煤层气钻井过程中的储层保护技术研究

Research on Reservoir Protection Technology in the Process of Coalbed Methane Drilling

煤层气通常又被叫做煤层甲烷,是目前比较常见的天然气资源。我国社会经济在不断发展,我国需要更多的天然气,因此要求煤层气开采技术有着更高的开采效率,确保其不会对储层产生破坏。介绍了储层特征,并论述了当前开展储层气钻井过程中的储存保护难点,分析比较了几大主流煤层气储层安全保护技术,希望对煤层气的开采工作有所帮助。

Coalbed methane is usually called coalbed methane,which is a relatively common natural gas resource at present.my country’s social economy is constantly developing,and my country needs more natural gas.Therefore,this requires coalbed methane mining technology to have a higher mining efficiency to ensure that it will not damage the reservoir.Therefore,the reservoir characteristics are introduced,and the difficulties of storage protection in the current process of reservoir gas drilling are discussed,and several mainstream CBM reservoir safety protection technologies are analyzed and compared,hoping to be helpful to the mining of CBM.
