Abstract

The invention discloses a testing device and method for testing the push-pull force and torque of the horizontal section of continuous tubing, which comprises the following steps: step 1: simulate the drilling process; step 2: simulate the lifting process; The present invention can detect and collect the mechanical parameters of the coiled tubing test piece in the experimental process of coiled tubing drilling, grinding, fishing, etc. in real time, and make real-time adjustments compared with the actual wellhead parameters, effectively guide the on-site construction, improve the operation efficiency of the coiled tubing, and reduce the sticking of the coiled tubing, etc. risk.

Description

technical field [0001] The invention belongs to the field of downhole operation experiments such as coiled tubing drilling, grinding, fishing, etc., in particular to a detection device and method for testing the push-pull force and torque of the horizontal section of the coiled tubing used in experiments. Background technique [0002] At present, in downhole drilling, grinding, fishing and other operations, coiled tubing is used more and more. Considering factors such as coiled tubing flexibility and wellbore structure, it is currently impossible to accurately detect the mechanical characteristics of coiled tubing specimens in horizontal well sections, and thus cannot Provide quantitative benchmarks of construction parameters for on-site operations, causing unnecessary downhole accidents. [0003] According to the survey, domestic coiled tubing technology research methods are relatively deficient, especially a targeted real-time testing method for coiled tubing test pieces f...
