多组合找漏找窜测井技术在河南油田的应用
|
摘要
针对河南油田开发后期出现的套管漏失、管外窜槽等影响水井有效注水或油井正常生产的井下技术状况复杂问题,在分析单一油水井找漏找窜技术缺陷的基础上,提出了采用提取地层和井况信息多、测量范围大、精度高、工艺环保的井温、流量、示踪剂和氧活化水流等多组合找漏找窜测井技术。实际应用表明,该测井技术可准确评价判断油水井套管漏失或管外窜槽情况,为不正常注水井、采油井有效治理提供了科学依据,并在河南油田稀油油藏中被广泛应用,取得了较好的效果。
Aiming at the problems at the late development of Henan oilfield, such as the casing leakage and channeling outside the tube, which affected the effective injection of water wells or the normal production of oil wells, based on the shortcoming analysis of leakage and channeling detection by single oil well or single water well, a multi-combination leakage and channeling detection technique was proposed. The practical application shows that the logging technology can accurately evaluate the casing loss of oil and water well or the situation of channeling outside the tube, which will provide a scientific basis for the effective treatment of abnormal injection wells and production wells, and it has been widely used in thin oil reservoirs of Henan oilfield and achieved good results.
