【摘要】 旅大4油田多年开发生产中逐渐暴露出一些问题。根据海上油田调整高风险高投入及本油田自身规模不大的特点,在生产中贯彻滚动调整思路。油田先后经历三化调整:探边、应用地震属性评价潜力砂体;提高井网控制程度;完善注采井网、应用水平井同井抽注技术。通过滚动调整,油田产量稳中有升,开发效果得到明显改善。更多还原

【Abstract】 LD4 oilfield has some problems by several years’ development.LD4 oilfield adjusted three times by carrying out the thought of progressive adjustment by combining the characteristic of high-risk and high-payout in offshore oilfields and its small-size reserves last years.They are bonder exploring,evaluating potential reservoir using seismic attribution,improving well pattern controlled level,consummating injection-production pattern and actualizing the technology of both pumping& flooding in one horizontal well.The productions of the oilfield is sustained and going up.The development effects are improved obviously.更多还原
