Chinese oil network news from August 25th, Shuguang oil production plant of Liaohe Oilfield good news, the implementation of improved symptomatic chemical water plugging measures, shutting down nearly a year of Shu 1-43-655 wells water content decreased by 40 percentage points, the highest Nissan 11.4 tons, 8 consecutive days to maintain production in more than 10 tons. 　　Since the beginning of this year, the research process of Liaohe Oilfield Shuguang by pressure water cone effect of nitrogen in water in oil well, the first plug, the original gel plugging agent for nitrogen foam gel plugging agent has a good effect on the test measures in shut down wells. 　　Qianshan is located in the heavy oil reservoir of Shu1 area Shu 1-43-655 wells, water sufficient, high angle cracks. For this well water effective governance, Shu mining project technology research institute group in the thirteenth round of steam injection wells before the implementation of improved chemical water plugging. Because the formation water invasion of this well is large and the water coning radius is large, the conventional water plugging method can not achieve the desired effect. Therefore, a new method of chemical plugging process with large dose is decided. 　　Based on the preceding Shu 1-43-655 wells and water injection foam gel plugging agent, which containing starch granules, and pumped into the far wellbore, to enhance the strength of plugging plugging agent. The latter uses high temperature plugging agent sealing, not only can fill the near well zone with large cracks and pores, but also can effectively reduce the steam to foam gel plugging agent damage. The two plug plays a synergistic role in the effective plugging of the effluent channel. 　　Relevant content:OGEM petroleum solid control equipment has always been the credibility and quality as the cornerstone of development, in the staff of the full implementation of "unity, innovation, truth-seeking, integrity" business purposes.
