【摘要】：三站气田增产技术应用与研究主要是针对,该气田弱水驱气藏的生产现状,其边水不活跃,开采时主要依靠气驱。为了更好的开发好气田,达到因地制宜的目的,采取具有针对性的开发政策,由于气井自身条件及生产情况的不同,如何优选确定泡沫排水制度、应用优选管柱技术是气田前期排水采气的主要手段。在三站气田开发中后期,排水效果会变差或者无效,选择应用新的排水采气工艺势在必行,开展对柱塞排水采气技术及涡流排水采气技术的研究,以作为气田排水采气的技术储备。在三站气田开发中后期,随着新井投产数量的减少,如何提高和挖掘老井产能,成为提高产量的重要手段,本课题通过对一口老井实施补孔措施,分析措施效果,为该气田后续老井措施提供参考和依据。针对三站气田一口水平井,投产后未达到设计产能。试井表皮系数资料显示储层污染,为提高采收率进行酸化解堵试验。预计采取逐级打滑套分段酸化工艺管柱进行试验。试验后能使储层污染减轻,产气量提高,达到了提高采收率目的,同时对水平气井分段酸化管柱的应用进行评价。本课题主要针对三站气田实际情况,有针对性的选取对三站气田的部分气井进行合理分类,在分类基础上对该区气井进行产能落实;对气井产水特征进行分析,制定合理泡排制度。选取三站气田10口新投产气井,进行了管柱优选,确定了合理的生产制度。另通过对气井生产情况的统计研究,选取有代表性的2口试验井进行柱塞举升试验。根据涡流排水工艺选井原则优选1口试验井。对一口老井实施补孔措施,并对其效果进行跟踪分析。实施水平井酸化措施,解决近井地带污染,并对其效果进行跟踪分析。本人一直从事和参与气井排水采气及措施研究与应用,从中积累了丰富经验,为完成三站气田高效开发分析与研究奠定良好的技术基础。
[Abstract]:The application and research of Sanshen gas field are mainly aimed at the production status of weak water drive gas reservoir in this gas field, its edge water is not active, and its production mainly depends on gas drive. In order to develop the gas field well and achieve the aim of taking measures according to the local conditions, a targeted development policy is adopted. Due to the difference of the gas wells' own conditions and production conditions, how to select and determine the foam drainage system, The application of optimal string technology is the main means of drainage and gas recovery in the early stage of gas field. In the middle and late stage of the gas field development at three stations, the drainage effect will become worse or invalid. It is imperative to select and apply new drainage gas production technology. The research on plunger drainage gas production technology and eddy current drainage gas production technology is carried out. It is used as the technical reserve of drainage gas production in gas field. In the middle and late stage of development of Sanshang gas field, with the decrease of the number of new wells put into production, how to improve and excavate the productivity of old wells and become an important means of increasing production rate. It provides a reference and basis for the follow-up measures of the old well in the gas field. For a horizontal well in Sanzhou-gas field, the design productivity is not reached after putting into production. Well skin coefficient data show reservoir pollution, acid plugging test is carried out to improve oil recovery. It is expected to adopt step by step skidding sleeve stage acidizing process string to carry on the test. After the test, the reservoir pollution can be reduced and the gas production rate will be increased. The purpose of improving oil recovery is achieved. At the same time, the application of acidified tubing string in horizontal gas wells is evaluated. This subject mainly aims at the actual situation of the three stations gas fields, selects the reasonable classification of some gas wells in the three stations gas fields, and implements the productivity of the gas wells in this area on the basis of the classification. The characteristics of water production in gas wells are analyzed and a reasonable bubble discharge system is established. In this paper, 10 new gas wells are selected from three stations gas field, and the optimum selection of tubing string is carried out, and the reasonable production system is determined. In addition, through the statistical study of gas well production, two representative test wells are selected to carry out plunger lift test. According to the principle of eddy current drainage, one test well is selected. The hole filling measures are carried out in an old well, and its effect is followed up and analyzed. The horizontal well acidizing measures are carried out to solve the pollution in the near well zone, and its effect is followed up and analyzed. I have been engaged in and participated in the research and application of gas well drainage gas recovery and measures, and accumulated rich experience from it, which lays a good technical foundation for the completion of the analysis and research on the high efficiency development of three stations gas fields.
