Firstly, through a thorough analysis of the existing process flows and production data of the gas gathering stations, precise control of the inlet separation temperature of the feed gas is confirmed as an effective strategy to increase light hydrocarbon production, based on which the light hydrocarbon yield enhancement process flow and key technical parameters are optimized. Secondly, utilizing the 3D modeling software AVEVA PDMS/E3D, full-scale 3D models of the critical skid-mounted equipment are constructed, providing precise guidance for the actual transformation. Lastly, through an economic benefit analysis of both the pilot gas gathering station and all gas gathering stations, the economic feasibility of the proposed method is clarified, offering technical references and practical insights for the transformation and upgrading of similar projects within the industry.

在核测井领域,蒙特卡罗方法应用于仪器开发设计到数据解释的各个环节。通用型多粒子输运程序(Monte Carlo N-Particle Transport Code,MCNP)作为领域内开展研究和解决问题的首要选择,其使用一直以来都受到许可限制,令研究人员面临挑战。因此,FLUktuierende KAskade(FLUKA)具有开放使用权限的优势,利用FLUKA开展核测井基准模拟,对比分析FLUKA作为MCNP替代方案的可行性。利用FLUKA和MCNP分别构建具有代表性的核测井基准模型,涵盖伽马射线输运、中子输运以及伽马-中子耦合输运过程,获取了伽马能谱和密度、孔隙度等测井响应,用以评估FLUKA在低能辐射传输模拟中的表现。研究结果显示,对于低能伽马辐射输运,FLUKA获取的地层散射伽马能谱和MCNP响应之间的最大相对误差为5.37%,密度响应相对误差在3.75%以内。对于低能中子输运,二者孔隙度响应的相对误差不超过1%,并且中子诱发伽马射线能谱基本吻合。该研究通过对基准核测井问题的模拟分析,证明了可以使用FLUKA代替MCNP在核测井领域分析解决问题。
