摘要：采油（气）工程方案是油（气）田开发方案的重要组成部份和方案实施的核心，它通过对产油（气）井和注入井采取一系列工程技术措施，达到经济、有效地提高油气井产量的目的，是实现油田开发指标和完成原油生产任务的重要工程技术保证。我国新增探明石油储量在保持高基值稳定增长的同时，储量品位总体呈下降趋势，低渗、薄层、分散区块等边际油气藏将会成为未来油气田开发的主体。必须运用新技术、新手段进行油气田开发才能保证油气产能的稳步提升。人工水力压裂是低渗透油气藏增产的重要手段，其裂缝导流能力直接影响了压后的产量。本设计根据12-86井的油藏特点，分别进行不压裂和进行压裂两种情况下不同生产阶段下产能的预测，进行举升参数的生产模拟，并设计出其生产参数和管柱结构。通过对比发现，压裂井的产能远大于未压裂井产量，设计结果为12-86井压裂投产采气工程方案，该方案对指导该井高效生产具有参考价值。

Abstract：Oil (gas) recovery scheme is the oil (gas) field development plan form an important part of the implementation of the scheme and core, it takes a series of engineering technology measures on the oil(gas) well and injection well to economy, effectively improving the purpose of oil and gas well production, is the important engineering technology guarantee to finish the oil field development task of crude oil production. With our country proven oil reserves grows in height, reserves grade overall declined, low permeability, thin bed, scattered block such as bound oil and gas reservoir will become the main body in the follow oil and gas field development. As the result, new technology and measure must be used to guarantee the production increased by oil and gas development. Artificial hydraulic fracturing is the most important step for low permeability reservoir, the fracture flow capacity directly affects the production after fracturing. According to the reservoir characteristics of 12-86 well, two production forecasts of are not fracturing and fracturing had be done, simulated the lifting parameter and designed both the producing parameter and pipe composition. By coMParing the results, fracturing well produces much more gas than the not fracturing well, so we designed a fracturing well gas recovery scheme, it would guide the well has a high effective production with reference value.
