摘要:
水力压裂是水平井常见的增产措施,准确预测压裂后水平井的产能是水平井压裂设计的重点和难点工作之一。根据势的叠加和干扰理论,借用等效井径的概念,建立了压裂水平井产能计算的新公式。基于此公式,研究了存在多条裂缝时,各个裂缝长度对水平井产能的影响。研究结果表明:各个裂缝长度差异较大时,油井的增产效果较差; 压裂水平井的增产效果,与外侧裂缝长度关系更大。
Abstract:
Hydraulic fracturing is a common stimulation of horizontal wells,and predicting the production of horizontal wells after fracturing is one of the important and difficult work.To get a more accurate calculation method of the fracturing horizontal well production capacity,the theory of potential superposition and interference were applied, the concept of horizontal well of equivalent diameter was utilized, the new formulae for calculation of fracture in horizontal well productivity was established. Base on this formula, this paper studied the length of cracks effects on horizontal well productivity when multiple fissures exist. The results show that when the crack length difference is bigger, the well stimulation is poorer. The stimulation result is determined by lateral crack length.
