在油井抽汲试油过程中,为了能正确评价、认识目的层,抽汲的液体是否能全部回收并准确计量成为关键。由于滚轮式防喷盒密封性能差,一方面无法准确计量地层的产液能力,不利于对油层的认识和评价;另一方面泄漏的含油污液浸流井场,如遇大雨,污液灌入农田污染环境。为了解决上述问题
In oil well pumping test oil process, in order to correctly evaluate, to know the target layer, pumping the liquid can be fully recovered and accurately measure the key. Because of the poor performance of the wheel-type spray-proof box sealing, on the one hand can not accurately measure the production capacity of the formation, is not conducive to understanding and evaluation of the reservoir; on the other hand leaking oily liquid soaking flow well, in case of heavy rain, Enter the farmland to pollute the environment. In order to solve the above problems
