THE STUDY ON THE CONTINUITY OF THE RESERVOIRS OF SHALLOW ZONE IN QINGHAI HUATUGOU OIL FIELD
青海花土沟油田浅层油藏连通性研究

It is importan to analyze the continuity of fluids in reservoirs in developemnt geology. The condition of the continuity of reservoirs is relate to not only the location of production well and the perforated interval but also the location of input well and the efficiency of injection of water. The techniques of the fignerprints of gas chromatograms and spectrophotometry have been applied to the vertical and lateral continuity of the reservoirs. The industrial scale oil was found by penetrating at shallow zone (305 m) in well S1-26-1. The result of testing once at shallow zone suggested that there was merely oil trace, not industrial scale oil. So it is doubted that the industrial scale oil come from the mid-deep level because of the leaky casings. The results of study on the continuity of oil between well S1-26-1 and near this well show that the oil of well S1-26-1 come from the shallow zone.
