摘　　要：文章简要介绍了微差井温测井和硼中子测井在油井中找水的基本原理和施工工艺,用具体井例分析说明了两种测井方法的优缺点,通过对比分析,发现两种测井方法适应不同的地质条件。微差井温测井对于射孔间距比较大,产液量大的井效果比较好,对于低产夹层薄的井就无能为力;硼中子测井能够直观定量各射孔层位的剩余油分布情况,分辨率比较高,能够分辨0.3 m的薄层,但是对于层间矛盾比较大的射孔层段,有可能误解释。因此,建议有关人员在油井找水时,一定要根据油井的具体地质情况确定合适的测井方法,这样才能有效地找出出水层位,把含水降下来,真正达到增油的目的。This paper briefly introduces the fundamental principle and construction technology of differential temperature well logging and boron neutron well logging in water finding in oil wells,describes advantages and disadvantages of differential temperature well logging and boron neutron well logging with specific well cases analysis.Comparison analysis finds two well logging methods adapt different geological conditions.Differential temperature well logging has good effects in larger shot hole spacing and larger volume liquid producing well,and fails to low-yield sandwich thin well.Boron neutron well logging can intuitively quantize remaining oil distribution situation of all shot hole layer, with high resolution.It can discriminate 0.3 m of thin layer,but has false interpretation for the shot hole layer segment existing interlayer contradiction.Therefore,it must determine appropriate logging method according to specific geological conditions,so that it can effectively identify the water layer,truly achieve the goal of increasing oil production.
