对辽河曙光油田曙13938 裂缝性潜山油藏底水运动规律和剩余油分布进行研究，确定了剩余油分布方式。研究结果表明：①针对含油带剩余油，应实施补孔并配合化学堵水来进行挖潜；②针对过渡带剩余油（目前的生产井段），应实施化学堵水挖潜；③针对过渡带剩余油（早期的封堵层），应实施钻塞下返并配合化学堵水来进行挖潜。在区块开发后期，该项研究有效地解决了因底水锥进造成的油井高含水等开发问题，可为同类潜山油藏开发后期的剩余油挖潜提供新的思路，具有一定的借鉴意义。

The motion rule of bottom water in fractured reservoir of buried hill and distribution of residual oil in shu 13938 well of ShuguangOilfield are studied, and the distribution of residual oil is defined. The study result shows that it is necessary to take correspondingmeasures of tapping the potential in light of different existing forms of residual oil：① added perforation and chemical water blocking should be carried out for residual oil in oil-bearing zone； ②chemical water blocking should be carried out for residual oil in transition zone （actual oil production layer）;③drilling cement plug and chemical water blocking should be carried out for residual oil in transition zone （earlier blocking layer）．This study，which can also apply to similar bottom water heavy oil reservoir of buried hill，can effectively solve some development issues ,such as high water-cut caused by bottomwater coning in oil well of the late-period production and so on．This technology provides a newidea to potentiality exploration of residual oil in similar buried hill reservoir for the further development and has some reference value．
