摘要：As the oil field enters the medium and high water cut stage, the difficulty of the measures to explore the potential is increasing, the geological conditions of new production wells are getting worse, it is more and more difficult to select wells and layers, and the effect of oil increase is gradually getting worse. In order to improve the effect of oil increase, it is necessary to refine the measures to explore the potential, expand the space of well and layer selection, and optimize the fracturing process. Therefore, we drew on the successful experience of small fracture network fracturing in T oilfield, selected six straight wells for fracturing of small fracture network in the P reservoir of the S oil field, expanded the oil discharge area, raised the seepage capacity of reservoir, and improved the development effect.
