中文摘要：

东濮凹陷发育一系列深层致密凝析气藏,由于其复杂性和特殊性,开发效果和效益差,开发难度大。但研究发现,该类气藏在整体难动用背景下存在局部可获得开发效益的相对优质储量。针对这一特点,提出此类气藏在目前技术经济条件下,实现经济开发的有效途径就是通过可动用性分析,确定气藏内的相对优质储量,优先对这部分储量进行开发。并以该类气藏中的典型区块——B55块为例,在经济界限研究的基础上,引入储能系数,通过相关性分析建立了可动用储量的评价和分类标准,并依此标准开展了储量可动用性评价。在评价结果基础上,针对不同类型储量,提出了相应的开发技术对策,为此类气藏的经济开发指明了方向。

英文摘要：

There are a series of low-permeability deep condensate gas-reservoirs in Dongpu depression. Although this category of gas-reservoirs are hard to be developed because of their low productivity and economic benefit, there are still some relative high-quality gas reserves in somewhere of the reservoirs which can be produced efficiently. In view of this characteristic, this paper puts forward that the effective way to exploit this kind of reservoirs is to determine the quantity and distribution of the relative high-quality reserves in these gas-reservoirs and to develop these reserves first. Based on B55 Block as a typical example, the standard on how to classify the available reserve of this category of gas reservoirs is established with the parameter of energy storage coefficient and the method of correlation analysis on the basis of economic boundaries study. According to this standard,this paper assesses the available reserves in B55 block and put forward the corresponding development technology strategies which make the economic development route for such gas reservoir.
