Abstract

The invention provides a nuclear magnetic resonance logging system, which comprises a mud pipe, a controller, a controllable pump, a spectrometer, a wireless transmitting and receiving module, a detection pipe and a detection device, wherein the mud pipe is used for extracting downhole drilling fluid; one end of the mud pipe extends to the downhole and the other end is connected with a drilling fluid pool; one end of the detection pipe is communicated with the mud pipe and the other end is communicated with the outlet of the controllable pump; the inlet of the controllable pump is communicated with the mud pipe; the detection pipe is sleeved with the detection device; the detection device is connected with the spectrometer; and the spectrometer and the controllable pump communicate with the controller via the wireless transmitting and receiving module. According to the nuclear magnetic resonance logging system, real-time drilling fluid detection and remote drilling fluid detection control are realized, defects that wiring of wired communication is complicated, fault points are hard to find when fault happens and the like are overcome, and adaptability and stability of the nuclear magnetic resonance logging system are enhanced.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance, in particular to a nuclear magnetic resonance mud logging system. Background technique [0002] Drilling fluid is the blood of oil drilling. In addition to cleaning the bottom of the well, carrying cuttings, lubricating the drill bit, balancing formation pressure, and transmitting hydraulic power, etc., it has a series of functions to ensure safe drilling. It also discovers underground oil and gas, describes formation lithology and An important information carrier for evaluating reservoir properties. Therefore, it is very important to detect and describe the performance of drilling fluid in the process of petroleum drilling control. [0003] In order to test the performance of the drilling fluid, samples of the drilling fluid can be collected at the wellhead during the drilling process, and tested by nuclear magnetic resonance technology in the laboratory, which can measure th...
