| 摘 要： | 本文根据压裂施工停泵后裂缝仍有延伸的问题,提出了一种利用压裂后压降曲线早期段求解裂缝参数的方法。利用该方法可求得压裂液滤失系数、停泵后裂缝延伸时间及延伸长度、停泵时裂缝的长度与宽度、闭合后的缝长及缝宽、闭合压力与闭合时间和最小水平主应力。文中给出了计算实例。

| Abstract: | With consideration of the extension of fracture after shut-in, this paper proposes a method for defermination of fracture parameters using shut-in decline curve.By this method,some parameters, such as fracture fluid lo sscoeff icient, fracture extending length and extending time after shut-in, frac -ture length and width at shut-in, propped length and width, closure pressure and closure time, and the minimum horizontal stress, can be obtained. An calculation example is given and the calculation results are analyzed. |
