Research Progress and Development Suggestion of Stratified Acidizing Strings in Water Injection Wells of Shengli Oilfield

摘要: 分层酸化是胜利油田解决分注井纵向差异和堵塞的重要技术措施，分层酸化管柱是实施分层酸化工艺的重要载体。结合胜利油田油藏实际，分析了注水井分层酸化管柱技术需求，总结了该方面的研究现状。分析认为，已经形成的K344型、Y211/Y221型和Y341型等3种基本分层酸化管柱，可以满足胜利油田整装、断块、低渗透等油藏常规注水井的分层酸化需求；另外，研究的可替酸分层酸化管柱可实现酸洗功能，酸化–返排一体化管柱可实现酸化、高效返排功能，分层酸化分层注水一体化管柱可实现分层酸化、分层注水，重复酸化完井管柱可实现单层的重复酸化，这些分层酸化管柱都已大量应用，并取得了一定的现场效果。但相对于现场实际需求和日益迫切的降本增效要求，现有管柱还存在许多局限与不足，为此提出了不断优化完善分层酸化管柱、进一步研究多功能集成管柱、加强智能注水技术和智能管柱研究的发展建议。Abstract: Stratified acidification is an important technique to solve the problem of the heterogeneity along the borehole and the blockage in the injection wells in Shengli Oilfield, which can be implemented by means of stratified acidizing strings. The technical requirements for this technique were analyzed and its current research situation was summarized with the field practice of Shengli Oilfield. According to the analysis, the existing basic strings, namely the K344, Y211/Y221, and Y341 could meet the requirements of the stratified acidizing of common injection wells in integrated, fault-block, and low-permeability reservoirs in Shengli Oilfield. In addition, some specialized strings were developed to realize pickling (acid-replaceable stratified acidizing strings), integrated acidizing and efficient flowback (acidizing-flowback integrated strings), integrated stratified acidizing and separate water injection (stratified acidizing-separate injection integrated strings), as well as the re-acidizing of a single layer (re-acidizing completion strings). Although these techniques have been widely adopted in the field with satisfied results, they are still far from meeting all the field requirements and the demands for lower cost and higher efficiency. Regarding these shortcomings, some suggestions were put forward including continuous optimization of stratified acidizing strings, further research on multi-functional integrated strings, and deeper studies of intelligent injection techniques and smart strings.
