Abstract: A yield estimation device for a low-yield shale gas reservoir includes: a separation tank, a pulse gas detector, and a methane concentration detector; wherein a liquid inlet is provided at an upper portion of the separation tank; an exhaust pipe is provided on a top of the separation tank, and the pulse gas detector is installed at a middle section of the exhaust pipe; the methane concentration detector is installed at a tail end of the exhaust; a valve is installed in a liquid outlet; a float is arranged in the separation tank, which is connected to the valve through a telescopic float rod. A yield estimation method includes steps of: inputting flowback fluid into the separation tank through the liquid inlet; discharging the air in the separation tank; performing gas-liquid separation; detecting and displaying the shale gas in real time with the pulse gas detector.

Abstract: A method and a device of predicting reservoir sand bodies based on a wind field-provenance-basin system are provided. The method includes: acquiring geological data of a to-be-predicted area, which includes several of core data, paleontological data, well logging data and seismic data; inputting the geological data into a preset wind field-provenance-basin system model, for generating beach-bar-sand-body formation-process-data for the to-be-predicted area, where the wind field-provenance-basin system model includes several of a paleo-provenance restoration tool, a paleo-wind force restoration tool, a paleo-wind direction restoration tool, a paleo-geomorphology restoration tool and a paleo-water depth restoration tool; and predicting distribution locations where the beach-bar sand bodies are distributed in the to-be-predicted area using geological methods and geophysical methods based on the beach-bar-sand-body formation-process-data.

Abstract: The invention relates to a non-invasive method to diagnose the changes of molecular structures of organism tissues from body surface and a dedicated apparatus. The apparatus is comprised of a Fourier Transform infrared spectrometer and a set of additional accessories. Said additional accessories include a mid-IR fiber optics sampling attachment, a fiber coupling part, and an infrared detector part. The detection method is comprised of placing the ATR probe of the dedicated apparatus on the skin surface of a region to be tested, and scanning more than one time in which the resolution of the apparatus is 1-32 cm?1 and the range of the spectrum is 800-4000 cm?1. It is possible to detect changes in molecular structures of living biological tissues in the early stages of cancer, and testees will not feel uncomfortable during testing. The method is easy to operate, quick, accurate, and it doesn't harm the body.
