拖市油田难动用储量开发对策研究

Countermeasures for Hard-to-Recover Reserves in Tuoshi Oilfield

拖市油田难采储量规模大,达353.79×104 t,是新沟嘴组最难动用的油田,有效地盘活这部分难动用储量是决定拖市油田长期稳定发展的关键。在现有的经济技术条件下开发拖市油田难采储量,必须遵循"整体评价、先肥后瘦、依靠科技、注重效益"的总体方针,择优开发相对高效区块,实现经济效益最大。针对拖市油田的油藏地质特点,应分别采取深化油藏描述、加强储量评价,优化开发方案设计、开展水平井试验等对策。

Tuoshi Oilfield has a large number of hard-to-recover reserves. Efficiently using it is crucial for making Tuoshi Oilfield develop sustainably. Under the condition of existing economy and technology, it is necessary to follow the total guidance of general evaluation, relying on science and technology and targeting benefit, exploit relatively efficient blocks first. According to reservoir geological features in Tuoshi Oilfield, it is necessary to take countermeasures including deepening reservoir description respectively to strengthen reserves evaluation, optimizing development plan design and launching horizontal well test with a view to improving producing extent of hard-to-recover reserves in Tuoshi Oilfield.
