现河梁11断块油藏堵调剂的研究与应用

为了做好史南油田梁11断块油藏的控水稳油工作，依据油藏条件的特殊性，采取了适宜的堵水调剖技术。该技术以油藏为基础，根据高温高矿化度的特点研制出复配聚合物／有机铬冻胶堵调剂及其施工工艺，进行了室内试验和初步的现场应用。结果表明：所研究的复配聚合物／有机铬冻胶堵调技术适用于梁11断块油藏条件，可作为改善注水开发效果的有效措施之一。

Study and Application of a Water Shut off and Profile Modification Agent for Reservoirs of High Temperature and High Salinity in Liang 11 Fault-Block

In order to control water cut to stabilize oil production in Liang 11 fault block of Shinan oil field,the suitable technology of water shutoff and profile modification was used according to the special characters of reservoir.Basing on high temperature and high salinity,composed polymer/organic chromium gel plugging agent and implementation technology was developed due to the characters of reservoir.Laboratory experiments and preliminary applications are processed.The result shows that the newly development composed polymer/organic chromium gel plugging agent and implementation technology is suitable to the situation of the reservoir of Liang 11 fault block,and it can be used as one of the effective methods of improving the effect of water flooding.
