Subject: исследование скважин_3 Господа, хелп ми, плиз.....Уровень раствора в скважине в процессе опробования не изменился. Движения воздуха из труб не наблюдалось. |
During the test, we recorded no fluid level changes and no air flow out of pipes. The rated drawdown was 200 ksf/cm3, the pipes were filled with technical water. While RIH, 20 pipe stands were left empty. Actually, after testing the well, 20 empty pipe stands were POOH, i.e. the anticipated drawdown was not lowered by spontaneous ИПГ opening while RIH. Pipe pressure would be 336 kgf/cm2, but it was 517 kgf/cm2 as measured by downhole gauge MSU-2-600 No.6725 (?). The gauge chart (diagram) clearly shows the moment of ИПГ opening and ИПГ closing. Total downhole measurement time was 4 hrs. The gauge downhole measurements are displayed as a horizontal line. Pressure build-up, a characteristic of typical PBC, was not recorded. We suspect that ЗПК was not closed and the entire 4-hrs time was the time of flowing well operation. The final decision will be made upon ЗПК check dismantling. If the rod/pin is slill in the open position, that means we spent 4 hrs for recording an inflow; if the ЗПК rod/pin in the up position and ЗПК is closed, the strait line indicates that the target interval is made up of tight rocks .... |
