黄原胶在大港枣园油田的应用

Application of xanthan gum in the Zaoyuan oil field.

枣园油田地质条件复杂 ,近几年利用多种调剖剂对该区注水井进行调剖 ,效果不够理想。为缓解该区层内与层间矛盾 ,达到控水增油目的 ,利用RS决策系统软件 ,应用黄原胶调剖剂 ,进行科学优化 ,设计与实际情况吻合较好 ,调剖以后 ,区块水驱效果得到较大的改善。在我国东部油田地质条件复杂、出砂严重的地区 ,应用新技术方法及合适的调剖剂进行整体区块调剂 ,可实现“增油控水” 。

Geologic features of Zao yuan oil field are complicated, Recently, many kind of profile control liquid we re used to inject under ground through water well, but the result wasn't always ideal. In order to decrease conflict between strata profile and to realize the aim of “increasing oil production and controlling water production”, a program of “RS DECISION SYSTEM” was applied to make an optimum application of the xan than gum, the design of the program was proved to be identical with exercise res ult. After putting into production, the water production can be controlled obvio usly. Briefly, so complicated geologic situation and terrible sand production in eastern China, some of newly technologies and profile control liquid should be applied to “increasing oil production and controlling water production” by xan than gum in entire water injection well, and to increase the economic and social effects for all oil field.
