Embodiment Construction
[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] Various working conditions can be realized by adjusting the configuration of the coiled tubing simulation system, and setting the blowout box puncture failure parameters to make the system simulate the blowout box puncture phenomenon. The coiled tubing simulation system is equipped with a console and a touch screen to adjust graphics and parameters. The console realizes simple control and adjustment of the operating equipment, and the touch screen is used to simulate manual operation of the operating equipment.
[0033] Such as figure 1 As shown, the coiled tubing crack failure simulation method uses the coiled tubing simulation system to simulate the coiled tubing crack phenomenon, and performs processing operatio...

The invention discloses a coiled tubing crack fault simulation method. The method comprises the following steps: S1, stopping a coiled tubing, a roller brake and an injection head brake through a console; S2, evaluating a leakage state; s3, stopping a pump through a touch screen, and releasing the pressure of the coiled tubing; S4, judging whether a check valve is effective or not; if so, turningto S5; if not, turning to S6; S5, slowly pulling out the coiled tubing through the console; S6, judging whether leakage continues or not; if so, turning to S7; if not, ending the operation; S7, judging whether the coiled tubing is seriously damaged or not, if yes, turning to S8, and if not, turning to S9; S8, closing a fully-sealed flashboard blowout preventer through the console; and S9, loweringthe leakage point to the position between a blowout prevention box and the semi-closed flashboard through the console, and closing a slip flashboard and the semi-closed flashboard. The method can reproduce actual construction conditions. The invention further provides a processing method; through manual operation, the training effect is enhanced, and trainees can quickly master the blowout prevention box puncture leakage emergency processing flow.
Description
technical field [0001] The invention relates to the field of coiled tubing simulation, in particular to a method for simulating faults of coiled tubing breaches. Background technique [0002] The operators who have just participated in the oilfield work are relatively unfamiliar with the working environment and unskilled in operating techniques. In order to prevent losses in the production process, they often organize training for novice operators to enhance their proficiency. However, due to the working environment, the cost of production equipment for training is too high, so the training content is limited to written training, and the actual training effect is not strong. [0003] The coiled tubing simulation system uses computer simulation technology, computer graphics technology and virtual reality technology to simulate coiled tubing operations. Contents of the invention [0004] In order to solve the above problems, the present invention proposes a coiled tubing br...
