为老油区开发找到新思路

Core Viewpoint - The implementation of the "strong injection and expansion wave" technology, which integrates flow field regulation and blockage adjustment, has led to significant improvements in oil extraction efficiency and cost reduction for Shengli Oilfield's Jibei Oil Management Area [1][2]. Group 1: Technology Implementation - The "strong injection and expansion wave" technology has achieved a 100% efficiency in oil displacement, resulting in a cost reduction of 2.23 million yuan [1]. - The management area has faced challenges in maintaining stable production due to high water content and poor liquid supply in aging oil fields, necessitating innovative approaches to oil extraction [1][2]. Group 2: Experimental Results - Initial experiments in the Qu9-斜91 and Qu9-313 well groups showed a slight decrease in liquid volume and dynamic liquid level, but a significant reduction in water content, indicating the effectiveness of the injection process [2]. - The daily oil production in the Qu9-馆三单元 increased from 112 tons at the end of the previous year to 137 tons currently, demonstrating the success of the new technology [2]. Group 3: Future Development - The management area plans to continue exploring new development strategies and analyze potential well groups to enhance oil extraction in aging fields [3].
