The tight oil reservoir is abundance in shengli oilfield and has a good exploration prospects, and overall "deep", "small", "thin" , "poor" , "scattered" geological features, It main performance in the development was conventionally low or no productivity, the initial production decline, late decreasing slowed and original watercut is 35%, to deepen the study of the percolation mechanism, the use of numerical reservoir simulation technology, the long horizontal segment of the multi-stage fractured horizontal well geological parameters (fracture spacing, fracture half-length, horizontal length, fracture conductivity, etc.)optimized design, the successful implementation of the long horizontal segment multi-stage fractured horizontal wells( Fan 154 - P1), initial production is five times higher than the same period in straight well, to achieve the highly efficient development of such oilfields.
