辽河油田曙三区压裂防砂技术研究与应用
|
摘要
辽河油田曙三区油藏压实作用差,储层胶结疏松,油层出砂比较严重,自该区块投入开发20多年以来,出砂现象一直伴随着整个开发过程,对整个油藏的开发效果影响极大,随着油藏开发进入中后期,油层出砂现象趋于加剧,具体表现为出砂井增多、单井出砂量增大,因出砂导致的套变井增多、修井次数增多等。为了解决曙三区油藏的出砂问题,我们在总结原防砂技术的基础上,研究压裂防砂技术,通过现场实施表明,该项技术不仅可以有效减缓地层出砂,提高生产时率,而且可以减少因出砂导致的管理工作量,降低生产成本,延长防砂有效期,提高油井生产产能。
压裂防砂技术是依据成熟的压裂和充填防砂两种工艺方法,将“端部脱砂压裂”技术运用于其中,使其达到防砂和解堵增产的双重效果。压裂防砂技术可以使地层与井筒之间的压降降低,减少流体对地层的冲击,可以起到防止地层出砂的目的。本文从研究压裂防砂的增产和防砂机理入手,结合曙三区油藏的地质特征和出砂状况,对压裂防砂从机理到施工工艺进行系统研究,并通过现场实施不断总结经验完善,最终形成了一整套适合本区块油藏地质特点的压裂防砂系列技术,为曙三区油藏提高开发水平和开发效果提供了技术支持,取得了良好效果。
Three areas of Liaohe Oilfield Shu poor reservoir compaction, reservoir cement loose sand reservoir more serious, since the block to invest in developing more than 20 years, sand has been accompanied by the phenomenon of the entire development process, the development of the reservoir effect great impact, with the mid-and late into the reservoir development, reservoir tends to exacerbate the phenomenon of sand, concrete sand wells showed an increase in single well increase the amount of sand, because sand well casing deformation due to increase in the number of increased workover and so on. To address the three areas Shu sand reservoirs, we summarize the original in the sand on the basis of technology, research frac-pack sand control technology, through on-site implementation of that technology can not only effectively reduce the formation of sand to improve the production rate, sand and can reduce the administrative workload resulting from lower production costs, extend the validity of sand to raise oil production capacity.
Frac-pack sand fracturing technology is based on mature technology and filling sand of two methods, the "End sand fracturing" technology applied to them, to reach the sand blocking the increase of the double effect of reconciliation. Frac-pack sand control technology can make the formation and the wellbore pressure drop between the lower and reduce the impact of fluid on the formation, can serve the purpose of preventing sand production. This paper studies the yield frac-pack sand and sand control mechanism and carried out the construction process from the system, combining the Shu Three areas reservoir geological characteristics and sand conditions, and sum up experience through on-site implementation of sound, forming a complete set of features for the block of reservoir geology, and finally come to the site frac-pack sand control implementation methods for Shu Three areas reservoir development level and the development of improved path provide a technical support and achieved good results.
