Research On Natural Gas Recovery Technology In Remote Wells

Due to the limitation of temperament and geographical environment by itself, the remote Wells gas can't be used in situ. Remote Wells in order to reduce the excessive gas vent processing, to reduce environmental pollution, to save non-renewable resources and to meet the demand of remote well development, so the study of remote Wells gas recovery technology. Based on remote natural gas Wells as the research object, this paper summarizes the applicability of various recovery processes a variety of conditions. And the scene of the actual remote Wells gas recycling technology scheme design, provide theoretical basis for the remote Wells gas environmentally safe recycling. The main research content is as follows:First of all, according to the remote Wells is temperament types and areas, analysis the recycling cannot be the cause of the network recovery. And then Study the temperament of various remote gas well and geographic conditions. Make a systematic comparative study on gas recovery technology. Conclude that remote Wells gas recovery technology applicable range.Main consideration has a temperament of the requirements, the geographical position, use requirement, transportation cost, adaptability and security, etc. It used the SWOT model to research technology research. It sums up the remote Wells gas recovery processes applicable range.Using the law of the summary of remote Wells A and B the block recycle technology design. Design is suitable for A and B the block remote Wells gas recycling technology solutions. The following detailed design for each unit. The key of the well remote gas recycling process units are HYSYS software simulation. Recycling technology design completed the economic evaluation and feasibility analysis. The remote Wells gas recovery technology requires special equipment device prizing integrated research. So I can adapt to change operation and quick disassembling and other special requirements.Through the above analysis the following conclusions:This article summarizes the remote Wells gas recycling technology selection rule, so that we can remote Wells of different blocks in recycling technology scheme design. A block using liquefied recovery technology. Block B to take compression recovery technology. Remote Wells recycling design is to use device prizing device. Easy installation and maintenance, static simulation is feasible and reliable in practical application. It completes the economic evaluation, found 5×104m3/d remote Wells gas recycling device the strongest ability to resist risks. Risk factor for LNG cost price is the most sensitive. Risk factor for CNG use frequency is the most sensitive.
