Abstract
1438105 Determination of proportions of phases in a multi-phase fluid SCHLUMBERGER INLAND SERVICES Inc 5 Sept 1973 [6 Sept 1972] 42019/72 Heading G1B Apparatus for determining the volumetric proportions of the phases of a multi-phase fluid flowing in a production well comprises elongated body member 18 for suspension in the well, the body member having a portion 20 of reduced cross section, sleeve member 21 slidably mounted on the body member and movable between a first position in which it co-operates with portion 20 of the body member to define an enclosed sampling chamber (72), Fig. 2, (not shown) and a second position as shown in which the chamber is open, actuating means 27, 26, 33, 36, 37, 42 for moving the sleeve member 21 between the first and second positions, a sample of the well fluid being trapped in the sampling chamber when the sleeve is in its first position and allowed to settle into its constituent phases, sensing means 68 for producing output signals representative of a characteristic of each phase, for example its density, and displacement means for producing relative movement between the sensing means and successive portions of the separated fluid. In the apparatus shown, the sleeve member is longitudinally movable by operation of motor 26 rotating lead screw 30 causing travel of nut 33 carrying sleeve 21. Nut 33 also carries rods 36 and spring-loaded piston 37. For movement of the sleeve member 21 and piston member 37 to their upper (second position), latch member 40 engages a groove 43 in the sleeve member. An indentation 45 on portion 20 co-operates with a cam surface on the latch member to release the latch from the sleeve member to allow downward travel of the sleeve member alone under the action of spring 49, when the sample chamber formed between the sleeve member and portion 20 traps a sample of the fluid. Motor 26 then moves nut 33 and piston 37 downwardly to force the sample through passage 64 and chamber 63 past sensing means 68 and back to the well past valve 67. In another embodiment, chamber 63 is omitted and a density sensing means is mounted on the underside of piston 37. This sensing means may have exposed electrical connections so that its short-circuiting indicates its entry into the water phase.
