海上油田自适应控水完井技术研究及现场试验

The application of Autonomous water control technology in the development of Offshore Oilfield

为解决水平井开发过程中底水快速锥进问题,自适应控水完井技术在流入控制装置(ICD)控水技术的优势上,中后期通过“自动控制流量”作用,抑制水平段高含水段出液,起到延缓油井含水上升作用。X油田H油藏W1井采用自适应控水完井技术油井,截至目前累产油9.5万m^(3),较W1井预测增加1.2万m^(3)。分析认为自适应控水技术,对水平井开发过程中含水上升可以起到一定的抑制作用。

In order to solve the problem of bottom water rapid coning in horizontal well development.In terms of the advantage of the ICD water control completion technology.At later stages,the autonomous water control completion technology can automatically control liquid to constrain the high water section,which can slow down the water cut increase.Well W1 in H reservoir of X oilfield adopts autonomous water control completion technology.Up to now,cumulative oil production is 95,000m^(3),which 12,000 higher than the forecast results.The analysis shows that the water control completion technology can restrain the rise of water cut in the process of horizontal well development.
