复合压裂技术在长庆油田致密油藏中的应用磁
Application of Compound Fracturing Technology to Tight Reservoir in Changqing Oilfield
摘要
Abstract
Based on the low porosity and low permeability of tight reservoir ,and on the test results and analysis of fracturing damage mecha-nism of fracturing fluid ,a composite fracturing technology is put forward ,in which active water and glue are used to replace the linear pre-pad fluid and crosslinked guar gum at the stage of low sand ratio .On the premise of ensuring the sand -carrying performance ,the amount of guar gum fracturing fluid used is reduced ,alleviating the damage of fracturing fluid residue to the reservoir .This technology application in tight oil reservoirs in Changqing Oilfield achieves good results .关键词
