BZM-F self-floating magnetic single shot instrumen

Scope : measure the well track in petroleum drilling technology, which has capability of recording the inclined angle, Azimuth of well and the face angle of high-side tool used for elbow on the film by means of optical imaging. Feature: Under the effect of buoyancy, self-floating magnetic single shot instruments can be delivered to proper position to perform measurement by turning on the pump, and it will be upraised to well top if pump had been shut down. It is unnecessary to throw Kelly bar, measure well hoisting winch and cycle the mud for adjusting prior to measuring well, and the pump can be turned on, the rotating drilling tool can be lifted and the drilling operation can be started at any time, therefore measuring process can be simplified, the well measuring period can be saved, drilling failure can be avoided effectively and depth of well measuring can be deepened.
