DEVICE FOR CONTROLLING EXCAVATION AND OPERATION OF A GAS WELL Russian patent published in 2004 - IPC

FIELD: oil and gas extracting industry.

SUBSTANCE: device has cylindrically shaped body, at the top of which mounting assembly is placed, inside the body sensors of axial flow loss and horizontal flow are placed, sensors of moisture, pressure, noise, temperature, gamma-armor, sleeve locator, power supply unit and electronic plates, on the body a localizer is placed for centering the device along well axis. Body diameter of axial gas flow loss sensor is larger than device body diameter and has axial gas inlets and outlets, on the body of axial gas loss sensor a skirt localizer is additionally placed for centering device along well axis and for directing main gas flow from the mouth to pit-face through inlets and outlets of body of axial flow loss sensor, in the body of device inlets and outlets for horizontal flow loss sensor are made, located on same level of height and their dimensions are smaller than width of horizontal flow loss sensor blade, and they are made with displacement relatively to device body axis.

EFFECT: higher precision of measurements of acceleration of all productive layers along whole profile of well, possible determination of layers effectiveness for rational forming of underground storage and their effective operation.
