目前在塔河油田无论是碳酸盐岩油藏还是砂岩油藏都存在底水锥进造成油井含水上升快、产油量递减快的现象,含水快速上升是塔河油田产量递减的主要原因。在认真分析塔河油田水锥形成原因基础上,借签国内外防锥、消锥方法,结合塔河油田生产实际情况,开展了大量的富有特色的防锥、消锥工作,提高了产量。

At present some producing oil wells ar e experiencing rapid increase of water-cut and serious production decline which  are caused by bottom water conning in both carbonate and sandstone reservoir of  the Tahe oilfield, water-cut quickly raising is one of the main reasons for th e serious production decline in the Tahe oilfield. Through detailed analysis wat er conning mechanism and study those technologies of avoiding and eliminating wa ter conning at domestic and overseas, a great deal of work has been carried out  on the basis of practical performances of the Tahe oilfield. We have acquired so me achievement and established characteristic techniques about avoiding and elim inating water conning in the Tahe oilfield.
