Embodiment Construction

[0022] 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 with reference to the accompanying drawings and specific embodiments.

[0023] Coiled tubing rupture failure simulation method, using the coiled tubing simulation system to simulate the coiled tubing rupture phenomenon, through the simulation system console and touch screen for processing operations, including the following steps:

[0024] S1: Stop the coiled tubing, roller brake, and injection head brake through the console, and stop the pump through the touch screen to judge whether the crack is on the chain, if so, go to S2, otherwise, go to S4;

[0025] S2: Use the touch screen to drive the oil pipe clamp at the drum, close the slip gate and half-sealed gate through the console, and lift the 3-5 tons to test the slip gate, and lower it to 1 ton to judge the single flow Whether the valve is effecti...

Abstract

The invention discloses a coiled tubing fracture fault simulation method. The method comprises the following steps of S1, stopping coiled tubing, braking a roller and an injection head and stopping apump; S2, if a fracture is on a chain, lifting the coiled tubing excessively by 3-5 tons to test a slips gate plate and then lowering the coiled tubing until the coiled tubing is excessively lifted byone ton so as to judge whether a check valve is effective or not; S3, if the check valve is effective, connecting the fractured coiled tubing, and slowly winding the coiled tubing to the roller, otherwise, locking a semi-sealing gate plate, the slips gate plate and a full-sealing gate plate; S4, if the fracture is not on the chain, if the slips gate plate and the semi-sealing gate plate are closed, closing a shearing plate, and judging the fracturing position of the coiled tubing; and S5, if the fracturing position is in a shaft, closing the full-sealing gate plate, and opening the semi-sealing gate plate and the slips gate plate, and if the fracturing position is in a blowout prevention box, opening the shearing gate plate, relieving the pressure between the semi-sealing gate plate and the blowout prevention box, and taking out the coiled tubing. The real construction condition is restored, the training effect is enhanced by hand-operated operation, and training personnel can quicklymaster the puncture emergency treatment process of the blowout prevention box.

Description

Technical field [0001] The invention relates to the field of coiled tubing simulation, in particular to a method for simulating a coiled tubing fracture fault. Background technique [0002] Operators who have just participated in oilfield work are relatively unfamiliar with the working environment and unskilled in operation. In order to prevent losses in the production process, they often organize training for novice operators to enhance their proficiency. However, due to working environment problems, the cost of using 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. Summary of the invention [0004] In order to solve the above problems, the present invention proposes a method for simulating a coiled tubing...
