W103-9LS 井是我国某海域的一口海上采油井,采用天然能力开采,停喷后通过同井注气采油(单井吞吐),取得一定效果。本井位于断块油田的“巷道”之中,控制面积较小,但油层仍有一定的厚度:油层砂岩直厚度26m,有效直厚度21m,含3个小层,分4个射孔段。单层最大厚度为:砂岩直厚度11.3m,有效直厚度11.3m。原始地层压力22.3MPa,饱和压力20.3MPa,原始油气比125m~3/m~3,地层原油粘度0.5364mPa·s。
Well W103-9LS is an offshore oil well in a certain sea area of China. It is exploited with natural ability and controlled by gas injection (same well stimulation) after stopping gas injection, and achieved some results. The well is located in the “roadway” of the fault block oilfield and has a small control area. However, the oil layer still has a certain thickness. The reservoir sandstone has a straight thickness of 26m and an effective straight thickness of 21m. It contains three small layers of four perforation sections. The maximum thickness of a single layer is: sandstone straight thickness 11.3m, effective straight thickness 11.3m. The original formation pressure is 22.3MPa, the saturation pressure is 20.3MPa, the original oil-gas ratio is 125m ~ 3 / m ~ 3, and the formation viscosity is 0.5364mPa · s.
