The invention discloses a verticality detection assembly for drilling construction, which includes a sliding column, a linkage rod is fixed on the upper end of the sliding column, and connecting rods are hinged on the two side walls of the lower end of the sliding column, and the movable end of the connecting rod is installed There are rollers, and the lower part of the lower column is provided with a card slot, and the annular chassis is threadedly matched with the card slot, and the inner side of the chassis is provided with a conical surface that matches the hinged end of the connecting rod; it also includes two pressure sensors. The pressure sensor is fixed on the lower column and communicates with the external controller through the linkage rod through the wire. A spring is installed on the connecting rod, and the movable end of the spring is connected with the pressure sensor. The invention is simple and fast in operation, can quickly detect the verticality of the oil well, and because of the adjustable performance of the connecting rod, while improving the applicability, it solves the problems of complex structure and inconvenient use of the previous measuring tools.
Description
technical field [0001] The invention relates to the field of oil well platform construction, in particular to a verticality detection component used for drilling construction. Background technique [0002] The vertical section of the horizontal well has relatively strict requirements on its verticality during construction. Generally, the verticality of the oil well needs to be kept within a certain angle range to meet the follow-up operations. When digging the oil well, it is necessary to reasonably detect the verticality of the oil well. In order to prevent well deviation from affecting oil production, therefore, tools are needed for measurement at any time. The previous measurement tools are not only complex in structure, but also extremely troublesome to use. Each measurement takes a long time, which greatly slows down the progress of well digging. At the same time, because the oil well is deep, when excavating tools are excavating, some tools will be affected by the bott...
