underground crude oil to degas, the viscosity to increase, the oil well output to be greatly reduced, and even the spraying and production will stop, resulting in a large amount of dead oil remaining underground that cannot be extracted. In order to make up for the underground deficit caused by the extraction of crude oil, maintain or increase the oil layer pressure, achieve high and stable production of the oil field, and obtain a higher recovery rate, the oil field must be injected with water, and water injection equipment is used to inject water of qualified quality from the injection well into the oil layer to maintain the oil layer pressure. This process is called oil field water injection. Oil field water injection is one of the important means to replenish energy to the formation and improve the oil field recovery rate during the development of the oil field. The level of water injection well management technology determines the effectiveness of oil field development, and also determines the length of the oil field development life. After the water is injected into the well, it will be tested using water quality testing instruments.

[0003] However, there are some shortcomings in the current water quality testing instruments. When the water quality testing instrument is in use, the user holds the tester body and then puts the test head into the liquid to be tested. The test head is connected to the tester body through a wire. When the test is completed, the test head cannot be effectively placed and protected. Therefore, when holding the tester, the user needs to hold the test head and the tester body in his hand at the same time, which is more troublesome. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The front end of the detector body 1 is fixedly installed with the wire 2, one end of the wire 2 is fixedly installed with the detection head 3, a first fixing block 5 is fixedly installed on the lower surface of the front end of the detector body 1, a second fixing block 4 is fixedly installed on the lower surface of the rear end of the detector body 1, and an arc plate 6 is movably installed between the first fixing block 5 and the second fixing block 4.

[0022] An annular groove 402 is provided on the surface of the second fixing block 4 opposite to the first fixing block 5, and an axial hole 401 is provided on the surface of the second fixing block 4 and in the middle of the annular groove 402; an arc-shaped groove 501 is provided on the surface of the first fixing block 5 opposite to the second fixing block 4, a clamping hole 502 is provided on the surface of the first fixing block 5, and a through opening 503 is provided on the inner lower surface of the clamping hole 502. The cooperation between the arc-shaped groove 501 and the arc-shaped clamping strip 603 can assist the arc plate 6 to rotate smoothly; a first stopper 601 is fixedly installed on the surface of one end of the arc plate 6, and a second stopper 605 is fixedly installed on the surface of the other end of the arc plate 6, and the surface of the second stopper 605 A clamping hole 502 is also provided on the surface, and a through opening 503 is also provided on the inner lower surface of the clamping hole 502; a clamping ring 604 is fixedly installed on one side surface of the No. 1 stopper 601, a knob 602 is fixedly installed on the surface of the No. 1 stopper 601 and located in the middle of the clamping ring 604, and an arc-shaped clamping strip 603 is fixedly installed on one side surface of the No. 2 stopper 605. The arc plate 6 can be conveniently rotated by using the knob 602, and there is a certain friction force between the clamping ring 604 and the annular clamping groove 402; the clamping ring 604 is movably embedded in the annular clamping groove 402, and the arc-shaped clamping strip 603 is movably embedded in the arc-shaped clamping groove 501; the knob 602 passes through the shaft hole 401 and is fixed to the No. 1 stopper 601.

[0023] It should be noted that the utility model is a novel oilfield water injection water quality detection instrument. During use, when the detection head 3 is not in use, the detection head 3 is placed under the detection instrument body 1, and the wire 2 at one end of the detection head 3 is stuck in the through opening 503. When the detection head 3 is fitted with the arc plate 6, the arc plate 6 is rotated by the knob 602. When the arc plate 6 is flipped at a certain angle, the arc plate 6 can support the detection head 3. Since there is a certain friction between the retaining ring 604 and the annular retaining groove 402, the rotated arc plate 6 will not flip easily. In this way, the detection head 3 can be restricted between the arc plate 6 and the detection instrument body 1, thereby effectively placing and protecting the detection head 3.
