Initiation Pressure

Horizontal well hydraulic fracture construction technology has already become the main development means of low permeability reservoir, and the crack initiation pressure is a key factor in fracture construction. Taking ABAQUS as the platform, combined with rock mechanics, elastic mechanics, fracture mechanics, damage mechanics and fluid-solid coupling theory, to establish horizontal well mechanical model, crack initiation law of horizontal well under different conditions were obtained by using finite element method. According to the horizontal well fracture tested data in Daqing peripheral oil fields, the crack initiation pressure and numerical simulation results are in good agreement, it shows that the numerical simulation method is reasonable, then analyze influence factor of crack initiation pressure on the basis.

Fractured-horizontal well can effectively reduce the percolation resistance near wellbore, improve the fluid mobility and enhance the production. However, in Chang 6 ultra-low permeability reservoir, BaiBao block, HuaQing oilfield, the efficiency of fractured-horizontal well is highly poor due to the production swiftly down and water cut sharply up. For studying the unsatisfying oil development by fractured-horizontal well in HuaQing oil field, the evaluation of reservoir properties and the option of stratum for fractured-horizontal well application have been performed based on the practical geological model of BaiBao block in HuaQing oil field. The numerical simulation is used to study the effect of reservoir permeability, Thickness and Aeolotropism on the production and to optimize the horizontal length, fracture spacing, half length and conductivity. The conclusion shows that Chang 63 stratum is qualified for fractured-horizontal well application. Through the practical geological model, the optimizations of horizontal length range, fracture spacing, half length and conductivity are 800m to 1200m, 77m, 150m, and 15μm2cm, respectively. The results can be conducted for fractured-horizontal well application in HuaQing oil field.

Significant Application

There is a very significant application today towards multiple zone fracturing operations in a horizontal well of low permeability reservior all over the world. But the number of the ball seat activated sliding sleeves that can be run in a well is limited because of the design and cant meet the need of volume fracturing in low permeability reservoir; Also the sleeves can only be shifted by CT, which extend the length of the operation and add to the overall costs. This paper introduces a kind of sleeve which is controlled by RFID and meet the need of volume fracturing, the number of sleeves that can be run in a well using this technology is essentially unlimited and can be operated remotely[1-3]. It is eay to operate and no intervention; It is proved by field test that this sleeve is reliable and can meet the field application.
