Abstract

The invention discloses a detection device for the inclination of a horizontal well, which comprises a sliding rod, a connecting rod is fixed on the upper end of the sliding rod, a connecting rod is hingedly connected to the two side walls of the middle part of the sliding rod, and the movable end of the connecting rod is installed with an adjusting rod. The lower part of the sliding rod is provided with a clamping groove, the annular base is threaded with the clamping groove, and the inner side of the base is provided with a conical surface matching the hinged end of the connecting rod; it also includes two pressure sensors, the The pressure sensor is fixed on the sliding rod and communicates with an external controller through a wire passing through the connecting rod. 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 quick to operate, can quickly detect the inclination of the oil well, and because of the adjustable performance of the connecting rod, while improving the applicability, the problems of complex structure and inconvenient use of the previous measuring tools are solved.

Description

technical field [0001] The invention relates to the field of oil well drilling construction, in particular to a detection device for the inclination of a horizontal well. Background technique [0002] The vertical section of the horizontal well has strict requirements on the inclination. Generally, the inclination of the oil well must be controlled within a reasonable range to meet the follow-up operations. When excavating the oil well, it is necessary to reasonably detect the inclination of the oil well to avoid the influence of the well inclination. Oil extraction, therefore, requires tools to measure at any time. The previous measuring 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. Contents of the invention [0003] The object of the present invention is to provide a detection device for the inclination of a horizontal well, which solves the proble...
