在油田开发的井下作业施工中,人们总是认为只要准确丈量组配管柱,就可以准确地把管柱下到目的位置,可实际不一定就能达到目的。这就是人们错误地把管柱丈量深度与油层深度等同看待所致。这样的错误观念,不但影响生产,还易产生错误的认识。本文使我们认识上有一个改变。认识到管柱深度与油层深度之间有一误差值,这个误差值是可以计算出来的。了解并利用了这个误差值,可避免一部分错误,使我们对油层有一个更准确的认识。另外,利用计算出的校正值配下生产管柱,在确保管柱丈量准确的情况下,同样可以达到电测校深的目的,从而可节省一批测井费用。随着油田细分开发生产的深入,薄夹层封堵施工将越来越多,管柱深度与油层深度之间误差值的计算和利用将愈加重要。
In the oilfield development of underground operations, people always think that as long as the accurate measurement group pipe string, you can accurately pipe down to the destination position, but may not actually be able to achieve the goal. This is why people incorrectly equate the measured depth of the pipe with the depth of the reservoir. Such misconceptions not only affect production, but also easily lead to wrong understanding. This article brings us a change in understanding. Recognizing that there is an error between the depth of the column and the depth of the reservoir, this error can be calculated. Understanding and using this error value can avoid some errors and give us a more accurate understanding of the reservoir. In addition, the use of the calculated correction value allocated to the production of the column, to ensure that the measurement of the pipe string accurately, the same can achieve the purpose of electrical measuring school, which can save a number of logging costs. With the deepening of oilfield development and production, the construction of thin interlayer sealing will be more and more. The calculation and utilization of the error between the depth of the pipe and the reservoir will become more and more important.
