摘要
SZK油田位于滨里海盆地,该油田的钻井施工主要存在泥岩段阻卡、砂岩地层井径扩大、井漏、油气层污染等问题。针对该地区地层特点并结合实际钻井施工,制定了合理的钻井液体系及配套的技术措施,有效预防和减少了井漏等复杂情况的发生,提高了井眼质量,缩短了钻井周期,降低了开发成本。
Subject SZK oil field located at the basin of the Precaspian, the main risk of drilling operation in this oil field is drill string easy get stuck during drilling the claystone, wash--out the hole diameter, leakage and contamined in pay zone, etc. Made a suitable measurement in drill fluid system and treatment while drilling in this block, to prevent and reduce the risk of loss circulation and so on, it acctually shorten cycle and lowen the operation cost, and make the hole condition more better.
