铁山气田是四川气田川东地区的一个典型的多产层气田，从上到下共有４个产层。预探发现气田后，从评价工作开始到气田进入正式开发的整个过程中，充分运用经营管理手段，多学科合作开展工作：早期钻少量井就发现各产层；以“稀井广探、少井高产”为目标，从勘探开发（立体开采）的角度，整体规划、统一布署评价井；在试采中，充分利用静、动态资料计算、复核气藏储量，评价气藏；以数值模拟为主要技术手段编制整体开发方案。采用“一井两层”分采、利用产能富余井上试新层等工艺，及时建成配套的地面集输系统，加快投产时效，使气田经营效益高，是高效开发气田的成功实例。
The Tieshan gas field is a typical multi-layer gas field in the eastern Sichuan area of Sichuan gas field. There are 4 production zones from top to bottom. After the pre-exploration gas field is discovered, from the evaluation work to the formal development of the gas field, full use of management tools and multi-disciplinary cooperation to carry out the work: Early exploration of a small number of wells to find the production layer; In the trial mining, making full use of static and dynamic data to calculate and review the gas reservoir reserves and evaluate the gas reservoirs. Based on the numerical simulation As the main technical means to prepare the overall development program. The “one well and two layers” sub-mining, the use of excess production well trial of new layers and other processes, and timely completion of supporting the ground gathering and transportation system to speed up production aging, gas field operating efficiency, is a successful example of efficient gas field development.
