发布时间：2018-09-19 12:29
【摘要】：中国渤海海域已经进入勘探与开发的发展重要阶段,为了增加产量,降低钻井投入,很多区块的开发工作需要钻水平井、多底井。在钻探的过程中,为了不钻或少钻领眼,准确、快速的完成钻井任务,现场的井眼轨迹实时地质跟踪技术将起到关键的作用。有效的、成熟的地质实时跟踪技术可以确保钻井任务的顺利完成,确保井眼轨迹符合设计要求。B油田是渤海海域内第四大油田,该油田发现的油层主要在明化镇下段,为正常的温度、压力系统,海拔在1650~1850米深。岩性特征为一套泥岩与砂岩的不等厚互层,砂岩单层厚度2~20m不等。为了有效的增大产出,降低成本,设计在该油田开发过程中将钻探多口水平井(及多底井),按照设计每口井均需要钻领眼。目前国际石油行业中,水平井(及多底井)已经是一种相当成熟的技术。本文分析和研究出一套针对B油田地质情况的井眼轨迹实时地质跟踪技术,可以保证该油田水平井(及多底井)的成功钻探,以达到少钻或不钻领眼的目的,在以后的勘探与开发过程中做到少投入、多产出。
[Abstract]:The Bohai Sea area in China has entered an important stage of exploration and development. In order to increase production and reduce drilling investment, horizontal wells and multi-bottom wells are required for the development of many blocks. In the process of drilling, in order to complete the drilling task accurately and quickly, the real-time geological tracking technology will play a key role. Effective and mature geological real-time tracking technology can ensure the smooth completion of drilling tasks and ensure that wellbore trajectory meets the design requirements. Oil field .B is the fourth largest oil field in the Bohai Sea area. The reservoir found in the oilfield is mainly in the lower section of Minghua Town. For normal temperature, pressure system, elevation at 1650m 1850 m. The lithology is characterized by a set of interbedded layers between mudstone and sandstone, and the thickness of single layer of sandstone varies from 2m to 20m. In order to increase the output effectively and reduce the cost, it is designed to drill multiple horizontal wells (and multi-bottom wells) in the development process of the oilfield, and each well needs to be drilled according to the design. At present, horizontal well (and multi-bottom well) is a very mature technology in international petroleum industry. In this paper, a set of real-time geological tracking techniques for borehole trajectory in B oilfield are analyzed and studied, which can ensure the successful drilling of horizontal wells (and multi-bottom wells) in this oil field, so as to achieve the goal of less drilling or no drilling. In the later exploration and development process to do less input, more output.
