Problems solved by technology

[0002] At present, in the technical field of logging while drilling for oil drilling, the near-bit measuring instrument is generally close to the drill bit, and the upper end is connected with the drilling instrument through the screw drilling tool, but the directional parameter measuring point of the conventional near-drilling measuring instrument lags behind the drill bit In this way, the oil / gas and oil / water interfaces cannot be effectively measured and distinguished, and faults cannot be found and avoided in time, resulting in a low sandstone drilling rate

Abstract

The invention discloses a near-bit orientation parameter measuring device while drilling. The device comprises instrument bins, a well inclination sensor, a battery module and a main control module, wherein the instrument bins for orientation parameter measurement are arranged on a near-bit short joint while drilling, the number of the instrument bins is four, and the instrument bins are uniformly distributed on the circumference of the near-bit short joint while drilling; one of the instrument bins comprises the high-performance well inclination sensor; the main control module is electrically connected with the battery module and the well inclination sensor and used for acquiring well inclination data sent by the well inclination sensor; and the main control module is used for calculating the well inclination of a near bit while drilling according to the data uploaded by the well inclination sensor and the installation direction of the well inclination sensor. The device can be used for measuring the engineering parameters near the bit, so that the engineering technicians can timely adjust the borehole locus according to the parameters, the borehole locus is ensured to pass through reservoirs all the time, and the sandstone drilling rate is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a device for measuring directional parameters near a drill bit while drilling. Background technique [0002] At present, in the technical field of logging while drilling for oil drilling, the near-bit measuring instrument is generally close to the drill bit, and the upper end is connected with the drilling instrument through the screw drilling tool, but the directional parameter measuring point of the conventional near-drilling measuring instrument lags behind the drill bit In this way, the oil / gas and oil / water interfaces cannot be effectively measured and distinguished, and faults cannot be found and avoided in time, resulting in a low sandstone drilling rate. Contents of the invention [0003] The purpose of the present invention is to provide a directional parameter measurement device near the drill bit while drilling, which can measure the engineering parameters...
