摘要
水平井技术是一项技术含量高、多学科联合紧密的新技术。对于川渝油气田复杂的储层地质条件 ,尽管水平井技术应用较早 ,但增产效果一般 ,针对这些特点 ,在广泛调研的基础上 ,结合川渝油气田的实际 ,提出了水平井储层的选定、技术经济分析、钻进过程中入靶点的确定、水平段轨迹设计、完井方式、产层保护等方面的运作思路和方法 ,进行了一定程度的探索 ,得出了有益的认识 ,对川渝油气田水平井的勘探开发有一定的参考价值。
Horizontal well technology is an advanced new technology with team work. For the complex oil zone in the Sichuan oilfield, although the horizontal well technology was utilized early, the results from promotion of oil and gas were not satisfied. For the sake of this, on the basis of investigation of use of horizontal well technology at home and abroad, along with the actual situation of the oilfield, this paper have studied the selection of pay zone, analysis of both technology and economy, determination of hitting targets, planning of well path, completion, and damage of oil zones, and some useful results have been achieved. It will have some important effects on the development of Sichuan oilfield using horizontal well technology.
