摘要:
杨武寨构造带是饶阳凹陷油气富集区之一,具有较大的资源潜力,油层呈“牙刷状”分布特征,为提高钻遇油层厚度和油藏储量控制程度,钻井方式由早期直井钻探为主转为以大斜度定向井为主。针对定向井钻井过程中,存在托压严重、工具面难以控制、机械钻速慢、钻遇第三系地层多次发生卡钻及低渗储层易受伤害等问题,开展了优快钻井技术研究,优选了轨道剖面、优选提速工具、优化钻井液性能。通过现场应用,钻井过程中实现无托压、无黏卡、定向连续,与邻井同井深相比,平均机械钻速提高50.5%,钻井周期缩短9 d,可以在类似油藏推广应用。
Abstract:
Yangwuzhai structural zone is one of the hydrocarbon enrichment zones in Raoyang sag, and its resource potential is huge. Its oil layers are distributed in the shape of toothbrush, so in order to increase the drilling thickness of oil layers and the reserve control degree of oil reservoirs, the drilling mode is transformed into the high-angle directional well from the vertical well in the early stage. In this paper, optimal and fast drilling technologies were studied, including track section selection, ROP (rate of penetration) improvement tool selection and drilling fluid property optimization, to deal with the problems in the drilling process of directional well, e.g. serious backing pressure, hard control of tool face, low ROP, frequent pipe sticking in Tertiary and vulnerable low-permeability reservoir. When the optimal and fast drilling technologies are applied to the field, directional and continuous drilling without backing pressure and sticking is realized. And compared with the same depth in its neighboring well, its average ROP is 50.5% higher and drilling period is 9 d shorter. The research results can be popularized and applied in the similar oil reservoirs.
