摘要:
A sample of fluid such as a gaseous fluid leaving a liquid/gas separator in a surface installation of an oil well, is taken continuously via a sampling tube. The tube opens out on the axis of a gas outlet pipe, facing towards the separator receptacle and located at the junction between the pipe and the receptacle. Sampling is performed isokinetically by regulating the flow rate in the tube by means of a regulator valve controlled by a regulator as a function of flow rates measured in the tube and in the pipe. In the tube, liquid is separated from the gas by means of a filter.
摘要:
A multizone testing system (100), for the testing of subterranean layers, comprises an upper subsystem (109) comprising a control station (151), a main isolation packer (113) for isolating the upper subsystem (109) from the lower subsystem (111), a lower subsystem (111) comprising an array of individual apparatuses (116) connected in series, each apparatus (116) being adapted for the testing of one layer and comprising a series of remotely activated tools for hydraulically isolating and testing the corresponding layer and a communication system comprises communication means between the control station (151) and the surface and between the control station (151) and each of the individual apparatuses (116) in order to control the remotely activated tools of the individual apparatuses for sequential testing of the layers. A multizone testing method for the testing of a plurality of subterranean layers intersected by a well, using a multizone testing system (100) comprises the steps of running and positioning said system (100) into the well such that each individual apparatus (116) is adjacent to a layer to be tested and controlling the remotely activated tools of the individual apparatuses for a sequential test of the layers.
