为了在无法进行环空测试的抽油机井中测量产液剖面,研究了抽汲式产液剖面测井技术。该技术可在油井检泵作业施工期间进行,在井下2000m以内套管上悬挂空心测试抽汲泵,通过油管驱动深抽产液,测试仪器从油管下入并过泵柱塞到达测试层段,进行不停抽测试,得到产液剖面资料,判断出主产水层,进行有针对性的卡堵水作业。该技术适用于斜井、稠油井、螺杆泵井、电潜泵井、水力泵井等无法进行环空测试的油井。在中原油田成功实施了40余井次,为油田开发方案的判定提供了准确的资料。
In order to measure the liquid production profile in a well that can not be used for annulus testing, the pumping production profile logging technology is studied. The technology can be carried out during the construction of the oil well inspection pump. The hollow test suction pump is hung on the casing within 2000m downhole, the deep pumping liquid is driven through the oil pipe, the test instrument goes down from the oil pipe and reaches the test section through the pump plunger, Continuously pumping tests were conducted to obtain liquid production profile data to determine the main production aquifers, targeted card plugging operations. The technology is suitable for inclined wells, heavy oil wells, screw pump wells, ESP wells, hydraulic pump wells can not be annulus test wells. More than 40 wells were successfully implemented in Zhongyuan Oilfield, which provided accurate information for the judgment of oilfield development plan.
