低渗透薄油层四分支鱼骨水平井设计与施工

目前鱼骨水平井技术已经成为国内外低产油田增产,老油田二次、三次采油,提高开发经济效益的重要手段。为了探索四分支鱼骨水平井开发大庆外围低渗透薄油层的可行性,大庆油田有限责任公司井下作业分公司以肇州油田试验区块为研究对象,开展了井网及井轨迹参数优化研究,并在精细的水平井钻井地质导向技术方案指导下,设计、实施了州72-平54Z井鱼骨水平井钻进,取得了良好的钻探效果。实践结果表明,大庆外围低渗透薄油层实施鱼骨水平井技术开发是可行的。

Drilling and Construction of Four-branch Herringbone Horizontal Well in Low Permeability Thin Reservoir

Now the herringbone horizontal well technology has become an important approach to the production improvement in low-yield oilfields both at home and abroad and the secondary and tertiary oil recovery in old oilfields as well as the enhancement of economic performance of oilfield. To probe into the feasibility of developing low permeability thin reservoir in Daqing peripheral oilfields with the four-branch herringbone horizontal well technology, the Downhole Operation Division of Daqing Oilfield Company Limited took the trial area of Zhaozhou Oilfield as the study object, carried out well pattern and well trajectory parameter optimization study, designed and implemented drilling of Zhou 72-Ping 54Z herringbone horizontal well under the guidance of fine geosteering technical scheme for horizontal well drilling, and obtained good drilling results. Practical results show that to developthe herringbone horizontal well technology is feasible in low permeability thin reservoir in Daqing peripheral oilfields.
