根据地层测试提供的表皮系数等参数,分析了胜利油田不同类型油藏从钻井到试油阶段的污染状况、主要污染原因及对策。指出不同类型的油气藏、因遭受污染损害的机理不同,其污染比 例和程度也存在较大的差异。其中裂缝、孔洞发育的潜山油藏及火成岩油藏污染比例大、程度重,其 次是高、中渗透砂岩油藏,而低渗透油藏污染比例小,程度轻。
根據地層測試提供的錶皮繫數等參數,分析瞭勝利油田不同類型油藏從鑽井到試油階段的汙染狀況、主要汙染原因及對策。指齣不同類型的油氣藏、因遭受汙染損害的機理不同,其汙染比 例和程度也存在較大的差異。其中裂縫、孔洞髮育的潛山油藏及火成巖油藏汙染比例大、程度重,其 次是高、中滲透砂巖油藏,而低滲透油藏汙染比例小,程度輕。

According to the skin effect of well test analysis, the welldamaged state can be divided into three type: the first, the buried hill reservoirs and the igneous reservoirs are sickly damaged; the second, the middle permeability sand reservoirs are damaged in some grade; the last, the low permeability reservoirs are slightly damaged. Since the reservoir types are dif ferent, the damaged mechanics and reasons are different also. The damaged grade is different in differ reservoirs. By using the well test data, the damage rules and countermeasure of different type reservoirs are given in this paper.
