Abstract: This article discusses Low-Cretaceous reservoir stabilizing production problems and main ideas as follows:to use high-tensile proppant improving proppant crushed problem, that the test-result of Changqing oilfield proved that it has improved well production higher than quarts sands.Especially,formost wells producing 2-3 years later,the effect is obvious.Before CPF(Ceramic Proppant Fracturing),we must study Yanchang group carefully and learn the reservoir character ization,such as permeability and poroisity,subsequently select some wells to fracture it.The results of pretest are well-demonst rable and suggest this technology can be expanded in all oilfields.
