Analysis on Fracturing Effect of Film-Coated Sand in a Reservoir

Abstract

Reservoir Development is poor in a certain oil field of a factory. With the extension of development period, the water cut of oil layer increases year by year, the adjustment of water injection is difficult, the production decreases rapidly, the number of high water cut wells increases, and the developed oil layer is basically watered out, in view of the fact that it is more and more difficult to select wells and layers by conventional fracturing and oil-increasing measures, combined with the mechanism of plastic-coated sand water-controlling fracturing technology, this paper focuses on the analysis and discussion of the sand fracturing effects of the high water cut wells caused by pollution in the same layer, the high water cut wells with high water cut and the high water cut wells with high water cut and the high water cut wells with plane contradiction and the low productivity of the non-main oil layers after water flooding in the main layer, the effect of the measure reaches or exceeds the effect of conventional fracturing, verifies the practicability and effectiveness of the technical conditions for well selection, further excavates the potential of an oil layer in the oilfield, broadens the range of well selection and increases the potential of the measure.
