摘要:

为提高榆树林油田缝网压裂方案设计水平，建立了与工程因素相关联的储层改造体积计算模型，分析了地质因素及工程因素对储层改造体积的

影响。地质因素决定了大规模体积压裂是否形成缝网，其中水平主应力差对缝网体积影响较大，随着水平主应力差增加，储层改造体积逐渐减小；岩石的脆性越大，储

层改造体积越大。工程因素可改变缝网的波及范围，其中施工排量对缝网宽度影响较大，排量越高，缝内净压力越高，形成的缝网宽度越大。榆树林油田最佳施工排量

是7～8 m3/min，具体到单井，应根据井网及砂体展布，对总施工液量进行优化。该方法计算得到的缝长、缝宽与井下微地震监测结果误差在10%以内，可有效指导缝

网压裂方案设计，为压裂效果分析提供参考。

Abstract:
 

In order to improve the network fracturing scheme designing level of Yushulin Oilfield, a reservoir stimulation

volume calculation model associated with engineering factors was established, and the influence of geological factors and engineering factors on

reservoir stimulation volume was analyzed. It is found that geological factors determine whether largescale volume fracturing can form

fracturenetwork, and the horizontal principal stress difference has a great influence on the volume of the fracture network. With the increase of

horizontal principal stress difference, the volume of reservoir stimulation decreased gradually. The larger the brittleness of rock, the larger

the volume of reservoir stimulation is. Engineering factors can change the influence range of fracture network, in which the construction

displacement has a greater impact on the width of fracture network. The higher the construction displacement, the higher the net pressure in the

fracture, the larger the width of fracture net. It can be concluded that the optimum construction displacement of Yushulin Oilfield was 78 m

3/min. The total construction fluid volume should be optimized according to the well pattern and sand body distribution when a specific single

well was planned. This method can effectively guide the network fracturing scheme design and provide reference for the analysis of fracturing

effect.
