摘要
水力压裂是目前油气田开发过程中常用的增产措施之一,而对压裂油气井产能进行预测是评价油气井经济效益的一个重要手段。最近几年国内外一些学者对压裂气井产能预测做了相应的研究,在对影响压裂气井产能预测因素进行研究的基础上,提出了一些压裂气井产能预测的新方法。压裂气井产能预测的方法主要有:解析法和数值计算方法以及基于电模拟理论基础上的产能预测和BP人工神经网络方法等。影响压裂气井产能预测的因素较多,其中主要有裂缝的影响、裂缝面漏失的影响、应力敏感和启动压力的影响等。
Hydraulic fracturing is one of the commonly used measures of increasing production in the oil and gas field develop- ment process. Productivity prediction of fracturing oil and gas well is an important means to evaluate its economic benefits. In recent years, some scholars study on the productivity prediction and the influence factors of fracturing oil and gas. On the basis of these studies, scholars have put forward some new methods of productivity prediction. The new methods are: analytic method and numerical calculating method, and productivity prediction based on the electric analog theory and BP neural network meth- od. There are many factors to influence productivity prediction of fracturing gas wells, the main factors are the crack, crack sur- face leakage, sensitive stress and startup stress and so on.
