【摘要】：长宁-威远区块作为国家页岩气开发示范区,其勘探开发工作快速推进,预计到2020年天然气产量将达到100×10~8m~3/d。为了适应示范区高效、低成本的建设需要,各项钻完井技术不断优化完善。示范区页岩气地面测试技术作为钻完井技术组成之一,除了具备常规井地面测试作业功能外,还需满足试采、井口高压除砂、压裂砂堵应急处理和钻磨桥塞地面压力控制流程等多项作业。地面测试流程优化十分必要,但影响地面测试流程优化的因素也较多。文章作者从长宁-威远区页岩气气藏特征、地理环境、工厂化拉链式作业模式、作业功能需求等方面分析对地面测试试流程优化的影响,并提出了下一步地面测试流程优化的建议。
[Abstract]:Changning-Weiyuan block, as a national shale gas development demonstration area, its exploration and development work is advancing rapidly, and its natural gas production is expected to reach 100 脳 10 脳 8 m / 3 by 2020. In order to meet the needs of high efficiency and low cost construction in the demonstration area, all kinds of drilling and completion techniques are constantly optimized and improved. As one of the components of drilling and completion technology, shale gas surface testing technology in demonstration area not only has the function of conventional well surface testing, but also needs to meet the requirements of test production and high pressure sand removal at the wellhead. There are many operations, such as emergency treatment of fracturing sand plug and ground pressure control flow of drilling and grinding bridge plug. It is necessary to optimize the ground test process, but there are many factors that affect the optimization of the ground test process. This paper analyzes the influence of shale gas reservoir characteristics, geographical environment, factory zipper operation mode and operation function requirements on the optimization of surface test and test process in Changning-Weiyuan area. Some suggestions on the optimization of ground test flow in the next step are put forward.
