Research On Shale Gas Fracturing Technology Of Jiaoshi Area

Shale gas reservoirs must be efficiently produced by fracturing.Shale gas fracturing has obvious differences with conventional fracturing in fracturing process,sand size and so on.Due to the different reservoir characteristics of different blocks,so different shale gas reservoirs used technology and liquid systems are not the same.In order to effectively form a complex fracture volume increase shale gas production,it is important to optimize fracturing technology,liquid,proppant,construction scale according to the actual situation of the construction process staged.This paper,through literature research combined with field test,has studied in detail reservoir characteristics of shale gas,shale gas fracturing stimulation mechanism,simultaneous and zipper fracturing technology and staged fracturing process,etc.At the same time,this paper optimized staged fracturing parameters and selected out perforating parameters for JiaoShi area.This paper,according laboratory research and field practice,researched the different the characteristics of acid,slippery water,glue and selected out the fracturing fluid system for the target area.The paper researched the proppant migration in the non-crosslinked fluid migration,multi fissure's impacts on proppant distribution and summed up a series of fracturing sand and precautions.According to the geological characteristics of JiaoShi area,the paper optimized proppant combination for this area.This article studied shale gas fracturing fracturing analysis,acid treatment process,glue dispose after sand ratio sensitive,temporary plugging volume fracturing technology in casing deformation wells,etc.Combined above findings with JY-42 shale gas platform's simultaneous fracturing,effectively guided the fracturing of the platform and achieved good results.
