Title: Motion compensated blowout and lost circulation detection
IPC: E21B21/08
Filed: 1974-09-30
Abstract: 1453203 Boring earth etc OFFSHORE CO 30 Sept 1974 [4 Oct 1973 26 Sept 1974] 42453/74 Heading E1F A method of detecting the commencement of blowouts or loss of drilling fluid in a subaqueous well hole 6 connected through risers 9 with a floating vessel 4 includes the steps of detecting the rate of flow of the drilling fluid back to the mud system 24 aboard the vessel 4 and generating a signal proportional thereto, modifying this signal to compensate instantaneously for the change in the volume of the flow path of the drilling fluid caused by the heaving of the vessel 4, and comparing the modified signal with the rate of flow of the drilling fluid into the well hole. As described the rates of flow of the drilling fluid entering and leaving the well hole are measured by flow meters 31 and 30 respectively. To accommodate the heaving motion of the vessel 4 the riser 9 has a telescopic section 11 and the drilling rod 15 has a telescopic sub 20, the riser 9 being tensioned by cables 32 (only one shown) fixed at their ends to the vessel 4 and to the lower portion 13 of the riser 9 and passing over sheaves 36 attached to piston rods 35 extending from cylinders 34. The heaving motion of the vessel is measured by a transducer (not shown) operated by one of the piston rods 35 by means of arm 37, cable 38 and sheave 39. In a first embodiment the outputs of the flow meters 30 and 31 are subtracted to produce a signal which is then modified by the signal from the transducer to compensate for the change in volume of the flow path of the drilling fluid caused by the heaving motion of the vessel, and this modified signal is fed to a chart recorder. Under normal conditions this modified signal is zero, an increase in the signal indicating the commencement of a blowout and a decrease in the signal indicating a loss of drilling fluid. An alarm may be sounded if the modified signal exceeds preselected threshold limits. In a second embodiment the output of flowmeter 30 is modified by the signal from the transducer to compensate for the heaving of the vessel and this modified signal is fed to a chart recorder. If the drilling fluid flows into the well at a constant rate variations in the modified signal are sufficient to indicate the commencement of a blowout or loss of drilling fluid. Otherwise the output of flowmeter 31 is also fed to the chart recorder and the two tracings can be compared to detect any difference between them.
