低渗透油气田在我国油气开发中有着重要意义。我国发现的低渗透油气田占到新发现油气藏的一半以上,而低渗透油气田产能建设的规模则占到油气田产能建设规模总量的70%以上,低渗透油气田已经成为油气开发建设的主战场。低渗透油田单井产量低,渗流关系复杂,储层改造困难,开发效益差,试油气过程中面临一系列问题,这些问题的解决关系到试井资料的录取精确度,也是客观评价和认识油气藏的重要参照标准,必须引起重视。
Low permeability oil and gas fields in China’s oil and gas development is of great significance. Low-permeability oil and gas fields discovered in China account for more than half of the newly discovered oil and gas reservoirs, while the production scale of low-permeability oil and gas fields accounts for more than 70% of the total capacity of oil and gas fields. Low-permeability oil and gas fields have become the main battlefield for oil and gas development and construction. The low single well production in low permeability oilfield has complex percolation relations, difficulties in reservoir reconstruction, poor development benefits, and a series of problems in the process of testing for oil and gas. The solution of these problems is related to the precision of well test data acquisition and objective evaluation and understanding of oil and gas Tibet important reference standard, must pay attention.
