| 摘 要： | 坪北油田属于典型的"低渗、低孔、低压"油藏,要想实现效益开发,必须从优化设计入手,将单井投资降低到1000万元以内,实现投入产出平衡,以便取得更高的投资回报,同时慎重布井,对于井网较完善的区块尽可能按常规定定向开发,对于常规难动用储量和边部不完善的注采井网采用长平井开发。

| Abstract: | Jianghan Oilfield brings in a pressure-carrying operation device in order to solve operating problems in water injection.This device is used in regular pressure-carrying operation of oil-water wells but has some problems: firstly,different inner diameters of original downhole tool make it hard for the tool to plug in;next,different external diameter and too long tool string make the space not enough for pressure-carrying operation device to trip out;lastly,it is hard to replace the water nozzle of primary downhole of regular injection well.Therefore,the author suggests that the design for running string be improved for next pressure-carrying operation,the regular operation be carried out on the well that needs pressure-carrying operation to prevent the strings from breaking or corroding and existing devices be improved to meet overhaul operation. |
