Geological features and reservoir exploration of Shawan formation

Liu Chuanhu,Wang Xuezhong

Strategic Study of CAE 2011, Volume 13, Issue 4, Pages 87-95

Abstract:

Shawan exploration of Juggar Basin was faced with exploration problems of small scale oil sand, thin reservoir and rapid changes in lithology. In 2005, Pai 2 Well in Shawan formation drilled oil layer. It obtains 49.6 t/d industrial oil and the ground oil viscosity is 1.6 mPa·s. Practice and boldly exploiting contributes to Shawan's breakthrough of shallow, light oil and high lithologic oil reservoir, and high precision three dimensional seismic technology has played a crucial role. Chepaizi region of Shawan formation has double gathered and the "three floors" oil and gas accumulation mode of multiple oil source transporting, multi line oil, multi type enrichment and multi-grade coexistence characteristics. Shawan's light oil sand body shape has a good corresponding relationship with amplitude property, and the oil water boundary can be identified by seismic attributes. Oil of thin oil is oil lower limit, and powder and fine sandstone is lithologic lower limit, permeability of 0.022 μm² and porosity of 20 % is lower limit for the properties. Reservoir interval transit time is greater than 300 μs/m, resistivity is greater than 1.5 Ω·m and resistivity index is greater than 5.5. 23 reservoirs have been found in Shawan.
