Embodiment Construction

[0042] Referring now to Figure 1, there is shown an oil and / or natural gas production well perpendicular to the formation 2 and equipped with a data measuring device of the present invention.

[0043] The data measuring device includes a downhole storage container 3 in which a plurality of spherical induction devices 4 are stored.

[0044] The storage container 3 is equipped with an induction device release mechanism 5 which releases an induction device 4 when it is activated by a remote signal 6 transmitted through a wireless signal source (not shown), such as a seismic source on the ground 7 .

[0045] The storage container 3 is installed by a wire rope (not shown) that pulls the container 3 to the lower end 8 of the wellbore 1, or by a downhole trolley or robotic device (not shown) that moves the container to the lower end 8 of the wellbore 1.

[0046] The container 3 is then releasably secured near the lower end 8 of the shaft so that it can be replaced when empty or if m...

Abstract

A method and system are disclosed for measuring data in a fluid transportation conduit, such as a well for the production of oil and / or gas. The system employs one or more miniature sensing devices (4) which comprise sensing equipment that is contained in a preferably spherical nut-shell which has an outer width which is smaller than the internal width of the conduit. One or more sensing devices are released sequentially in the conduit and are induced to move in longitudinal direction through the conduit to measure data at desired intervals of time, without requiring a complex infrastructure.

Description

technical field [0001] The present invention relates to a method and apparatus for measuring data in a fluid transport conduit and to an induction arrangement forming part of such an apparatus. Background technique [0002] It is often desirable to measure actual data in a fluid transport pipeline, such as temperature, pressure and fluid velocity and / or composition. However, it is generally not practical or economically feasible to place a sensor on a pipeline to measure such data along the length of the pipeline over an extended period of time. In this case, so-called smart blocks are used to measure the data, but since these are pumped through the pipe, they are large pieces of equipment, spanning the width of the pipe, and therefore not suitable for real-time measurements in the fluid flowing through the pipe . Also, tethered sensor probes are used to measure data in the pipeline, but these probes have limited travel and require complex and expensive winding operations....
