Research And Application Of Sand Prevention Technology Hydraulic Fracturing

In recent years, the exploitation of the development of the technology and thecomprehensive use of various process technology, makes the fracturing technology has beenwidely used in all kinds of reservoir. For low permeability reservoir is building the new seam,for higher permeable reservoirs is lifted the pollution and congestion of near wellbore area.As s result， The problem of sand after the oil well fracturing is very outstanding, whichserious restricts the oil well productivity of normal exertion.IN this article, by means of analysis to the formation sedimentary rhythm andstratigraphic physical property and the of the formation of sand force, to determine the causeof the formation sand production. Constant mechanical sand then lengthened the sand, such asa pump laser slotted tube of sand, gravel pack to the test and comparison of the sand with thefracturing process of chemical sand approach.owing to the short validity and failure fastfeature of mechanical sand control，and must be clear angr change in time, relatively belongto passive sand control. In order to realize the real sense of sand control, we must start fromthe formation, fully understand the relevant data of the strata, we have to use not onl y theeffective mechanical sand control technology, but also the reasonable chemical sand controlprocess.This paper makes a study of the mechanical sand control to gravel filling processtechnology is given priority to, chemical sand control with resin sand sand control fracturingtechnique is given priority to, which have become the main technical means to solve theproblem of sand after the oil well fracturing. To improve well productivity and to achievecapacity to maximize the scientific optimization and pressure fracturing constructionparameters of flowback control proppant back.Construction parameters of the optimizationafter the pressure on the fracturing effect sand has an important impact on many of thecurrently used in fracturing parameters optimized software, such as Gohfer, Fracpro MfracStimplan fracturing design and simulation software, effectively guide the interior designandsite construction, fracturing design from concept stage to really go to science.ResinShafang sand fracturing technology to adapt to the status of the Fuyu Fuyu after fracturing theactual situation of the sand, in essence solved, not only in Fuyu that the whole of Jilin Oilfieldhas a wide range of value.
