摘要
介绍目前常用的压裂缝高控制技术及其适用范围,提出一套适用于各种控缝高压裂工艺的通用设计计算方法。针对M气田S气层的实际情况选了施工排量、压裂液粘度、隔层应力差、杨氏模量和滤失系数等参数,通过计算得出这些参数对缝高的影响值。
All types of up-to-date controlling fracture height technology applied domestically and abroad are comprehensively described, and also the conditions suitable for their applications are indicated. A generally applicable calculation method of design of various types of controlling fracture height technology is set forth. In the light of this method, selected five influence factors on fracture height, including operational displacement, poor stress in restraining barriers, viscosity of fracturing fluid, young＇ s modulus and leakoff coefficient and obtained the effects of foi＇mation and operation parameters on the facture height. This research guided fracture design of its height control in M gasfield.
