胜利油田整装油藏高含水正韵律厚油层水平井挖潜技术研究

水平井技术是胜利整装油田特高含水期正韵律厚油层剩余油挖潜的一项有效技术。由于水平井在生产过程中受层内夹层、剩余油富集厚度、水平井生产参数等方面的影响,针对正韵律厚油层层内剩余油分布特征,应用数值模拟技术,研究了水平井开发技术政策界限。此研究结果在整装正韵律厚油层的应用取得了较好效果。

Technique of tagging latent power of thick oil layer of positive rhythm with high-content water cut in self- contained pool in Shengli oilfield

The technique of horizontal well is an effective means to exploit the residual oil within the thick oil layer of positive rhythm with high-content water cut in self- contained pool in Shengli oilfield.Because the production is influenced by interlayer,enrichment thickness ofresidual oil and producing parameter of horizontal well,base on residual oil distribution features,the numerical simulation technique is utilized to analyze the limit of development technique of horizontal well. The study shows that the technique achieves an excellent production effect in the thick oil layer in self-contained pool.
