川西须家河组2段气藏属于低渗低孔致密深层气藏，地层压力和破裂压力高。

Formation drillability is related to formation compact degree and pore fracture degree, so NDR can reflect formation pore pressure state.

地层可钻性与地层的压实程度和孔隙破裂程度有关，因此NDR可以反映地层孔隙压力的情况。

To strong stress sensitivity formation, low BHP reduces pore fluid pressure of near wellbore are which results in the closure of formation fracture.

对于应力敏感性强的储集层，过低的井底压力降低了近井地带地层的孔隙流体压力，导致裂缝趋于闭合。同时，井壁失稳的可能性也大。

According to development data and the logging data, this paper studied the distribution of crustal stress and set up the collapse pressure model and formation fracture pressure prediction model.

根据测井资料和开发资料研究群库恰克地区区块地应力分布大小，建立了研究区块地层坍塌压力、地层破裂压力预测模型。
