多底井钻井技术

The Drilling Technology for Multi-Bore Well

多底井是开发低渗透油田或枯竭老油田的一种十分有效的方法，尤其是水平分支底井，更是开发小断块、薄油层、多层油藏、裂缝油藏以及减少水气锥进等的一种重要手段。多底井技术对提高油气井产量、降低油气井综合成本具有很大的实用价值。本文主要针对各种类型多底井的钻井技术特点进行了扼要描述。多底井技术在我国具有广阔的应用发展前景。

Multi-Bore well technology is a very efficient method for developing low-permeability ordepleted oilfields, especially, the horizontal-branched multi-bore wells may be used for the development of small fault-block reservoir, thinner reservoir and multi-zone reservoiras well as fracture reservoir. At the same time,it is also an important method of reducing water-gas coning. This technology will be of great practlcal value to increasing oil-gas output and reducing costs. Thedrilling technical characteristics of multi-bore wells are described simply in this paper and showed brightfuture in petroleum industry.
