摘要
中原油田油气藏具有油层非均质性严重,生产井段长,主力油层含水高,Ⅱ、Ⅲ类储层动用程度低等特点。针对常规分层压裂技术针对性不强、改造不彻底的状况,通过分层压裂工具研制、管柱优化,实现一趟管柱任意层段压裂,提升了分层压裂技术水平,从而提高Ⅱ、Ⅲ类储层动用程度。这项技术适应了油藏开发后期精细注采调整需要,为油田精细开发提供了有力的技术支撑。
Reservoirs with strong heterogeneity in zhongyuan oilfield,the main production layers of which have enterd high water cut stage,but the non-main production layers have the low producing degree,have increased quickly in recent years.Based on the Conventional hierarchical fracturing,we have studied and manufactured stratified tools and optimized fracturing string.This technology enhancing the Pertinence of the develop of the non-main production layers realizes arbitrary layers fracturing,and improves the level of hierarchical fracturing,This technology accommodates the fine development of reservoirs in the mid-late stage.
