The article is devoted to the development of methods for processing initial data about the drilling object and the capabilities of technical means, allowing for a fairly reliable simulation of the actual drilling process in its capabilities, evaluation of the integrated geological and economic indicators of its effectiveness, and on this basis the choice of rational technical and technological solutions, which were considered the following characteristics: cost parameters of drilling, drillability category, depth, well angle, current well coordinates thickness of rocks, forming the section, intensity of natural curvature of the well in them, point of subsection of the ore body. The implementation of the technique was carried out by the method of simulation, in the course of which possible options were determined; the calculation of each development option was made and a comparative analysis of technical and technological costs for drilling wells was performed. An algorithm for making technical and technological decisions was proposed, according to the multi-variant passage of the borehole. On the basis of this, the choice of the optimal drilling option is made, carried out by subjective consideration of possible consequences.
The proposed algorithm contains the following blocks: a block for entering data about the initial uncertainty of an object and possibilities of technical variation; block forming an array of possible options for the implementation of the object; block forming an array of possible technical and technological solutions; a unit for determining the likelihood of a particular object implementation block definition requirements for drilling results; unit for determining the characteristics of the forms of drilling results; the unit for determining the compliance of the characteristics of the material forms of the result with the conditional requirements; block of calculation of additional costs for the elimination of a technological defect of a certain type; block calculation of the direct costs of the implementation of technical and technological solutions
The use of simulation techniques allows theauthors to make specific technical and technological solutions in the conditions of uncertainty of the real object.
