胡尖山油田低渗透油藏安201区块和胡154区块在开发中存在油井方向性见注入水问题,其中安201区油井总数199口,39口油井已被注入水水淹,25口油井已地关。产量、储量损失巨大,开发矛盾突出。本次在胡尖山油田实施注水井深部调驱18口,其中安201区16口,胡154区2口。针对安201裂缝发育程度高的,水线突破能力强的特点优选出粘土凝胶和HSG-1油井堵剂,针对胡154区裂缝发育程度低优选有机为主堵剂,提出“裂缝型暴性见水”和“孔隙型温和见水”两种见水油井治理思路,通过实验均取得较好效果。
There are wells in the Block 201 and Hu 154 blocks in the Hujianshan Low Permeable Reservoir. There are 199 wells in the Zone 201, of which 199 wells are in total. 39 wells have been flooded and 25 wells have been flooded Already closed. Production, reserves huge loss, prominent development contradictions. The implementation of injection wells in the Hujiashan Oilfield deep drive 18, of which 201 District 201, Hu 154 District 2. In view of the high degree of fractures developed by An 201 and the strong water breakthrough ability, clay gel and HSG-1 oil well plugging agent are preferred. In view of the low degree of fracture development in Hu 154 area, See the water “and ” pore see mild water "see two water wells governance ideas, through experiments have achieved good results.
