Southwest Oil and Gas Field: Development and Application of the First Mobile Inspection Vehicle in Western Sichuan

The Southwest Oil and Gas Field Engineering and Technology Research Institute has developed a first set of return-to-liquid recovery vehicle-mounted mobile skid-mounted inspection vehicles for the problem of large amount of liquid returning fluid generated by sand fracturing in western Sichuan and high processing costs. The detection of the returning and discharging liquid at the fracturing site provides a scientific basis for the reuse of the returning liquid. The successful application of the mobile testing vehicle realizes the reuse of the mud and the fracturing fluid, which reduces the cost and promotes the promotion. Clean manufacturing.

The picture shows that on October 12, the laboratory personnel tested the fracturing and returning liquid at the construction site of the 21-48HF well in Xinsha.

Folding Knife

Folding knife, a kind of knife, can be folded. The folding knife is mainly connected with a knife body which can be rotated into by a pivot assembly at the front end of the handle. The knife body is provided with a safety buckle relative to the side of the knife body, and an elastic strip relative to the back end of the knife body. The back end of the knife body is provided with a stop part and a stop concave part which can be butted by the elastic strip, and the safety buckle has a tilted elastic buckle part, The elastic strip is arranged in the holding chamber of the handle, one end of which is fixed, and the other end of which is connected with the stop part of the tool body, so as to provide the thrust to assist the rotation of the handle when the tool body is rotated out of the handle, In addition to the simple semi-automatic operation mode of turning out and positioning by using the elastic auxiliary push knife body, the overall thickness of the folding knife is reduced by the refined and simplified structural design, which is convenient for the collection and carrying of the folding knife and makes the operation of the folding knife easier.
