套损井综合管理系统的开发及应用

目前大庆油田年套损井数达到1000口左右，严重破坏了油田的注采平衡关系，而且制约了油田注采结构的进一步调整。根据大庆油田套损特点，套损状况及油田生产实际，开发了套损井综合管理系统，包括套损数据管理，大修数据管理，井况调查数据管理和报废数据管理四大模块，套损机理研究认为，泥岩蠕变是大庆杏树岗油田管损坏的主要原因。应用油水井大修工艺措施合理优化与组合经济评价数学模型，可以实现大修工艺措施合理优化与组合；应用套损井综合管理数据库，实现了套损井计算机网络管理。套损井综合管理系统推广应用后，经济效益和社会效益显著。图2表1参3（王永东摘）。

Development and application of integrated management system for casing damage well

At present, there are over 1000 casing damage wells in Daqing oil field. Casing damage not only destroys seriously injection-production balance of oil field, but also restricts further adjustment of injection-production structure of oil field. In the paper, at first according to the casing damage features of Daqing oil field, casing damage conditions and production practice, we clarify the necessary and importance of developing an integrated management system for casing damage well. Then composition and function of integrated management system for casing damage well are introduced, and we describe in detail the mathematic model of economic evaluation which can optimize and combine big repair technical measure for casing damage wells. Taking Xingshugang oil field in Daqing oil field as example, using mudstone creep theory and Mesais rule, casing damage mechanism of Xingshugang oil field is determined. In the end, the popularization and application results of integrated management system for casing damage well are introduced. Successful development of integrated management system for casing damage wells provides a theoretical basis for engineering technical staffs to analyze the cause of formation for casing damage and work out an economic and reasonable integrated treatment project, improve work efficiency of casing damage well management, gain better economic and social benefits.
