摘要： A sand control device for restricting flow of particles from a subsurface formation into a tubular body within a wellbore, the device being divided into compartments along its length, each compartment comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment, also comprising a first filtering conduit and a second filtering conduit. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe.

摘要： A system and method for initializing and calibrating a fiber optic pressure transducer so that a measured intensity of light which varies as a function of pressure can be accurately translated to the value of pressure which produces that value of light intensity. The transducer includes an enclosed sensor tip having a diaphragm which is exposed to atmospheric pressure on the inside and the pressure to be determined on the outside as measurements are taken, the resulting pressure differential producing a related attenuation in light intensity. Calibration according to the present invention is performed by exposing the diaphragm to atmospheric pressure on the outside and sub-atmospheric pressure on the inside while transmitting light through the fiber in the usual manner. The sub-atmospheric pressure is changed gradually as simultaneous measurements are made of the intensity of light returned through the fiber and the actual value of the sub-atmospheric pressure at a number of discrete times. The paired values are stored in a look-up table which is subsequently used to determine unknown pressures from matched values of measured light intensity.
