Microchip automatic injection device and method

Abstract

The invention provides a microchip automatic injection device, which comprises a three-way valve, the three-way valve comprises a valve A, a valve B and a valve C, an inlet of the valve A is communicated with a microchip input port, and an outlet of the valve A is communicated with an inlet of the valve B through a first pipeline; the activation bin is arranged on the first pipeline, an inlet of the activation bin is communicated with an outlet of the port A, an outlet of the activation bin is communicated with an inlet of the port B, and the activation bin is used for activating the microchip; the storage bin is communicated with the outlet of the port B through a second pipeline and is used for storing the microchip fed from the feeding port; and the hydraulic driving mechanism is used for injecting the microchip communicating liquid stored in the storage bin into the drilling fluid circulating pipeline. The microchip automatic injection device injects one or more microchips into slurry in a drill rod, so that the microchips circularly enter the underground along with the slurry to realize full-shaft and while-drilling measurement.

Description

technical field [0001] The invention belongs to the field of oil drilling, and more specifically relates to a microchip automatic injection device and method. Background technique [0002] In modern petroleum drilling engineering, especially with the comprehensive transfer of the petroleum industry from land to sea, it is necessary to keep track of various parameters in the wellbore (such as temperature, pressure, wellbore trajectory, etc.) to ensure drilling operations. Can be implemented normally and safely. With the implementation of more and more extended-reach wells, deep wells, ultra-deep wells, especially deep-sea drilling, the acquisition of various parameters of the wellbore becomes more and more critical. In many cases, it has become the key to the successful completion of drilling operations. [0003] The transmission downhole measurement system can only be configured with a fixed number of sensors, and the sensors are installed at a fixed position on the drill ...

AI Technical Summary

Problems solved by technology

[0003] The transmission downhole measurement system can only be configured with a fixed number of sensors, and the sensors are installed at a fixed position on the drill pipe, so it can only measure parameters at a fixed position in the wellbore, such as data measurement near the drill bit, and cannot perform measurement while drilling As well as the measurement of the entire wellbore data, at the same time, as the drilling depth increases, the reliability of the measurement will also decrease, and the cost will increase accordingly
