Description
Technical Field
The utility model relates to a monitoring system and method of oil industry coiled tubing well drilling, especially coiled tubing well drilling power drill's control analog system.
Background
Shallow drilling and old well side drilling by using coiled tubing equipment are an emerging petroleum drilling technology. The coiled tubing is thin in pipe diameter and can be coiled in a roller on the ground, the coiled tubing is put into a well through the roller, drilling mud of the coiled tubing passes through a mud joint in the roller, one end of the drilling mud is connected with the tail end of the coiled tubing, the other end of the drilling mud is connected with a mud pump, and the drilling mud forms circulation with a mud pool. Because the coiled tubing is thin in pipe diameter and easy to bend when being blocked, the coiled tubing is more obviously deformed particularly when drilling. However, the coiled tubing has the advantage of continuity that a single drill rod does not need to be replaced midway, so that the drilling speed is higher, the drilling period is short, and the drilling cost is greatly reduced. At present, the technology of shallow drilling and old well sidetracking by using coiled tubing in China is just started, some key technologies are still in an exploration phase, and particularly, a ground drilling control device or system of a coiled tubing drilling power drill bit is more key technical equipment for shallow drilling and sidetracking.
In the drilling footage construction, under the influence of different geological mud layers, rock stratum structures and the like in the ground, the drilling track of the coiled tubing is controlled on the ground, sometimes, a drill bit does not even drill a drilling target layer, sometimes, the actual drilling footage is much more than the budget, and in the cluster well group, the drilling target layer is drilled. In order to better understand the drilling trajectory of coiled tubing downhole, devices have been patented, such as: the coiled tubing drilling power bit control device and the method of using the same are filed with the application number 201910852694.4.

At present, no relevant research and report exists, namely how to simulate and verify the actual drilling position of a downhole drill bit controlled by a coiled tubing drilling ground control system and judge the drilling conforming condition or conforming rate with a preset design position, which cannot be realized at present.
At present, the general verification method is to monitor the drilling track in time by using the existing wireless while-drilling system technology in normal construction, and then adjust the drilling track in time through the observation of a simulation image. In the method of the above-mentioned type,
drilling mud is used as a medium to transmit through mud waves, and the transmission rate is very low, generally a few b/min and a few bytes per minute. After the instruction of the wireless ground control device while drilling is sent out, for the construction of a drill bit for high-speed drilling, the instruction cannot be transmitted in time, and the disorder change of a drilling track can be caused by serious delay. The construction is complicated, the drilling cost is increased, the construction period is prolonged, and other negative effects are caused.
In order to change the current situation that the drilling track of the drill bit controlled by the current coiled tubing ground control system and the coiled tubing drilling power drill bit control device cannot be determined to be consistent, a control simulation system of the coiled tubing drilling power drill bit needs to be developed so as to improve the current situation, improve the drilling quality of the coiled tubing and reduce the drilling cost.
