发明名称 OILFIELD OPERATION USING A DRILL STRING
摘要 Collecting temperature data at a plurality of locations along a wellbore, performing thermo- mechanical simulations of a drill string in response to mud circulation wherein the drill string comprises a tool string suspended in the wellbore from a pipe string, determining changes in length of the pipe string due to temperature changes, positionally fixing the tool string at one of the locations, and adjusting the length of the pipe string based on the determined change in length of the pipe string. Positionally fixing the tool string may comprise lowering the drill string a side entry sub of the drill string is proximate a top end of the wellbore wherein the side entry sub is configured to allow a wireline cable to enter a bore of the drill string, positioning the side entry sub above a blow-out-preventer, and closing the blow-out-preventer around the drill string below the side entry sub.
