针对辽河油田直井注蒸汽开采超稠油油藏效果差的实际情况，利用最新研制的水平井热采数值模拟软件———ＮＵＭＳＩＰ－４软件，研究了杜８４块不同水平井布井方式和开采方式的开发效果。结果表明，该块最佳开采方式为蒸汽辅助重力驱，并采用成对水平井组合，上注下采，水平段长３００ｍ，注采井距１５ｍ的布井方式。该项研究成果可以为类似超稠油油藏的开发所借鉴。
In view of the actual situation of the ineffectiveness of vertical well steam injection in extra-heavy oil reservoirs in Liaohe Oilfield, NUMSIP-4 numerical simulation software for horizontal well thermal recovery was used to study the well drilling and mining methods of different horizontal wells in Du 84 block Way of development effect. The results show that the optimal mining method for this block is steam-assisted gravitational flooding, and the wells are grouped by paired horizontal wells, injected and withdrawn with a horizontal section length of 300m and a well spacing of 15m between injection and production wells. The research results can be drawn from the development of similar ultra-heavy oil reservoirs.
