| 摘 要： | 舍女寺油田孔二段油藏空气渗透率26.7×10-3 μm2,开发过程中存在储层物性差、注水困难、注采井网不完善、油藏低速低效开采等问题.为此,开展了孔二段低渗油藏改善开发效果的4项研究,即提高水驱控制程度、合理驱动压力梯度、小井距加密提高连通程度和非主流线井压裂.实施后舍女寺油田孔二段油藏采油速度从0.81%上升到0.92%,最终采收率从14.8%提高到26.1%,增加可采储量38×104 t,为同类型油藏提供了改善开发效果的技术对策.

| Abstract: | In the low permeability reservoir,there exist higher pressure in water injecting,poor injecting and discovery well-pattern,low speed and low effective in the development of Member 2 of Kongdian Formation in Shenvsi Oilfield.In order to solve these problems,four suggestions are proposed to improve the development in the low permeability oil reservoir,such as improving the degree of water flooding,optimizing technique of the reasonable driving pressure gradient,infilling well spacing and increasing the interc... |
