目前在油气藏的开发过程中,水平井技术比直井技术有着更好的经济效益。但这在油气藏的开发过程中,水平井的施工中存在很多的风险因素。这些风险因素容易降低施工的成功率,。所以,为了改进致密砂岩在气藏水平井分段加砂压裂的改造技术,本文简单的叙述了加砂压裂改造技术,并对气藏模型进行了一系列的分析,进而阐明了钻井与完井的实施过程及相关因素的识别和控制过程,在合理的的基础工作上,提高了水平井段加砂压裂的成功率。
At present, in the process of oil and gas reservoir development, horizontal well technology has better economic benefits than direct well technology. However, during the development of oil and gas reservoirs, there are many risk factors in the construction of horizontal wells. These risk factors can easily reduce the success rate of construction. Therefore, in order to improve the technology of subdividing sand fracturing of tight sandstone in the horizontal well of gas reservoir, this paper simply introduces the rehabilitating technology of sand and fracturing and conducts a series of analyzes on the gas reservoir model, Completion of the implementation process and related factors in the identification and control process, in a reasonable basis of work to improve the horizontal well sand fracturing success rate.
