摘要：

为进一步提高孤岛油田稠油环储量动用程度和蒸汽吞吐采收率，通过应用水平井与直井联合优化布井等方式对区块进行了开发调整；通过数值模拟技术，对热采水平井在油层中的位置、水平段长度、延伸方向及吞吐注采等参数进行了系统研究。方案实施后，水平井开采取得了显著效果，平均单井日产油达到57.4t，是周围同期投产直井的4倍，含水率稳定在20.0%左右，比直井的低15％～30％。该技术对于在稠油油藏中应用水平井进行蒸汽吞吐挖潜、提高采收率有较大的参考意义。

Abstract:

In order to improve reservoir exploitation degree and recovery of heavy oil loop in the Gudao oilfield, the exploitation project was adjusted according to optimizing well planning with data of horizontal well and vertical well, and the place in oil layer, length, stretch orientation and injection-production parameters were studied systematically by numerical simulation.With the implementation of this program, good results were gained, for example, the product of single well was about 57.4t/d, which was 4 times as much that of around vertical wells; and water cut  stays about 20% , which was 15%-30% less than that of vertical well. Therefore, this technology was important for tapping potential and improving recovery with horizontal well.

Key words: heavy oil loop, horizontal well, cyclic steam stimulation, development adjustment, Gudao oilfield
