摘要
介绍准噶尔盆地YJ井区砂岩油藏侏罗系储层发育特征和试采进展。2004年,Y1井5 873~5 888 m井段试油,日产油72 m3/d,日产气10 562 m^(3)/d,发现YJ井区。生产层油层厚度8.4 m,层理缝比较发育,异常高压。Y3-CP1井完钻井深6 111 m,水平段374 m,采用自喷投产,油压46 MPa,日产油62 t/d、日产气18 000 m^(3)/d,不含水,已累产油3.554 9×10^(4)t,累产天然气1.1×10^(7)^(3)。Y3-CP1井原油可采储量为6×10^(4)t。YJ井区已有9口井获得工业油流,到2022年8月,累产油8.8×10^(4)t。
The development characteristics and trial production progress of Jurassic sandstone reservoir in YJ well area of Junggar basin are introduced. In 2004, YJ well block was found in the 5 873~5 888 m section of Well Y1, with a daily oil output of 72 m^(3)/d and a daily gas output of 10 562 m^(3)/d. The thickness of the oil layer in the production layer is 8.4 m, the bedding fractures are relatively developed, and the pressure is abnormal. Y3-CP1 has a completed drilling depth of 6 111 m and a horizontal section of 374 m. It is put into production by self injection. The oil pressure is 46 MPa, the daily oil output is 62 t/d,and the daily gas output is 18 000 m^(3)/d. It does not contain water, and the accumulated oil production is 3.554 9×10^(4)t, cumulative natural gas production 1.1×10^(7)m^(3). The recoverable reserves of crude oil in well Y3-CP1 are 6×10^(4)t. Nine wells in YJ well area have obtained industrial oil flow. By August 2022, cumulative oil production 8.8×10^(4)t.
