MATHEMATICAL SIMULATION AND COMPUTER IMPLEMENTATION OF TECHNOLOGICAL ASPECTS OF THE PROCESS OF THE HYDRODYNAMICAL FORMATION INVESTIGATIONS WITH THE APPLICATION OF DRILL-STEM TESTERS
Technological aspects of formation testing with drillstem formation testers have been considered. A simulation of the technological process of well investigations with the help of drill-stem formation testers (lowering the tester into the well, recording the inflow and pressure build-up curves, correction for the characteristics of hydrobraking relay, and so on) has been validated and developed. The simulation can become a tool for conducting and planning the technological operations in the well, enhance the effect of the drill-stem formation testing.
