摘要
由于低渗气藏低渗、低产、低丰度的地质特点,给气藏工程研究带来困难,在大牛地气田开发中,针对低渗气藏渗流机理、试井解释、产能评价、动态分析和气藏开发对策等气藏工程问题进行了研究,形成了气藏工程配套技术,对低渗致密气藏开发有重要指导意义。
By the end of 2008,according to SINOPEC data,low-permeability gas reservoirs had contributed 61 percent of pro-ducing geologic reserves and 73.8 percent of productivity respectively,which made it become primary gas reservoir.However,such disadvantages as low permeability,low yield and poor abundance became bottle neck for reservoir engineering study.Based on years of study on effluent seepage mechanism,well test interpretation,flow potential evaluation,performance analysis and development strategy in low-permeability gas reservoirs of Daniudi gas field,this paper summarizes relevant gas reservoir engineering technologies,which will plays significant roles in development of tight low-permeability gas reservoirs.
