刘庄白庙地区压裂改造配套技术研究

中原油田刘庄、白庙地区构造复杂，储层埋藏深，物性差，油气水层电性特征不明显，气藏类型复杂，试采井生产压差大，自然产能低，反凝析现象严重，加之地层高温高压，开采难度较大。针对这一现象开展了压裂综合技术研究，通过分析影响该地区压裂效果的因素，研究出一套压裂改造配套技术，并通过实例证实了该配套技术的可行性。

Blocking Technique of Retrievable Bridge Plugs

Oil production is rather difficult in liuZhuang and Baimiao block of Zhongyuan oilfield because of the fact including complex structure, the deep pay zone, bad physical property, unclearly electric behavior between water and oil, complex pattern of gas reservoir, furthermore, low natural productive energy, low draw down pressure difference, serious retrograde condensate, high temperature and high pressure formation. As for this phenomenon, the fracturing stimulation technology was further studied. By analyzing factors affecting fracturing effects in this territory, a new recasting technology of fracturing stimulation was developed and its viability had been testified by examples.
