Application of four-dimensional seismic technique in heavy oil exploitation
The response of seismic information to reservoir suffered steam thermal field is mainly judged from the variation of corresponding reflection waves amplitude, interval velocity, and delay time. The area where amplitude, interval velocity and delay time have apparent variance is where steam thermal front can arrive. Oppositely, the area is not in steam thermal fields influence area. We call it distributed area of remaining oil. Remaining oil of 95159 well field in district nine five exist in three areas: area between 95159 well with 95178 well, the south to 95140 well, the north to the 95197 well. Basing on the study of remaining oil distribution regulation, and incorporating with dynamic monitoring data and production performance, the steam drive is adjusted, plane infilled, plugged and corrected. It takes lrominence effects: in district six and nine, annual oil comprehensive decrease progressively of steam drive decreased to 1.1 percent in 2004 from 5.5 percent in 1955; oil gas ratio raised to 0.2 from 0.12 in 1995, and the steam drive stable produced in continual nine years
