terrestrial stress

基本解釋

And the terrestrial stress direction also can be calculated by dipole wave data.
利用偶極橫波測井計算地應力方向的公式法。
Terrestrial stress is a main control on hydrostatic head of reservoir, and its gradient powers oil, gas and water migration.
地應力是影響儲層沉積水水頭的主要因素，地應力梯度是油氣水運移的主要驅動力。
This paper introduces the principles and analysis method of how to determine the terrestrial stress using the archeomagnetism measurement combined with differential deformation analysis.
介紹了古地磁測試結合差應變分析確定地應力參數(shù)的基本原理以及分析方法。

地應力
The result shows that in the combined pattern of hydraulically fractured horizontal well and vertical well,the azimuth of the horizontal well is optimum in parallel to the smallest terrestrial stress;inverted nine-spot pattern shall be adopted;the limit drainage radius for F147 reservoir is 110m with consideration of threshold pressure gradient;the optimum well pattern and spacing is 400 m × 200 m(well spacing × array spacing).
結果表明:該塊壓裂水平井與直井聯(lián)合布井井網(wǎng)方位應以水平井位置平行于最小地應力方向為最優(yōu);井網(wǎng)類型應選擇反九點井網(wǎng);考慮啟動壓力梯度下F147區(qū)塊極限供油半徑為110 m;井網(wǎng)井距應該選擇400 m×200 m(井距×排距)為最優(yōu)。
