Abstract

本发明提供一种石油钻采中的用于试油层的泥浆，属于油田钻井工程领域。为了解决目前普通的泥浆材料无法满足试油层中需要防止粘土质类分散和生成沉淀物降低油气通道连通性的特殊作用，本发明提供一种用于试油层的泥浆，其特征在于，按重量份计，其配方为：膨润土25~40份；磺甲基酚醛树脂3~5份；磺化单宁0.2~0.4份；高粘羧甲基纤维素钠0.1~0.2份；石墨粉4~6份；低粘羧甲基纤维素钠0.3~0.5份；Span-800.3~0.6份；石灰石粉0.1~3份；水1000份。本发明提供的用于试油层的泥浆，其原料及含量的选择，以及pH的调节，使得配制而成的泥浆具有防止粘土质类分散和生成沉淀物降低油气通道连通性的作用，可广泛用于探井、开发井需要保护的目的层钻进、测试、试油用。

Description

用于试油层的泥浆
技术领域
本发明属于油田钻井工程领域，具体涉及一种石油钻采中的用于试油层钻进的泥浆。
背景技术
试油就是利用专用的设备和方法，对通过地震勘察、钻井录井、测井等间接手段初步确定的可能含油（气）层位进行直接的测试，并取得目的层的产能、压力、温度、油气水性质以及地质资料的工艺过程。试油的主要目的如下：
1、探明新区、新构造是否有工业性油气流；
2、查明油气田的含油面积及油水或气水边界以及油气藏的产油、气能力、驱动类型；
3、验证对储集层产油、气能力的认识和利用测井资料解释的可靠程度；
4、通过分层试油、试气取得各分层的测试资料及流体的性质，确定单井（层）的合理工作制度，为制定油田开发方案提供重要依据；
5、评价油气藏，对油、气、水层做出正确的结论。
由于试油层的特殊作用，特别需要防止粘土质类分散和生成沉淀物降低油气通道连通性，而普通的泥浆材料是无法满足此要求的。
发明内容
为解决上述问题，本发明提供一种石油钻采中的用于试油层的泥浆，采用如下技术方案：
一种用于试油层的泥浆，其特征在于，按重量份计，其配方为：膨润土25~40份；磺甲基酚醛树脂3~5份；磺化单宁0.2~0.4份；高粘羧甲基纤维素钠0.1~0.2份；石墨粉4~6份；低粘羧甲基纤维素钠0.3~0.5份；Span-800.3~0.6份；石灰石粉0.1~3份；水1000份。
进一步地，所述的泥浆的pH=9~10。
本发明的有益效果如下：
本发明提供的用于试油层的泥浆，其原料及含量的选择，以及pH的调节，使得配制而成的泥浆具有防止粘土质类分散和生成沉淀物降低油气通道连通性的作用，可广泛用于探井、开发井需要保护的目的层钻进、测试、试油用。
具体实施方式
下面结合具体实施例对本发明进行详细说明。以下实施例将有助于本领域的技术人员进一步理解本发明，但不以任何形式限制本发明。应当指出的是，对本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进。这些都属于本发明的保护范围。
