多底井开采技术目前在我国尚属探索阶段。为预测多底井开发效果，对超低渗透率、裂缝发育的克拉玛依小拐油田中二叠统夏子街级油藏，应用油藏数值模拟技术，对其开采指标进行了预测分析，得出了双底井开采在二年和五年后的累积产油量分别是在井的4．71倍和3．46倍的结论。经济评价结果认为，双底并开采在经济上是可行的，也为今后深入细致的研究其开采技术提供了参考依据。
Multi-well mining technology is still in our exploration stage. In order to predict the development effect of multi-well, the mining numerical simulation technique is applied to the Middle Permian Xiazi Street reservoir in the ultra-low permeability and fracture development of Kelamayi Xiaowu Oilfield, and its mining index is predicted and analyzed The cumulative production of double bottom wells after two and five years was 4.71 and 3.46 times the well, respectively. According to the results of economic evaluation, double bottom mining is economically feasible and provides a reference for further and detailed exploration of its mining technology in the future.
