易解卡式分层压裂技术在泌阳凹陷的应用

The Application of Releasing Zoning Fracturing Techniques in Biyang Depression

根据EW37井的地质概况、试油参数和压裂前后产能变化，研究分析了易解卡分层压裂技术的施工特点、压裂原理和压裂效果，并在EW37井进行了应用。结果表明，易解卡分层压裂可实现在分层压裂的同时各层压裂效果良好，该项压裂技术在应用实践中取得了明显的增产效果。

Based on geologic situation,formation test parameters and productivity changes both before and after reservoir fracturing in Well EW37,the operation characters,fracturing principles and its effect of the releasing fracturing technique were analyzed and the technique was used in Well EW37.The result indicates that it can be used for zoning fracturing with good effect,it is obviously used for enhancing oil recovery.
