杜84块水平井开采数值模拟研究

Numerical Simulation Study on the Horizontal welled Mining of the Du-84 Block

针对辽河油田超稠油油藏注蒸汽开采效果差的实际情况，利用数值模拟方法研究杜８４块水平井开发效果。结果表明，该块最佳开采方式为蒸汽辅助重力泄油，布井方式为成对水平井组合，上注下采，水平段长３００ｍ，注采井距１５ｍ。

To counter the real situation of bad effect in the mining of the extra thick oil of Liaohe Oil Field by the steam charging method,the author studed the mining effect of the horizontal well of Du-84 block by the method of numerical simulation and indicated that the best mining method for this block is Steam supplementary gravity oil discharging,the well distribution should be the combination of doubled wells steam is charged into upper part the oil is extracted from lower part the horizontal well section is 300m and the charging well interval is 15m
