摘要
国内外油气田的开发实践表明,水平井压裂可以压穿多套储层,增加单井控制储量,提高单井产量。研究表明,水平井产能随裂缝条数、长度和导流能力增加而增加,且不同油藏状况下存在最优值。减少井筒根部和端部的裂缝间距可以增加水平井产能。在水平井压裂方案设计时,应根据储层地质情况和水平井压裂施工工艺,并充分考虑裂缝参数对水平井产能的影响来进行优化设计。
The development and application of oil and gas fields both at home and abroad show that horizontal well can fracture many sets of reservoir beds,increasing the controlled reserves of a single well,and improving its production. Research shows that horizontal well productivity increases with the number,the length,as well as the flow conductivity of cracks. Reducing the distance between the wellbore and the end of the cracks can increase the productivity of horizontal well. The horizontal well fracturing program design should be based on the geological conditions of the reservoir and horizontal well fracturing process.
