摘　　要：针对苏北溱潼凹陷疏松砂岩稠油油藏具有埋深浅、岩性松、油层薄、夹层多、易出砂、油质稠的特点,开展了溱潼凹陷疏松砂岩稠油油藏水平井开采工艺技术研究。介绍了溱潼凹陷疏松砂岩稠油油藏水平井防砂完井工艺技术、泡沫酸化解堵工艺技术、螺杆泵举升工艺技术和乳化降黏工艺技术。自2009年以来,共开展稠油水平井开采工艺技术现场试验12井次,工艺成功率100%,有效率100%。Against the loose sandstone heavy oil reservoir of Qintong sag in north Jiangsu,which is characterized with low burial depth,slack lithology,thin layers,multiple interbeds,easy sand flow and heavy oil,researches were conducted on the technologies of horizontal wells development of loose sandstone heavy oil reservoir.This paper introduced series of technologies for the horizon tal wells development,including sand control and well completion technologies,foam acid plugging removal technology,screw pump lifting technology and emulsification viscosity reduction process technology.Since 2009,a total of 12 well times of field tests concerning heavy oil reservoir horizontal wells development were carried out,achieving the success rate of 100 % and the effective rate of 100%.
