发明名称 METHOD FOR DETERMINING FORMATION PARAMETERS DURING INSPECTION OF LOW-DEBIT NON-FLOWING WELLS
摘要 FIELD: oil-extractive industry, in particular, hydro-dynamic methods for inspecting wells, possible use for determining formation parameters during inspection of low-debit non-flowing wells using method of successive change of stationary conditions. ^ SUBSTANCE: in accordance to method, after standard processing of actual influx curve, on its basis, pressure tracking time graph is built. For known value of bed pressure straight line is drawn on graph, connecting point of known bed pressure to bending point, which matches time of appearance of filtration resistances during filtration of liquid. Along this line time is counted, standing for theoretically optimal formation inspection period during influx. Then on actual influx curve bending point is placed, determined from pressure tracking graph, connected to point of intersection of optimal bed inspection time during influx and bed pressure and hypothetical influx curve is produced. Resulting curve is processed in accordance to unstable filtration method while determining hydrodynamic parameters of bed - productiveness, hydro-conductivity, penetrability and skin-factor. ^ EFFECT: expanded functional capabilities of method due to possible determining of larger number of hydro-dynamic and filtration parameters. ^ 1 tbl, 1 ex, 3 dwg
