摘要
在油气勘探评价阶段,评价试油井产量效果是试油目的之一,也是制定开发方案的重要依据。从影响油井产量的物性参数、压裂措施规模和流体性质三个方面对滴南15区块试油情况进行分析,认为影响该区试油井产量的关键因素为渗透率、有效厚度和压裂规模。该区油层有效厚度为5~10 m,压裂过程中,控制加砂比为15%左右,压裂规模越大,退液率越高,试油效果越好。
In the stage of oil and gas exploration and evaluation,evaluating the production effect of well testing is one of the purposes of well testing and it is also an important basis for making development plans.From three aspects namely physical parameters,fracturing measure scale and fluid property,the oil testing effect of Dinan 15 block is analyzed.The results indicate the key factors influencing the production of the well test in this area are permeability,effective thickness and fracturing scale.The effective thickness of the reservoir in this area is 5~10 m,and in the process of fracturing,the sand adding ratio should be controlled to be about 15%.The larger the fracturing scale is,the higher the fluid withdrawal rate is,and the better the oil testing effect will be.
