摘要： A hydrocarbon-based or ester-based drilling fluid or mud is described wherein the drilling fluid contains cesium phosphate. The hydrocarbon-based or ester-based drilling fluid or mud can have, for example, an external phase that contains hydrocarbon fluid and an internal phase that contains cesium phosphate. The hydrocarbon-based drilling fluid or mud can further contain at least one emulsifier or surfactant, and optionally other ingredients. The present invention can permit hydrocarbon-based drilling fluids to be essentially solids-free and may be used without corrosion and/or formation damage problems, for example, due to the use of the cesium phosphate in an internal phase of the hydrocarbon-based or ester-based drilling fluid. The present invention also relates to hydrocarbon-based or ester-based fluids for completion, workover, suspension and packer operations which contain cesium phosphate.
摘要翻译：描述了一种烃基或酯基钻井液或泥浆，其中钻井液含有磷酸铯。烃基或酯基钻井液或泥浆可以具有例如含有烃流体和含有磷酸铯的内相的外部相。烃基钻井液或泥浆可以进一步含有至少一种乳化剂或表面活性剂，以及任选的其它成分。本发明可以允许基于烃的钻井液基本上是无固体的，并且可以不使用腐蚀和/或地层损伤问题来使用，例如，由于在烃基的内相中使用磷酸铯或酯基钻井液。本发明还涉及含有磷酸铯的用于完成，修井，悬浮和封隔器操作的烃基或酯基流体。
