层内生成二氧化碳驱油技术在绥中36-1油田的尝试

Attempt in SZ36-1 Oilfield by In-Stiu Carbon Dioxide Generation

层内生成二氧化碳驱油技术具有封堵高渗透层、热解堵、驱替等多重作用,在油气田开发过程中有效运用此技术可起到控水稳油作用。该技术施工工艺简单,适合于海上油气田在狭小作业空间下进行。在渤海绥中36-1油田尝试运用了此技术。经渤海绥中36-1油田H5井组的现场作业,取得较好的增油控水效果,实施后3个月增产幅度近10%。

The technology of in-stiu carbon dioxide generation plays multiple roles, including sealing high-permeability layers, hot plugging and flooding etc. By using this technology effectively, the water cut can be controlled and oil production can be stabilized during the oil and gas field development process. This technology is simple for operation, suitable for offshore oil and gas fields in the narrow working space. This technology has been used in SZ36-1 Oilfield in Bohai Sea. Through application in Well H5 of SZ36-1 Oilfield in Bohai Sea, the oil production has been increased and water cut has be controlled effectively, and oil production has been increased nearly by l 0% during three months after the application of this technology.
