孤东油田稠油区块自1992年投入注汽开发以来,已经过3-5个注汽吞吐周期,呈现综合含水上升,周期产油量下降,综合递减加快的生产态势,稠油井开发经济效益不容乐观。几年来的稠油开发实践表明,成本居高不下,效益较差。目前稠油井开发成本偏高,部分井开发亏本生产,部分井处于微利生产,经济效益较差。因此,降低注汽开发成本,提高开发效益是摆在油藏管理者面前的重要课题。 Since Goudou Oilfield heavy oil block was put into steam injection development in 1992, 3-5 steam injection huff and puff cycles have been put on for a long time, showing a comprehensive production increase, a decline in periodic oil production, an accelerating decline in production, an economic benefit for the development of heavy oil wells Not optimistic. Over the past few years of heavy oil development practice shows that the high cost, less effective. At present, the development cost of heavy oil wells is rather high. Some of the wells are developed at a loss and some of the wells are in low-profit production with poor economic returns. Therefore, reducing the development cost of steam injection and improving the development efficiency are the important topics facing reservoir managers.
