针对油田零散边缘井采油工作中存在的困难,提出了配备气体发动机驱动抽油的设想。通过了解天然气发动机在某油田零散边缘井矿场的试用情况,提出了推广使用气体发动机的适用范围、附件的供应、装配与维修、对生产厂家的要求、管理体制需要改革等措施。气体发动机与电动机在零散边缘井采油效益的对比表明,单机年采油成本可节约5万多元,具有良好的发展前景。 Aiming at the difficulties in oil recovery in the marginal oil well, a concept of gas pumping driven by gas engine is proposed. By understanding the trial use of natural gas engines in the fractured edge well in an oilfield, the scope of the application of gas engines, the supply, assembly and maintenance of accessories, the requirements of manufacturers and the reform of the management system are put forward. Gas engine and motor marginal oil wells in the marginal comparison of oil recovery efficiency, single-year annual oil production costs can save more than 50,000 yuan, with good prospects for development.
