测压取样资料在油气勘探中的应用越来越受到重视,在解决复杂油气井的测井解释、连通性等方面发挥了重大作用。特别是储层烃类气与二氧化碳的识别成为现在勘探阶段非常有效的手段。井下流体分析及取样是确定流体性质的关键,选择合适的探针与光学流体分析模块组合,不但提高了泵抽取样的成功率,节省了作业时间,还降低了作业成本与测井作业风险获得的流体性质参数,对油藏研究及后期DST测试设计提供了可靠的依据。以斯伦贝谢的测压取样仪器MDT为例,探讨了MDT测压工具在南海东部海域勘探中的应用。
The application of manometric sampling data in oil and gas exploration has drawn more and more attention and has played a significant role in solving the well logging interpretation and connectivity of complex oil and gas wells. In particular, the identification of reservoir hydrocarbon gas and carbon dioxide has become a very effective means of exploration now. Downhole fluid analysis and sampling is the key to determining fluid properties. The combination of a suitable probe with an optical fluid analysis module not only increases the success rate of the pumping sample, saves operating time, reduces operating costs and the risk of logging operations The fluid properties of the parameters, the reservoir research and post-DST test design provides a reliable basis. Taking Schlumberger MDT as an example, this paper discusses the application of MDT pressure measuring tools in the exploration of the eastern South China Sea.
