PROGRAM FOR THE BOTTOM OF THE DRILL BIT CONTROLLED MOVEMENT ANAGEMENT SIMULATION THAT TAKING IN ACCOUNT NON-CONTROLLED FACTORS
At present time, the need for horizontal directional drilling substantially increased, but for large waste from the vertical, uneven rotation of the bottom hole assembly (BHA) is observed, which leads to uncontrolled BHA and drilling stop. In studies aimed on managing the drilling process, various methods of the movement control of the BHA along a given trajectory modeling are used. At the same time, these currently used methods do not allow to take full advantage of the opportunities of BHA. So, the purpose of this work is to develop a program that implements these requirements and assess its practical applicability. The computer program for managing the drilling process with an open architecture has been developed to illustrate the operational version of the main program interface with some important design functions and is suitable for modification in the case of more complicated tasks related to the features of drilling a well. Currently, the program allows you to evaluate the planned load on the hook, corresponding to a given feed force to the face, taking into account the friction of the drill string along the walls of the well. In addition, the structures incorporated in the program allow solving even more complex problems arising during the movement of bottom of the drill bit in real rock. The results obtained during the work of the program allow us to conclude that the mathematical and simulation models of the bottom of the drill bit movement are adequate for real drilling situations.
