Parameters Optimization Of Dense Oil Physical Fracturing Research In Changji Oilfield Of Lu Caogou Group

Fracturing is a volume in recent years emerging mining measures to enhance reservoir recovery.Volume fracturing technology in the process, to enhance reservoir recovery because of its natural fracture can communicate greatly strata, therefore in the process of fracturing has a unique advantage.But at the same time we in application volume fracturing is faced with some problems, such as fracturing as well as the crack length, width, Angle, these are the volume of the effectiveness and feasibility of fracturing effect.In order to improve the density of reservoir volume fracture fracturing effect, this paper established a finite element mathematical model considering start-up pressure gradient, set up two kinds of complex fracture description method, the arbitrary triangular element and line element describes the formation and fracture.In this paper, under the condition of natural energy exploitation, single well as the research object, in view of the volume of fracturing fracture parameters on the effect of horizontal well development effect were studied.This paper mainly from the crack fracture network form, fracturing series, and a half long, horizontal section length for simulation calculation.Through analysis and comparison of the pressure distribution and saturation distribution, and the fitting curve of moisture and producing fluid volume output fitting curve and the fitting curve, the oil well fracturing effects is analyzed under different fracture parameters, the fracturing series is given, the optimal fracture half-length values, for the field application of dense reservoir volume fracturing technology provides certain theoretical guidance.
