| titleOfInvention | A controllable source density logging device while drilling |
| abstract | The invention relates to a device for logging the density of a controllable source while drilling, comprising an independent controllable neutron source while drilling and a density detection system while drilling. The radioactive source is an independent warehouse of a controllable neutron source while drilling, including a controllable source body while drilling, a neutron tube compression cylinder and a shielding body, and a neutron source is installed in the neutron tube compression cylinder; The detection system includes a detector body, a short source distance detector, a thermal neutron detector, a long source distance detector, a central processing circuit and an ultrasonic caliper measurer; the central processing circuit includes a microprocessor, signal amplification, shaping and screening Circuits, memories, interface circuits, bus drivers and buses. The controllable-while-drilling source of the present invention is installed in the pressure-resistant tube of the neutron tube and in the body of the controllable-while-drilling source to form an independent controllable-while-drilling neutron source, which excites high-energy fast neutrons when high-voltage electricity is applied. In the process of fast neutrons passing through the formation, the gamma rays are attenuated, and the attenuation of the gamma rays also mainly depends on the electron density that constitutes the formation. |
