摘要:
楊武寨構造帶是饒陽凹陷油氣富集區之一,具有較大的資源潛力,油層呈“牙刷狀”分布特征,為提高鉆遇油層厚度和油藏儲量控制程度,鉆井方式由早期直井鉆探為主轉為以大斜度定向井為主。針對定向井鉆井過程中,存在托壓嚴重、工具面難以控制、機械鉆速慢、鉆遇第三系地層多次發生卡鉆及低滲儲層易受傷害等問題,開展了優快鉆井技術研究,優選了軌道剖面、優選提速工具、優化鉆井液性能。通過現場應用,鉆井過程中實現無托壓、無黏卡、定向連續,與鄰井同井深相比,平均機械鉆速提高50.5%,鉆井周期縮短9 d,可以在類似油藏推廣應用。
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.
