东胜公司打造“少井高产、大幅提产”样板

Core Insights - The successful production of the Zhan29-Ce Ping43 well by Dongsheng Company demonstrates the effectiveness of integrated side-drilling technology, achieving a stable daily oil output of 10.3 tons with a water cut of only 33% [1] - The implementation of this technology has led to a 46% increase in average daily oil production per well in the Taiping Oilfield, providing a model for efficient development of similar oil reservoirs [1][2] Group 1 - The Zhan29 block, a mature high-permeability heavy oil reservoir, has faced challenges due to high water cut and poor well efficiency for over 25 years [1] - Dongsheng Company's technical team utilized detailed geological studies and modeling of remaining oil distribution to identify core areas for further development [1] - In 2024, the company plans to conduct "significant production enhancement tests" on two new wells, Zhan29-Ping35 and Zhan29-Ping36, which have shown promising initial results with an average daily output of 15.8 tons [1] Group 2 - The new integrated side-drilling production model focuses on precise drilling, efficient completion, and full-layer protection, enhancing communication and decision-making during the drilling process [2] - This model has resulted in an 81% increase in production capacity compared to pre-modification levels, with average daily oil output stabilizing at 10 tons for the newly drilled wells [2] - Dongsheng Company has established a replicable development framework combining detailed geological research, advanced technology, and comprehensive oil layer protection for efficient exploitation of heavy oil reservoirs [2]
