水力压裂微地震裂缝监测技术及其应用
|
摘要
水力压裂形成的裂缝渗透率和导流能力是影响压后效果的重要因素。利用裂缝监测技术可以分析裂缝扩展规律,优化指导压裂设计。由于该技术可监测裂缝生成、评价压裂效果,为调整压裂设计和油气田开发方案提供参考依据,对低渗透油藏增产具有十分重要的意义。文中首先阐述了水力压裂微地震裂缝监测技术的原理和特点,其次结合某油田水力压裂微地震资料,通过反演微地震震源位置信息,推断出每次压裂产生的裂缝参数,并进行了水力压裂裂缝发育和演化的过程预测。研究结果表明,水力压裂微地震裂缝监测技术可以用于指示裂缝位置、分析裂缝发育情况,并辅助微地震位置精确反演,指导水力压裂施工作业。
The permeability and flow conductivity of fractures caused by hydraulic fracturing are key factors to affect the results after fracturing.Microseismic fracture monitoring technology(MFMT) can be used to analyze fracture expansion laws and guide the optimization of fracturing design.Since MFMT has many advantages such as monitoring fracture formation and evaluating fracturing result,which can provide reference basis for adjusting fracturing design and compiling scheme and has inmportant significance in improving production of low permeability oil reservoirs.Firstly,this paper the explained principle and characteristics of MFMT.Then,combing with the MFMT dataset of one oilfield,the microseismic source position was inverted and the fracture parameters in each fracturing process were derived.Finally,the processes of fracture development and evolution were predicted and evaluated.Results show that MFMT can be used in indicating the positions of fractures,analyzing fracture development,assisting with accurate inversion of microseismic positions and guiding the process of hydraulic fracturing.
