摘要:
秦皇岛32-6油田是典型的海上低幅稠油底水油田,由于其构造幅度低,油层厚度小于10 m的储量比例占22%. 为了高效动用此类储量,在岩心分析和夹层测井识别的基础上,采用数值模拟方法充分利用夹层较发育的特点,开展了夹层对水平井开发的影响以及水平井布井界限研究。研究结果表明,夹层渗透率与基岩渗透率比值为0.01时,夹层能有效阻挡底水的快速锥进;夹层面积为水平井泄油面积的2~3倍时,能使底水发生绕流且使储量动用程度最大化;夹层位于距油层顶面3/4油层厚度处时,可有效延缓底水锥进速度,同时扩大水驱波及体积;以累计产油量5×104 m3作为可布水平井的经济极限下限,海上低幅稠油底水油藏可布水平井油层厚度下限值为5 m. 矿场先导试验证实了该结论的可靠性,为低幅稠油底水油藏水平井布井提供了技术支持。
Abstract:
Qinhuangdao 32-6 oilfield is a typical offshore low-amplitude bottom-water heavy oil field. Oil reservoirs with the thickness of less than 10 m account for 22% due to the low amplitude of the oilfield. To produce this kind of reserves efficiently, and based on interlayer logging identification and core analysis, the paper carries out a study on the influences of interlayer on development and well allocation limits of horizontal wells by using numerical simulation method. The study results show that interlayer can effectively block the rapid coning of bottom water when the permeability ratio of interlayer to basement is 0.01; interlayer will allow bottom water to flow around and the producing degree of reserves will reach the maximum when the interlayer area is 2~3 times of oil drainage area in horizontal wells; interlayer will effectively slow down the coning speed of bottom water and meanwhile will enlarge swept volume of water flooding when the interlayer is located in the position with the distance to reservoir top of 3/4 reservoir thickness. Taking cumulative oil production of 5×104 m3 as the lower economic limit for horizontal well allocation, the lower limit of reservoir thickness for horizontal well allocation should be 5 m in offshore low-amplitude heavy oil reservoirs with bottom water. Pilot tests in fields have proved the reliability of the technology, providing technical support for horizontal well allocation in low-amplitude heavy oil reservoirs with bottom water.
