    摘要： An electric pump including a linear motor (34) consisting of a stator (40) and a moving element (42) driven by the electromagnetic field generated by the stator, and a pump piston driven by the linear motor, is disclosed. The piston (42) is arranged inside the stator (40) of the electric pump and forms the moving element of the linear motor. An oil well facility provided with such an electric pump is also disclosed.

    摘要： An oxidation unit (2a) is used which comprises, in series, three catalytic stages (3a, 4a, 5a) each containing a catalyst for promoting the selective oxidation of H2S to sulphur up to a temperature υs ≤ 150 °C. The gas to be processed (16) is fed through each of said stages and air (50, 53a, 55a) is injected into each stage. An H2S fraction of said gas is adiabatically oxidised to sulphur in each of the first two stages (3a, 4a) with an amount of air such that a temperature no higher than υs is achieved at the outlet of said stages. All the H2S in the gas fed into the final stage (5a) is oxidised in a controlled excess of air at temperatures no higher than υs. The method is useful for processing H2S-containing gases produced by the hydrogenation/hydrolysis of sulphur plant waste gases.

    摘要： An instant acoustic logging method for use in oil drilling, wherein a drill bit (16) arranged at one end of a drill string (12) and rotated in a well (18) is used as the acoustic source. The method comprises the steps of measuring, at the top (22) of the string (12), the vibration generated therein by the rotating drill bit (16), sensing acoustic signals from the drill bit (16) at at least one point (24, 26) on the ground (28) away from said drill bit (16), and processing the signals to provide data on the rock (32, 34, 36) around the well (18). Said method comprises an additional preliminary step of processing the vibration measured at the top (22) of the string (12) to determine the nature of the pilot signals from the drill bit (16), said data on the rock around the well being obtained by comparing the acoustic signals sensed on the ground (28) with the pilot signals from the drill bit (16).
