The application is developed on the basis of conceptual methodological and algorithmic data and calculation optimization to perform the following functional assignment:
1. “Subdrilling” tasks complex
drilling mud drill collars package calculation;
drill-rod string package calculation under slide drilling for vertical columns;
drill-rod string package calculation under hydraulic rotary drilling for vertical columns;
hydraulic parameters and pump work modes calculation under subdrilling.
2. “Well casing” tasks complex
Casing strings calculation:
exploitation casing strings package calculation for oil wells;
intermediate casing strings package calculation for oil wells;
exploitation casing strings package calculation for gas wells;
intermediate casing strings package calculation for gas wells;
intermediate tail pipe calculation;
intermediate casing strings tripped in by parts calculation;
exploitation tail pipe calculation; o casing strings tension calculation;
o tolerated casing strings interior pressure calculation;
3. Casing string cementing calculation:
single-stage well cementing calculation o double-stage well cementing calculation
Logical structure
Initial data of general type introduction is made by user directly before the beginning of engineering calculation.
Specific data is introduced before each particular calculation type or item. All introduced data is saved for the further usage/changing for the case of recalculation necessity. All data must be checked for correctness in the moment of introduction. Volume and type of introduced data is determined by engineering calculation algorithm and by list of needed project documents. Calculation process is divided into separate modules, carrying out different necessary under the boreholes development engineering calculation as follows:
1. Casing strings calculation.
2. Cementing.
3. Drill-rod string calculation.
4. Drilling process hydraulic program calculation.
