Development of water control technologies
The article presents ways to improve water inflow control technologies in production wells and repair and insulation works in injectors. These consist in cost reduction by eliminating the pre-lifting pump from the well. Such work on water shut control in producing wells is recommended to be carried out simultaneously with preparation for the current repair. An integrated technology including water shut off works, killing and acid stimulation of wells is offered. “IMR” is proposed as a plugging composition. The expediency of insulation works in injection wells to eliminate behind-casing flow using diverter technology is shown. It is recommended to temporarily isolate the productive layer by such compositions. The technology of temporary producing formation isolation with guar gel and other reagents is offered.
