The technology for production profile logging in horizontal wells by artificial lift
摘要
Abstract
As oilfield development advances toward refinement,the contradiction between the continuous rise in the proportion of horizontal wells and the lag in production profile monitoring technology has become increasingly prominent.At home,existing horizontal wells produced by artificial lift suffer from a severe lack of production dynamic monitoring data due to the absence of dedicated logging channels and supporting conveyance systems,directly affecting the precise understanding of reservoir dynamics and the optimization of development plans.To address this challenge,an integrated technology for production profile logging suitable for artificially lifted horizontal wells has been developed.A hollow sucker rod pump is employed to achieve the dual functions of lifting formation fluids and constructing a logging channel,solving the challenge of simultaneous fluid production and instrument conveyance.A rigid rod conveyance system with instrument delivery and signal transmission capabilities ensures efficient and precise instrument delivery and data transmission in the horizontal section.A downhole cable butting device is designed to assist in rod suspension,pushing,and cable butting.Field applications demonstrate that this technology ensures stable lifting,with a 100%instrument delivery,95.6%qualified logging data,and 89.2%accuracy rate in locating water-producing zones,representing 14.2%improvement over traditional methods.The successful development of this technology provides critical support for efficient oilfield development and dynamic adjustments.关键词
