Abstract: In order to explore and solve the imaging problem of artificial fracture network during horizontal well volume fracturing and bench top zipper fracturing of shale reservoir in Jimsar block, Junggar Basin,high density dense cutting volume fracturing was adopted to carry out reservoir stimulation,large displacement construction can meet the requirements of full opening of multiple clusters and fractures,reverse mixed fracturing process of slick water and guar gum can realize high-efficiency fracture making and sand carrying, and combined with a variety of particle size proppant,it can effectively fill micro fractures and artificial fractures. The artificial fracture network of shale oil horizontal well was identified by microseismic monitoring technology. The results show that faults and natural fracture zones have influence on microseismic events attribute characteristics,and events attribute characteristics can also show the development degree of faults and natural fractures. Under large-scale volume fracturing,the artificial fractures of four wells in the study area were connected with each other horizontally, forming a complex fracture network. The daily oil production in the initial stage of production after fracturing has been greatly improved,and it can provide a technical basis for long-term and efficient development of shale oil in this area.

Key words: shale oil, dense cutting volume fracturing, reservoir stimulation, microseismic monitoring, network evaluation, Jimsar sag
