不关井及短时关井测压法,76～77年曾在马岭油田进行过十三口井二十一井次矿场试验,计算压力与试错法确定的压力对比,平均误差1.18大气压,与关井实测压力对比,平均误差1.28大气压。78年进一步在李庄子、马家滩及大水坑三个油田的9口井,进行了13井次不关井及短关井测压实验,其结果,计算压力与试错法对比7井次,平均误差2.08大气压,与实测压力对比10井次,平均误差2.92大气压。初步成果表明,延安统油井可以应用这个方法测压。现分四方面总结如下:(一)试井原理及公式推导关于不关井或短时关井试井方法,目前国外已有多种,下面主要介绍文献[1]所研
No well shut-in and short-time shut-in manometry, 76 to 77 years in the Maling oil field had 21 wells 21 wells test, calculated pressure and trial and error method to determine the pressure contrast, the average error of 1.18 Atmospheric pressure, compared with the measured well pressure, the average error of 1.28 atm. In 1978, 9 wells in Li Zhuangzi, Majiatan and Dashuikeng fields were further subjected to 13 well shut-in and short-shutoff manometry tests. As a result, the calculated pressure was compared with trial and error Times, the average error of 2.08 atm, compared with the measured pressure of 10 wells, the average error of 2.92 atm. The preliminary results show that this method can be applied to measure pressure in Yan’an oil well. Now divided into four areas are summarized as follows: (a) test well principle and formula derivation About well or short time shut-in well test methods, there are a variety of foreign countries, the following mainly introduces the literature [1]
