辽河边台潜山鱼骨型分支水平井钻井技术

DRILLING TECHNOLOGY OF FISH BONE-BRANCH HORIZONTAL WELLS IN LIAOHE OILFIELD BIANTAI BURIED HILL

鱼骨型分支水平井具有接触更大油藏面积的能力,能由单一井眼控制更大的采油面积。实现MRC技术(最大储层有效控制技术)的主要手段是"鱼骨"型水平井。沈阳采油厂在边台区块裂缝型油藏部署了数口鱼骨型分支水平井,实践证明该技术是一项很有效的钻井新技术。文章研究了在古潜山花岗岩等较硬地层中鱼骨分支水平井钻井技术,为今后施工同类型的井提供了经验和技术支持。

Horizontal well is a good technology to enhance single oil well recovery,and the fish bone-branch horizontal wells have capacity to contact more reservoir area,which can control more production area by a single hole.In recent years,the Liaohe Oilfield carried out MRC(Maximum Range Control) Technology vigorously,that is the largest reservoir control technology.The principal means to achieve MRC technology is fish bone-branch horizontal wells.In Biantai fractured reservoir block,Shenyang Oil Production Plant has deployed several fish bone-branch horizontal wells,the practice has proved that it is a promising and effective new drilling technology,its application and development bring significant economic and social benefits for the Liaohe oilfield development.This article took the Biantai-H9Z,Biantai-H5Z which are two fish bone-branch horizontal wells as example,the fish bone-branch horizontal well drilling technology was studied in the buried hill granite and hard formation,it provided experience and technical support for future construction in same type wells.
