Abstract

The invention relates to the technical field of a wireless while-drilling testing instrument and in particular relates to a wireless while-drilling compound multipoint instrument comprising a nonmagnetic drill collar, a drill collar joint, a wireless while-drilling instrument, a multipoint probe, a multipoint instrument bin, a pallet buffer and a dropping and fishing self-floating carrier, wherein the outer side of the lower end of the nonmagnetic drill collar is fixedly connected together with the inner side of the upper end of the drill collar joint by virtue of threads; the wireless while-drilling instrument is fixedly arranged in the nonmagnetic drill collar and the drill collar joint; the upper end of the wireless while-drilling instrument is fixedly provided with a wireless while-drilling fishing spear; and the inner side of the lower part of the pallet buffer is in a conical-platform shape with a narrow upper part and a wide lower part. In the wireless while-drilling compound multipoint instrument, the structure is reasonable and compact, and the use is convenient; the drilling-down measurement is carried out by the multipoint instrument of the wireless while-drilling instrument; and after measurement, a fishing device and a buoyancy bin float to a wellhead in a dropping-fishing and self-floating manner; and compared with single-point measurement of the wireless while-drilling instrument, according to the invention, the process drilling up and down is omitted, the drilling efficiency is improved, the drilling risk is reduced, and simultaneously the drilling period is shortened.

Description

Technical field [0001] The invention involves the technology field of wireless drilling instruments, which is a multi -point instrument in wireless drilling. Background technique [0002] Multi -point electronics is an electronic instrument that is widely used in oil drilling in petroleum drilling. Electronic instruments with oblique eye wells and orientation are important tools for mastering and controlling the trajectory of the well.When drilling, you must take a lot of points to measure one more point. Because one more risk is wasting, it not only wast the time, but also extends the drilling cycle; affects the speed -up and efficiency of drilling. Invention content [0003] The present invention provides a multi -point instrument with a wireless drilling composite, which overcomes the lack of the above -mentioned existing technologies. It can effectively solve the single -point measurement of wireless drilling instruments, extend the drill cycle, affect the speed, efficiency ...
