大庆油田发展到至今,随着开采技术的进步,长垣地区薄互层的开发已显的尤为重要,另外老的储油层依然是开采的主力,为了了解地下地层的孔隙度、含油饱和度以及岩石的属性,需要进行取心作业。由于大庆长垣地区油层较厚,主力油层厚达几十米,薄层、夹层较多,所以撞击式井壁取心成为取心方式的首选。取心成功与否涉及井眼情况、地层厚底、岩石硬度、泥浆情况、底层深度等诸多因素,那么如何才能高效、安全的完成取心作业,如何才能不断提高长垣地区撞击式井壁取心的成功率,将是本篇文章所要探究的问题。 Since the development of Daqing Oilfield up to now, with the development of mining technology, the development of thin interbed in Changyuan area has been especially important. In addition, the old reservoirs are still the main mining. In order to understand the porosity, oil saturation, Rock properties require coring work. Due to the thick Daqingyuanyuan oil layer, the main oil layer thickness of tens of meters, thin layers, mezzanine more, so the percussion wall lining coring has become the preferred coring method. Coring success or not involves wellbore conditions, stratum thick bottom, rock hardness, mud conditions, the depth of the bottom and many other factors, then how to efficiently and safely complete coring operations, how can we continuously improve the percussion wall in Changyuan coring The success rate of this article will be to explore the issue.
