吞吐注汽时吸汽层段的位置取决于注汽尾管的下入深度,而产液层段又取决于吸汽层段,即取决于注汽尾管下入深度,注汽尾管所在油层段为主要动用层段.每轮注汽吞吐时,主要动用层段的厚度是有限的,其上限值一般为10m,而且厚度不随时间的延长而上下移动和扩大,可通过改变注汽尾管下入深度来改善油层动用状况,提高吞吐效果.克拉玛依油田九区用该方法取得了每井轮次增产26.9%的好效果.
The location of the suction section when the steam is injected is determined by the depth of the injection tail pipe, which in turn depends on the suction section, that is, the depth of the injection tail pipe, the depth of the injection pipe tail pipe The reservoir section is the main section to be used, and the thickness of the main section is limited when the injection steam is exhausted by each round, the upper limit is generally 10m, and the thickness does not move upwards and downwards with the extension of time, Liner depth into the reservoir to improve the utilization of the reservoir to improve the throughput.Kalamay Oilfield nine districts by this method has achieved a yield of 26.9% per well well.
