据海外媒体11月1日卡尔加里报道,加拿大超准能源控股有限公司(超准能源)周三宣布,该公司日前已完成位于中国东海33/07区块的第一口勘探井LS23-1-1井的钻井作业,该公司现在将继续实施LS30-3-1井的勘探钻井计划。
LS23-1-1井在9月23日开钻并在10月21日钻到了8747英尺(2666米)总深度,该井随后获取了电缆测井数据。LS23-1-1井在钻进过程中钻遇了古新世和早白垩世的砂岩地层。
LS23-1-1井发现了几个含气砂岩地层,测井资料的评价结果显示,此井共钻遇了46英尺(14米)厚的纯产层。
由于LS23-1远景构造是一个油气技术发现,但不可能是一个商业发现,因此,超准能源封堵并放弃了这口井并将根据商定好的两口井钻探计划进行第二口井LS30-3-1井的钻井作业。

Primeline Completes Drilling at LS23-1-1 in Block 33/07 in East China Sea

Primeline Energy Holdings Inc. announced Wednesday that it has completed the drilling operations of the LS23-1-1 well in Block 33/07 in the East China Sea and will now continue with the exploration drilling program for the LS30-3-1 well.
The LS23-1-1 well was spud Sept. 23 and reached total depth (TD) of 8,747 feet or (2,666 meters) Oct. 21 and wireline logging data was subsequently acquired. The well encountered sandstone units of Paleocene and early Cretaceous age. It discovered several zones of gas bearing sandstone and evaluation of logging data indicated total cumulative net pay thickness of 46 feet (14 meters). The LS23-1 prospect is a technical discovery of hydrocarbon but not likely to be a commercial discovery. Therefore Primeline has plugged and abandoned the well and will proceed with the drilling of the LS30-3-1 well on the basis of the agreed two well work program.
