截至11月2日,冀东油田陆上作业区共实施二氧化碳吞吐措施41井次,有效36井次,累计增油1.4万吨,取得较好增油效果。冀东油田陆上作业区通过持续开展二氧化碳吞吐技术试验,初步掌握了二氧化碳吞吐技术控水稳油三大机理、陆地浅层油藏二氧化碳吞吐技术的选井选层条件以及二氧化碳吞吐井延长有效期生产控制技术,制定了《二氧化碳吞吐设计及施工规范》。今年年初开始,这个作业区进一步加大技术研究力度,扩大应用范围,实现了由水平井向定向井、由稠油油藏向稀油油藏、由首轮向多轮、 As of November 2, Jidong Oilfield land-based operating area implemented a total of 41 well-order measures of carbon dioxide and waste throughput, effective 36 wells, the cumulative increase of 14,000 tons of oil, achieved better oil increase effect. Through continuous carbon dioxide huff and puff (TST) experiments, the Jidong Oilfield land-based operating area initially mastered the three major mechanisms of water and oil stabilization using CO2 huff and puff technology, selected well selection and selection conditions of CO2 huff and puff overland shallow reservoirs, and prolonged and effective production of carbon dioxide huff and puff wells Control technology, developed a “carbon dioxide huff and puff design and construction specifications.” Beginning of this year, this operation area to further increase technical research efforts to expand the scope of application, achieved from the horizontal well to the directional well, from heavy oil reservoir to dilute reservoir, from the first round to many rounds,
