摘要
在采用冷41-平1水平井技术开发冷41块厚层-块状底水超稠油油藏过程中,针对油层底水能量大,锥进严重,且深度不确定等问题,提出在水平井施工过程中用大斜度导眼钻穿入靶点前方油层及底水,从而确定油水界面深度,确保水平段在油层中钻进,对冷41-平1水平井从地质情况、导眼设计、实施情况等方面对大斜度导眼进行了简要介绍,通过大斜度导眼的实施,缩短了钻井进尺,保证了水平井的实施效果。
In development of long 41 thick bottom wa ter supper ?heavy oil reservoirs by adopting Ieng41 pingl horizontal well technology, there are some problems existent in drilling, such as bottom water zone of great energy ,serious coning, unconfirmed water oil depth and so on In order to confirm water - oil surface depth, insure horizontal section drilling in oil zone, high inclination pilot well is proposed to drill cross the oil zone and bottom - water zone before the first target. This article introduces geologic framework ? design? construction and so on of high inclination pilot well Through construction of high inclination pilot well, the drill footage of horizontal well is decreased, and the good drilling effect is obtained.
