Mathematical methods usage in the budgetary price setting question while well construction
A.GaralovThe following directions are run out while budgetary rate and price setting main objectives determination: *definition of construction standard cost; *planning, financing and carrying out the calculation for covered amount of construction- assembly works; *assessment of construction-assembly organization activity. The basis of construction right and objective assessment - assembly organization activity is certainty of budgetary rates in particular unique regional unit prices (URUP) by which construction budgetary cost is determined. In order to determine the well construction budgetary cost under offshore and onshore compilation 48 and compilation 49 have been used, correspondingly. The comparative analysis of offshore and onshore quotation of «Denomination of materials and reserve parts consumed in the drilling and power equipment operation process» is shown in the article. As a result of analysis it is found that assessments for offshore conditions are lower for several times than the assessments used for onshore construction. They are not divided into drilling aims-exploratory or prospecting drilling and the drilling intervals decreased for two times. The rate scale of material cost for offshore conditions are recalculated for definite intervals, grapho-analytical method is applied and the curves of unit price dependence on well depth are plotted. Using the proposed method of calculation, distortions is eliminated and the statement of materials and reserve parts values used in the process of drilling and power equipment operation is brought into compliance. Proposed grapho-analytical method allows to determine the material cost for well any depth that provides improving accuracy while budgetary cost determination and to carry out the analysis of actual material rate in well construction.
