The Research And Application Of Fracturing Sand Control In Shu Three Areas Of Liaohe Oilfield

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.
