Perforation density and orientation angles are the most important factors of all to affect formation fracturing pressure.

主要结论包括射孔密度和射孔方位角是影响地层破裂压力的主要因素。

Deepwater, with the properties of low temperature, high pressure, low formation fracturing pressure, impacts the cementing work significantly.

海洋深水温度低、压力大、地层破裂压力小，对固井作业产生了较为严重的影响。

Due to the higher thermal expansion of fluid in low permeability shale, the super pore pressure may lead to the development of effective tensile stress and even formation fracturing.

由于低渗透页岩地层流体高温膨胀导致的超孔隙压力，有可能产生有效拉张应力，严重时会导致地层破裂。

But these days, he's house hunting in San Antonio, the biggest city near the booming Eagle Ford Shale formation, a prime location for hydraulic fracturing.

He says that the Monterey geological formation is uncommon, and at present, hydraulic fracturing cannot work there.
