转向重复压裂技术在陕北低渗透油田的应用
|
摘要
在转向重复压裂技术原理及进展的基础上,分析了常规压裂与转向重复压裂的共性与差异,给出了转向重复压裂井层优选原则,提出了新生裂缝长度及新增渗流面积的估算方法。该转向重复压裂工艺技术在陕北低渗透油田进行了现场应用,并取得了好的应用效果。
Based on reviewing the principle,performance and mechanism of the turnaround refracture technology,according to the advantages and disadvantages of the current conventional fracturing and turnaround refracture technology, the similarities and differences of the current conventional fracturing and turnaround refracture technology were analyzed, wells selective and layers selective principles and optimization designing of operation parameters of turnaround fracture technology were formed,which produced significant effects in lower permeability oil fields.This paper also proposed the methods of estimating fracture length and the seepage area of the turnaround refracture and achieved good results through the on-site applications for the low permeability oil fields in northern Shaanxi,which greatly increased the production.It may provide guidance for the transformation of the old wells in similar reservoirs.
