松辽地区油气勘探优快钻井技术思路

吉林松辽地区的腰英台、秦家屯十屋、八屋区块以及梨树断陷、长岭断陷的外围中深探井和伏龙泉浅层气井是中石化东北地区的重点区块。自勘探开发以来钻井提速面临重重困难,2010年是中原油田钻井队伍进入该市场以来的提速年,以提速为目标,大胆创新,通过大量的邻井调研分析,针对不同井的特点分别制定了不同的钻井提速措施。在成熟的钻井模式下通过不断地、连续地优化钻头选型,强化钻井参数,推广大功率高温螺杆复合钻进技术,细致的单井钻井方案优选,挖掘提速潜力,创出了有史以来最好的钻探成绩。详细介绍了松辽地区油气勘探优快钻井技术方案及具体措施。

Optimized and Fast Drilling Technology for Oil and Gas Exploration in Songliao Area

The medium exploration wells of Yaoyingtai, Qinjiatunbawu, Qinjiatunshiwu block and surrounding Lishu fault depression and Changling fault depression of Songliao area in Jilin are important in China Petroleum & Chemical Corporation of northeast area, as well as shallow gas well of Fulongquan. Different efficiency improvement measures were respectively made according to the characteristics of each well. Through constant bit optimization, enhancing drilling parameters, adopting high power and high temperature composite screw drilling technology, designing detailed single well drilling schemes and developing efficiency potential, the best drilling record was obtained. The paper introduced the optimized and fast drilling technical schemes and the specific measures in Songliao area.
