Embodiment
[0029] Such as Figure 1-Figure 2 Shown, the cleaning liquid cleaning method that the present invention is used for petroleum pipeline, comprises:
[0030] The first step is to assemble a simple cleaning device for oil pipelines with a cleaning body and a fixed body;
[0031] In this embodiment, the fixed body includes a fixed pulley 6 , a bracket 7 for installing the fixed pulley 6 , and a stopper tooth 8 arranged on the bracket 7 . The support 7 is circular, and the fixed pulley 6 is installed at the center of the support 7 through a connecting rod 9 . The number of upper limit latches 8 on the bracket 7 is more than 3, and the more than 3 limit latches 8 are evenly arranged on the bracket 7 in a circular shape. A bearing bar 10 is also arranged on the support 7 .
[0032] The cleaning body includes a cylindrical support cylinder 1, a cleaning body 2 arranged on the side wall of the support cylinder 1, a wire through hole 3 arranged at a position adjacent to the central a...

The invention discloses a cleanout fluid cleaning method for a petroleum pipeline. The problems that the petroleum pipeline is longer, so that a longer push-and-pull rod is needed to be used in a matched manner, and then matter in the pipeline can be effectively removed are solved. The cleanout fluid cleaning method includes the steps that (1) a simple and convenient cleaning device for the petroleum pipeline with a cleaning body and a fixing body is assembled; (2) the petroleum pipeline has two ends which are named as an extending-in end and an extending-out end, and the free end of a first pulling rope and the free end of a second pulling rope extend into the petroleum pipeline from the extending-in end and extend out of the petroleum pipeline from the extending-out end; (3) the cleaning body extends into the petroleum pipeline from the extending-in end, and the fixing body is fixed to the extending-in end of the petroleum pipeline; and (4) the first pulling rope and the second pulling rope are pulled to achieve movement of a support barrel, the first pulling rope and a third pulling rope are pulled at the same time, cleanout fluid in a cleanout fluid containing bag is released, and the inner pipe wall of the petroleum pipeline is cleaned through joint effects of a cleaning body and the cleanout fluid in the movement process. The cleanout fluid cleaning method has the beneficial effects of being convenient to operate and the like.
Description
technical field [0001] The invention relates to a cleaning method, in particular to a cleaning liquid cleaning method for oil pipelines. Background technique [0002] With the continuous development of the petroleum industry, the large number of various oil injection wells has increased the demand for various oil pipelines and water pipelines. After long-term use of oil and water pipelines, there will be many oil stains and dirt on the inner wall of the oil pipelines. Impurities, when the oil and water pipes are used for dynamic monitoring work such as oil well testing and pressure measurement, and when oilfield water injection is relatively clogged, it will affect the monitoring results and bring difficulties to water injection. inconvenient. Regular cleaning and maintenance of oil transmission pipelines is beneficial to prolong the life of pipelines, improve transmission efficiency, reduce energy consumption and leakage. [0003] Disclosed in the patent CN201520628436.5 ...
